Description

The present invention relates to a job processing system that performs job processing, a job processing method, a printing apparatus, a storage medium, and a program.

  In the conventional printing industry, publications are issued through various work processes. Specifically, manuscript submission, design assignment to the manuscript, layout editing, comp (print presentation), proofreading (layout correction and color correction), proof printing (proof printing), composition creation, printing, There are post-processing and shipping.

  In the conventional printing industry, an offset plate-making printing machine is used in the printing process, so that a block making process is required. However, once this composition is created, it is not easy to modify it. Therefore, careful proofreading (that is, careful layout check, color confirmation work, etc.) is indispensable for creating a composition. For this reason, it took a lot of time to issue a publication.

  In addition, many of the devices used in each work process are large-scale, and special knowledge is necessary for handling them, so the know-how of skilled workers is indispensable.

  In recent years, a POD (Print On Demand) system using an electrophotographic printing apparatus or an inkjet printing apparatus has been proposed (see Patent Document 1). Such a POD system eliminates the need for creating a composition as described above and other complicated operations. In recent years, JDF compatibility has been progressing as a printing apparatus for the POD market. This JDF is a common digital format (also referred to as an instruction sheet or a job ticket) that is expected in the future for a system for the POD market defined by CIP4 and related to the entire printing process. This JDF is an abbreviation for Job Definition Format. CIP4 is an abbreviation for “Cooperation for the Ingegration of Processes in Prepress, Press and Postpress”. JDF uses XML, which is the basic format of the Web, for its format. Utilizing this characteristic, there are expected management advantages relating to the overall printing process, such as production management on the website and confirmation of the operating status of each device such as a printing machine and bookbinding machine.

  In addition, by using the JDF format instructions, instructions related to a series of work processes from the submission process to the delivery process related to the printed matter that is the final product are not limited to a single device but are linked by a plurality of devices. Can be described. By utilizing this feature, a series of workflows composed of a plurality of processes using a plurality of devices can be managed with a single instruction. As a result, it is expected to provide merits in cooperation between a plurality of devices related to the entire printing process and automation of various devices.

  Under the background as described above, studies aiming at practical application of a JDF-compatible printing apparatus that can make maximum use of the merits of this JDF as a printing system for the POD market are being made.

US Publication No. 2004-0190057

  However, for example, when the digital multi-function peripheral supports JDF, it is necessary to enable a print setting instruction using a job ticket. Unlike a printer driver, this job ticket can be created even if device specifications and configuration information are unknown. This is a JDF-specific advantage aimed at enabling jobs to be processed by various devices as much as possible in a common format that does not depend on one device.

  However, when this situation is assumed and an attempt is made to actually configure a printing apparatus or system, there are problems and user needs that should be dealt with anew that have not been achieved so far. For example, depending on the execution environment (device capabilities, attached accessories, etc.), there may occur a case where the operation instructed by the job ticket cannot be executed entirely by the printing apparatus (printing system). Further, considering from the viewpoint of the user, for example, when printing is instructed using a job ticket, there may be a case where the printing apparatus (printing system) cannot perform printing as instructed. In this case, it is desirable that the user can cancel the processing of the job. For example, in a printing environment in the POD market, a printed material is likely to be handled as a product delivered to a customer. In a printing system of such a printing environment, a printed matter that cannot be delivered to a customer is handled as a useless output, which results in a failure cost and should be eliminated as much as possible from the cost aspect. Therefore, it is necessary for the user (operator) in the POD environment to cope with such a request in order to eliminate the erroneous output product and reduce the cost.

  On the other hand, there are cases where the user desires to print with the printing apparatus (printing system) even if not all the settings are reflected. For example, in the above-described printing environment (printing site), the finisher included in the printing apparatus cannot process the job. However, when other finishers are used, the job may be processed. In this case, first, a printed material is obtained by the printing apparatus, and then the printed material is set on the finisher to obtain a desired printed material.

  Thus, JDF format data can be expected in terms of versatility, device automation, device cooperation, device management, and the like. However, since it is not data prepared only for one device or a specific type of device, it is difficult to deal with it by simply providing a JDF-compatible printing device or printing system in the printing environment described above. Can occur.

  However, since it is now in the stage of studying the practical use of such products and systems, it has not been studied until various cases and user needs can be dealt with.

The present invention provides a job processing system, a job processing method, a printing apparatus, a storage medium, and a program that enable flexible processing when executing a job.

  For example, when executing a job instructing post-processing for a printed sheet, an object is to enable flexible processing even when the post-processing cannot be executed.

The present invention relates to a job processing system that causes a post-processing unit to perform post-processing on a printed sheet, and a confirmation unit that confirms that post-processing instructed by the job cannot be executed by the post-processing unit, and a job After the confirmation by the confirmation means that the post-processing instructed in the step cannot be executed by the post-processing means, a setting means for allowing the user to set whether or not to change the job execution order, and instructed by the job Control means for changing the job execution order when it is confirmed by the checking means that the post-processing cannot be executed by the post-processing means, and when the setting means is set to change the job execution order; It is characterized by having.

Further, the present invention is a job processing method for causing a post-processing unit to perform post-processing on a printed sheet, and after confirming that the post-processing instructed by the job cannot be executed by the post-processing unit, A setting step for causing the setting means to receive an instruction from the user indicating whether or not to change the job execution order, and a case where it is confirmed that the post-processing means specified by the job cannot be executed by the post-processing means, and And a step of causing the control means to change the job execution order when the job execution order is changed via the setting means.

The present invention can provide a job processing system, a job processing method, a printing apparatus, a storage medium, and a program that can execute flexible processing when executing a job.

[Apparatus configuration of printing system 1000 (mainly mechanical configuration)]
FIG. 3 is a diagram illustrating the hardware configuration of the printing system 1000.

  The sheet processing apparatus 200 in the printing system 1000 according to the present embodiment can connect any number of apparatuses of any type as long as the sheet can be conveyed from the upstream apparatus to the downstream apparatus via the sheet conveyance path. For example, as shown in FIG. 3, the large-capacity stacker 200-3a, the gluing bookbinding machine 200-3b, and the saddle stitch bookbinding machine 200-3c can be connected in the order closest to the printing apparatus 100. Each of the sheet processing apparatuses 200 includes a sheet discharge unit, and a user can take out a sheet subjected to sheet processing from the sheet discharge unit of each sheet processing apparatus 200. The above-described control unit 205 performs the following processing on the sheet processing apparatus 200 connected to the printing apparatus 100 based on an instruction received from the user.

  For example, it is assumed that for a certain print job, the user uses the operation unit 204 to instruct to perform a large number of sheets. In this case, the control unit 205 causes the printing apparatus 100 to execute the printing process for the sheets of the print job, and then performs a large-volume stacking process for the printed sheets on the large-capacity stacker 200-3a connected to the printing apparatus 100. Let it run.

  On the other hand, it is assumed that for a certain print job, the user gives an instruction to perform a case binding process using the operation unit 204. In this case, the control unit 205 causes the printing apparatus 100 to execute the printing process for the sheet of the print job, and then performs the case binding process for the printed sheet on the glue binding machine 200-3b connected to the printing apparatus 100. Let it run.

  Further, it is assumed that for a certain print job, the user uses the operation unit 204 to instruct the book binding process. In this case, the control unit 205 causes the printing apparatus 100 to execute the printing process for the sheet of the print job, and then performs the glue binding process for the printed sheet on the glue binding apparatus 200-3b connected to the printing apparatus 100. To run.

  On the other hand, it is assumed that for a certain print job, the user uses the operation unit 204 to instruct the saddle stitch binding process. In this case, the control unit 205 causes the printing apparatus 100 to execute the printing process for the sheet of the job, and then causes the saddle stitch binding machine 200-3c connected to the printing apparatus 100 to execute the stapling of the printed sheet. . Similarly, when the user instructs via the operation unit 204 to perform any one of punching, cutting, folding, and saddle stitching, the control unit 205 performs the instructed sheet processing. The saddle stitch binding machine 200-3c connected to the printing apparatus 100 is executed.

  As described above, the control unit 205 sends a request for executing the sheet processing of the type desired by the user to the operation unit 204 from among the types of sheet processing candidates that can be executed by the sheet processing apparatus 200 connected to the printing apparatus 100. Via the print execution request. In response to receiving a print execution request for the job from the user, the control unit 205 causes the printer unit 203 to execute print processing required for the job. Then, the control unit 205 conveys the sheet of the job subjected to the printing process to the sheet processing apparatus 200 capable of executing the sheet processing desired by the user via the sheet conveyance path, and the sheet processing apparatus 200 instructs the sheet. Execute sheet processing.

  For example, if the job to be processed that has received a print execution request from the user is a job instructed to perform a large-volume stacking process by the large-capacity stacker 200-3a, this job is referred to as a “stacker job”. When this stacker job is processed by the system shown in FIG. 3, the control unit 205 conveys the sheet of the job printed by the printing apparatus 100 to the large-capacity stacker 200-3a through point A in FIG. Let Thereafter, the control unit 205 causes the large-capacity stacker 200-3a to execute the job stacking process. Then, the control unit 205 does not convey the printed matter of this job that has been stacked by the large-capacity stacker 200-3a to another apparatus (for example, a subsequent apparatus), and discharges the paper in the discharge destination X inside the large-capacity stacker 200-3a To hold. Next, the user can directly take out the printed material of the stacker job held at the paper discharge destination X from the location of the paper discharge destination X. 3 eliminates the need for a series of apparatus operations and user operations such as conveying the sheet to the most downstream sheet discharge destination Z in FIG. 3 and taking out the printed material of the stacker job from the sheet discharge destination Z. .

  In addition, a job to be processed that has received a print execution request from the user is a job that performs sheet processing (for example, glue binding processing of either case binding processing or top binding binding processing) by the glue binding machine 200-3b. Suppose there is. This job is called a “glue binding job”. When this glue binding job is processed by the system shown in FIG. 3, the control unit 205 conveys the sheet printed by the printing apparatus 100 to the glue binding machine 200-3b via points A and B in FIG. Let Thereafter, the control unit 205 causes the glue binding apparatus 200-3b to execute the glue binding process for the job. Then, the control unit 205 does not convey the printed material that has been subjected to the gluing bookbinding process by the gluing bookbinding machine 200-3b to another apparatus (for example, a subsequent apparatus), and directly outputs the paper output destination Y of the gluing bookbinding machine 200-3b. Hold on.

  Furthermore, for example, in the system of FIG. 3, it is assumed that the job to be processed that has received a print execution request from the user is a job instructed to perform sheet processing by the saddle stitch binding machine 200-3c. Examples of sheet processing performed by the saddle stitch binding machine 200-3c include saddle stitch binding, punch processing, cutting processing, shift paper discharge processing, and folding processing. Here, this job is referred to as a “saddle stitching job”. When processing this saddle stitch bookbinding job, the control unit 205 causes the sheet of this job printed by the printing apparatus 100 to be conveyed to the saddle stitch bookbinding machine 200-3c via points A, B, and C. Thereafter, the control unit 205 causes the saddle stitch bookbinding machine 200-3c to execute the saddle stitch bookbinding process. Then, the control unit 205 holds the printed matter of the saddle stitch bookbinding job that has been subjected to the sheet processing by the saddle stitch bookbinding machine 200-3c in the paper discharge destination Z of the saddle stitch bookbinding apparatus 200-3c. There are a plurality of delivery destination candidates in the delivery destination Z. This is used when the saddle stitch bookbinding machine 200-3c can execute a plurality of types of sheet processing and separates the paper discharge destination for each sheet processing.

  The printer unit 203 of the printing apparatus 100 according to the present embodiment forms a toner image corresponding to an image signal on the photoconductor 304 and transfers the toner image to the transfer roller 305 to form a color composed of Y, M, C, and K. An image is formed and transferred to a sheet for printing. Since the printer unit 203 is known, a detailed description thereof will be omitted.

  The printing system 1000 according to the present embodiment described above can connect a plurality of sheet processing apparatuses 200 to the printing apparatus 100. The plurality of sheet processing apparatuses 200 can be connected to the printing apparatus 100 in any combination. Also, the connection order of the plurality of sheet processing apparatuses 200 can be freely changed within a range where the sheet conveyance paths between the apparatuses are connected. There are also a plurality of types of sheet processing apparatuses 200 that can be connected to the printing apparatus 100.

  Next, the internal configuration of the sheet processing apparatus 200 that can be connected to the printing apparatus 100 will be described by type with reference to FIGS. 4 to 6.

  FIG. 4 is a cross-sectional view illustrating the large-capacity stacker 200-3a.

  The large-capacity stacker 200-3a selectively conveys the sheet conveyed from the upstream printing apparatus 100 to three conveyance paths. One is a sample tray path 4000 for discharging to the sample tray. One is a stack path 4001 to be sent to the stack tray, and the other is a straight path 4002 for simply passing through. The stack tray 4003 is a stacking unit that is placed on an extendable stay 4004 or the like. Under this extendable stay 4004, a detachable carriage 4005 is provided. Using this cart 4005, the sheets stacked on the stack tray 4003 can be taken out, and the operator can transport them to another location. Assume that the user inputs a job execution request set to stack sheets by the large-capacity stacker 200-3a via the operation unit 204. In this case, the control unit 205 conveys the sheet printed by the printing apparatus 100 to the stack path 4001 provided in the large-capacity stacker 200-3a, and discharges and stacks the sheet on the stack tray 4003. The straight path 4002 is a sheet conveyance path for simply conveying sheets to a subsequent apparatus without performing sheet stacking processing using the stack tray 4003 included in the large-capacity stacker 200-3a.

  Further, the sample tray path 4000 is a sheet conveyance path for discharging a sheet to the sample tray 4006. These are used when simplification of taking out the output from the stack tray 4003 when performing an operation requiring confirmation of output. For example, in this case, the control unit 205 causes the sheet printed by the printing apparatus 100 to be discharged to the sample tray 4006 via the sample tray path 4000. A plurality of sheet detection sensors for detecting the sheet conveyance status and jam are provided in each sheet conveyance path of the large capacity stacker 200-3a. The large-capacity stacker 200-3a includes a CPU (not shown), and notifies the control unit 205 of sheet detection information from each sensor via a signal line. The control unit 205 grasps the sheet conveyance status and jam based on the information from the large-capacity stacker 200-3a. When another sheet processing apparatus 200 is connected between the large-capacity stacker 200-3a and the printing apparatus 100, a CPU (not shown) included in the sheet processing apparatus 200 displays the sensor information of the large-capacity stacker. Notify the control unit 205.

  FIG. 5 is a cross-sectional view illustrating the internal configuration of the gluing bookbinding machine 200-3b.

  The gluing bookbinding machine 200-3b selectively conveys the sheet conveyed from the upstream apparatus to three conveyance paths. The three transport paths are a cover path 5000, a body path 5001, and a straight path 5002. The glue binding machine 200-3b has an inserter path 5003. The inserter path 5003 is a sheet conveyance path for conveying a sheet placed on the inserter tray 5004 to the cover path 5000. A straight path 5002 is a sheet conveyance path for conveying a sheet of a job that does not require a gluing bookbinding process by the gluing bookbinding machine 200-3b to a subsequent apparatus. On the other hand, a main body path 5001 and a cover path 5000 are sheet conveyance paths for conveying sheets necessary for producing case-bound printed products. For example, when creating a case binding print using the glue binding machine 200-3b, the control unit 205 causes the printer unit 203 to print text image data to be printed on a text sheet of the case binding print. . Note that the sheet bundle for the text in the case binding process is referred to as “body”. The control unit 205 performs control so that the sheet printed by the printing apparatus 100 serving as the main body is conveyed to the main body path 5001. When performing the case binding process, the control unit 205 executes a process of wrapping the body printed by the printing apparatus 100 with a cover sheet conveyed through the cover path 5000. For example, the control unit 205 sequentially stacks the main sheets conveyed from the upstream apparatus on the stack unit 5005 via the main body path 5001. When the number of sheets corresponding to one volume is stacked in the stack unit 5005 in this way, the control unit 205 conveys one cover sheet required for the job via the cover path 5000. Let Note that the cover sheet may be conveyed from the printing apparatus 100 or may be conveyed from the inserter path 5003 based on an instruction from the user.

  In parallel with this operation, the control unit 205 causes the gluing unit 5006 to perform a gluing process on the back cover of the sheet bundle for one set corresponding to the main body already stacked on the stack unit 5005. Thereafter, the back cover part of the body subjected to the glue binding process and the center part of the cover are joined by the glue part 5006. When the main body is joined to the cover, the main body is conveyed so as to be pushed downward. As a result, the cover is folded so that the body is wrapped with a single cover. Thereafter, the sheet bundle for one set is stacked on the turntable 5008 along the guide 5007.

  After the sheet bundle for one set is set on the turntable 5008, the control unit 205 cuts three ends other than the end corresponding to the spine portion of the sheet bundle for one set. Is executed by the cutter unit 5009. Specifically, the control unit 205 rotates the sheet bundle by 90 degrees using the turntable 5008 every time one edge cutting process is executed. The three-side cutting process is completed by performing the cutting process for one end portion three times in total. Thereafter, the control unit 205 pushes the sheet bundle that has been subjected to the three-way cutting process in the direction of the basket 5011 using the width-shifting unit 5010 and stores the sheet bundle in the basket 5011.

  FIG. 6 is a cross-sectional view illustrating the configuration of the saddle stitch binding machine 200-3c.

  The saddle stitch bookbinding machine 200-3c selectively executes a staple process, a cutting process, a punch process, a folding process, a shift paper discharge process, a saddle stitch bookbinding process, and the like on a sheet printed by the printing apparatus 100. With units. The saddle stitch bookbinding machine 200-3c does not have a straight path serving as a sheet conveying function to the subsequent apparatus. Therefore, when connecting a plurality of sheet processing apparatuses to the printing apparatus 100, the saddle stitch binding machine is connected at the end as shown in FIG.

  This saddle stitch binding machine 200-3c has a sample tray 6000 and a stack tray 6001 outside the apparatus, and a booklet tray 6002 inside the apparatus. When the control unit 205 receives an instruction to staple with the saddle stitch binding machine 200-3c, the control unit 205 sequentially stacks the sheets printed by the printing apparatus 100 on the processing tray 6003 inside the apparatus. When a bundle of sheets is stacked on the processing tray 6003 in this way, the control unit 205 executes stapling with the stapler 6004. Thereafter, the control unit 205 discharges the stapled sheet bundle from the processing tray 6003 to the stack tray 6001.

  Further, when executing a job instructed to perform Z-folding by the saddle stitch binding machine 200-3c, the control unit 205 causes the Z-folding unit 6005 to form a Z-shape on a sheet printed by the printing apparatus 100. Execute the folding process. Then, the control unit 205 controls the folded sheet to pass through the saddle stitch binding machine 200-3c and be discharged onto a discharge tray such as the stack tray 6001 and the sample tray 6000.

  When the saddle stitch binding machine 200-3c is instructed to set punch processing, the control unit 205 executes punch processing by the puncher unit 6006 on a sheet printed by the printing apparatus 100. Then, the control unit 205 controls the sheet to pass through the saddle stitch binding machine 200-3c and discharge it to a discharge tray such as the stack tray 6001 and the sample tray 6000.

  Further, when executing a job for which the saddle stitch bookbinding machine 200-3c has received an instruction to perform the saddle stitch bookbinding process, the control unit 205 includes a plurality of sheets for one set by the saddle stitcher unit 6007. Two-point binding is performed at the center of the sheet bundle. Thereafter, the control unit 205 causes the roller to bite the central portion of the sheet bundle, thereby causing the sheet to be folded in half based on the central portion of the sheet. Thereby, a booklet like a pamphlet can be created. In this way, the sheet bundle that has undergone saddle stitch binding processing in the saddle stitcher unit 6007 is conveyed to the booklet tray 6002.

  When an instruction to perform the cutting process is received for a job that has been instructed to perform the saddle stitch bookbinding process, the control unit 205 removes the sheet bundle that has been saddle stitched from the booklet tray 6002. It is conveyed to 6008. Thereafter, the control unit 205 causes the cutter unit 6009 to cut the sheet bundle conveyed to the trimmer 6008 and causes the booklet hold unit 6010 to hold the sheet bundle. This saddle stitch bookbinding machine 200-3c is also configured to be able to execute the three-sided cutting process for the saddle stitched sheet bundle.

  When the saddle stitch bookbinding machine 200-3c does not have the trimmer 6008, the sheet bundle bound by the saddle stitcher unit 6007 can be taken out from the booklet tray 6002. Further, the saddle stitch binding machine 200-3c may attach a sheet (for example, a pre-printed cover sheet) set on the insert tray 6011 to a sheet printed by the printing apparatus 100 conveyed from the printing apparatus 100. It is configured to be able to.

  Next, the configuration of the operation unit 204 will be described with reference to FIG.

  FIG. 7 is an external view of the operation unit 204 of the printing apparatus 100 according to the present embodiment.

  The operation unit 204 includes a touch panel unit 401 and a key input unit 402. The touch panel unit 401 includes a liquid crystal display unit and a transparent electrode pasted thereon, and displays various setting screens for receiving instructions from the user. The touch panel unit 401 has both a function for displaying various screens and an instruction input function for receiving instructions from the user. The key input unit 402 includes a power key 501, a start key 503, a stop key 502, a user mode key 505, and a numeric keypad 506. A start key 503 is used to cause the printing apparatus 100 to start a copy job or a transmission job. A numeric keypad 506 is used for setting a numerical input such as the number of copies to be printed. The control unit 205 controls the printing system 1000 to perform various processes based on user instructions received through various screens displayed on the touch panel unit 401 and user instructions received through the key input unit 402.

  FIG. 8 is a diagram illustrating an example of a setting screen for the user to select the type of sheet processing to be executed on a sheet printed by the printing apparatus 100 according to the present embodiment.

  The control unit 205 causes the touch panel unit 401 to display the screen illustrated in FIG. 8 when a sheet processing setting key (FIG. 7) on the screen displayed on the touch panel unit 401 is instructed by the user. This screen is a setting screen configured so that the user can select the type of sheet processing that can be executed using the sheet processing apparatus 200 present in the printing system 1000. The control unit 205 receives a sheet processing setting to be executed in the job to be processed from the user via the setting screen, and causes the sheet processing apparatus 200 to execute the sheet processing according to the setting.

  FIG. 9 is a diagram showing an example of a system management setting screen displayed on the operation unit.

  This is because when the sheet processing apparatus 200 is connected to the printing apparatus 100, the user registers information for specifying what kind of sheet processing apparatus is connected in what connection order and how many. It is a setting screen. When the user mode key 505 is instructed, the control unit 205 displays the screen in FIG. 9 on the touch panel unit 401. Now, for example, a case where the printing system 1000 according to the present embodiment has a system configuration as shown in FIG. 3 will be described. In this case, as shown in FIG. 9, three sheet processing apparatuses of “large capacity stacker”, “glue binding machine”, and “saddle binding machine” are connected to the printing apparatus 100 in order from the large capacity stacker. Set the registration information shown. The control unit 205 stores information related to the sheet processing apparatus 200 set by the user via the setting screen in the RAM 208 as system configuration information, and appropriately reads and references the information. As a result, the control unit 205 can recognize what kind of sheet processing apparatus capable of executing what kind of sheet processing is connected to the printing apparatus 100 in what connection order.

  In FIG. 9, it is assumed that the saddle stitch binding machine 200-3c having no straight path is set to be connected in the middle of a plurality of sheet processing apparatuses 200. In this case, the control unit 205 invalidates the setting and causes the touch panel unit 401 to display an error. Further, as shown in FIG. 9, the control unit 205 displays guidance information for notifying the user that the saddle stitch binding machine 200-3c is connected at the end without performing such setting. May be.

  In this embodiment, the operation unit 204 provided in the printing apparatus 100 is described as an example of a user interface unit applied to the printing system 1000. For example, the printing system 1000 may be configured to execute processing based on an instruction from a user interface unit provided in an external device such as the server PC 103 or the client PC 103.

  FIG. 10 is a diagram illustrating an example of a setting screen displayed on the display unit of the external apparatus when the printing system 1000 is remotely operated from the external apparatus. Here, the case of the client PC 104 will be described. Therefore, FIG. 10 is an example of a screen displayed on the display included in the client PC 104.

  When receiving a print request from the user, the CPU included in the client PC 104 displays a screen as shown in FIG. 10 on the display, and accepts the setting of print processing conditions from the user of the PC 104 via this screen. For example, the user can specify the type of sheet processing to be executed by the sheet processing apparatus 200 for a print job requested to be executed from the client PC 104. Thus, when the OK key is instructed, the CPU of the client PC 104 recognizes the sheet processing type item checked in the setting field 1702. As a result, the CPU of the client PC 104 associates the print processing conditions received via this screen with the image data to be printed, and transmits the print data to the printing system 1000 via the network 101 as one print job. As a result, the control unit 205 of the printing system 1000 accepts the print job execution request via the external I / F unit 202 and processes the print job from the client PC 104. As described above, various units can be provided as a user interface of the printing system 1000.

The UI control program 3110 identifies the content input by the user of the printing system 1000 through the operation unit 204 and performs an appropriate screen transition and a processing request instruction to the control unit 205.

  The other control program 3111 realizes a function that does not correspond to any of the above-described programs. The details are not important here, and the description is omitted. The mounting option capability table 3112 is table information that statically holds capability information of devices that can be attached to and detached from the printing system 1000. The capability information is referred to when the control unit 205 of the printing system 1000 executes various jobs and manages the device itself. This is stored in the ROM 207 and is referred to when processing such as changing the processing content according to the capability of the mounting option. The name of this table is a mounting option capability table, but the mounting options are detachable from devices such as a large-capacity stacker 200-3a, a glue binding machine 200-3b, and a saddle stitch binding machine 200-3c. Not limited to devices. For example, the printing apparatus main body 100 and the scanner included in the printing apparatus 100 may be managed in the same table as a special form of the mounting option. In the present exemplary embodiment, information regarding the printing apparatus 100 will be described in the case where management is performed using the same table, as in the case of a removable apparatus.

  FIG. 12 is a diagram illustrating an example of the storage status of various data stored in the HDD 209 and read or written by the control unit 205 of the printing system 1000. The control unit 205 controls to perform various processes using various data stored in the HDD 209.

  Note that the information stored in the HDD 209 is different from the data state of the ROM 207 shown in FIG. 11, and changes dynamically according to the usage status of the device, the device configuration, and the progress of the job. Therefore, the data state shown in FIG. 12 is a diagram showing the data state at a certain point in time when the printing system 1000 is in operation. Therefore, the data state in the ROM 207 is not always the same as that shown in FIG. For example, there may be a case where the empty area shown in FIG.

  The device management information 3301 stores information such as the connection status and status capability of devices that may or may not exist depending on the connection status of the detachable sheet processing apparatus 200 and the optional configuration of the printing system 1000. To do. The device management information 3301 is managed by the device management program 3104. Information stored and managed in the device management information 3301 and how the device management information 3301 is used by the control unit 205 and at what timing are described later with reference to FIGS. To do.

  The processing rule table 3302 describes operation specifications regarding the operation of the device when the printing system 1000 cannot execute the JDF print job according to the settings made for the job due to the device configuration and the device capability. Yes. Information stored in the table 3302 and how the information in the table 3302 is used by the control unit 205 at what timing will be described later with reference to FIG. Job execution control based on the processing rule table 3302 need not be limited to JDF print jobs. For example, processing rule tables for other job types can be defined, and processing can be performed in the same way as for JDF print jobs when other job types are executed. In this embodiment, for convenience of explanation, a case of a JDF print job will be described.

  Saved document data 3303 corresponds to document data held in the printing system 1000 by a BOX function realized by the BOX function program 3109. The saved document data management table 3304 stores management information of the saved document data 3303.

  The spool area 3305 temporarily holds the print target data transmitted to the printing system 1000 until the execution of the job is completed. Such print target data includes data transmitted by the PDL print function realized by the PDL print function program 3107, or data transmitted by the JDF print function realized by the JDF print function program 3108. When the execution of this print job is completed, the corresponding print job data is deleted from the spool area 3305, and the area is released for the subsequent print job. Control of storing data in the spool area 3305 and releasing the area after the job is completed is controlled by the control unit 205 in the course of executing the PDL print function and the JDF print function.

  The free area 3306 corresponds to an area of the HDD 209 other than all the areas described above, and the capacity of this area changes according to the progress of processing of the printing system 1000. Depending on the usage load of the HDD 209, the free space 3306 may disappear.

  FIG. 13 is a diagram showing an example of the configuration of job data processed by the JDF print function implemented by the JDF print function program 3108.

The JDF print job assumes that the following is incorporated into a single package in MIME format and accepts data encoded in MIME format. Note that MIME refers to Multipurpose Internet Mail Extensions.
-Content data corresponding to image information to be printed-Job ticket area holding only job setting information-Management area for performing communication and status management between POD workflows JDF printing according to this embodiment Also in function, job data processing in MIME format is assumed. The JDF specification also mentions handling of job data other than MIME packages. However, since the data packaging specification is not essential in describing the effect of the present embodiment, the case of the MIME format described above will be described. However, it goes without saying that a JDF job may be input in a format other than the MIME format.

  The MIME header 3501 is a header area that is always required when a plurality of parts are incorporated into a single package in the MIME format, and stores MIME management information such as the data size of the entire MIME package. The JMF part 3502 is an area for storing management information for performing communication and status management between the POD workflows described above.

  A JDF part 3503 is an area for holding the above-described job setting information. As to what setting information the JDF job ticket holds in what format, it is described in the JDF specification issued by CIP4 as the JDF specification. In addition, again, CIP4 is an abbreviation for “Cooperation for the Ingegration of Processes in Prepress, Press and Postpress”. When realizing the JDF print function in the printing system 1000, it is assumed that processing is performed based on the items described in this specification, and thus detailed description thereof is omitted. However, in order to illustrate a minimum specific example in explaining the effect according to the present embodiment, a specific example of a job ticket will be shown in the following figure and an outline description will be given.

  A PDL file 3504, a PDL file 3505, and a PDL file 3506 are content data to be printed. In the figure, three pieces of content data are included in the MIME package. There is no limitation on the number of PDL contents. Further, according to the JDF specification, the PDL content may be held in an external file system or the like instead of being included in the MIME package, and only the URL of the held file may be described in the JDF. In this case, the printing system 1000 processes content data by pulling a file held in an external file system or the like based on this URL. However, since the basic operation is the same as the case where PDL content is included in MIME, in this embodiment, detailed description of the operation during PULL of the content file is omitted. Note that the specifications of the MIME format itself are defined in RFC (Request for Comments), and thus detailed description thereof is omitted here.

  FIG. 14 shows a specific example of the JDF description contents of the JDF part 3503 included in the MIME package according to the embodiment. This figure is only a specific example of JDF description based on the JDF specification, and it is obvious that the present invention is not limited to this.

The JDF part shown in FIG. 14 is roughly composed of the following four parts.
A JDF node 3701 in which JDF management information is stored
Audit pool 3702 for storing job history
-Resource link pool 3703 describing the relationship between resources and processes defined by JDF
A resource pool 3704 that stores setting information in the process defined by JDF
The specific specification of each part, the described contents, the schema, and the like may be any as long as they conform to the JDF specification. Since the JDF specification is described in the JDF specification, it is not mentioned in the description of the present embodiment.

  FIG. 15 is a diagram showing a specific example of information stored and managed in the mounting option capability table 3112 according to the present embodiment. The mounting option capability table 3112 is included in the device management information 3301.

  The mounting option capability table 3112 includes four fields 3901 to 3904, and information on these four fields is managed and stored for each connected device.

  The device type field 3901 is a field for identifying the type of removable device such as the sheet processing apparatus 200 that can be mounted on the printing system 1000 and the paper deck 319 (FIG. 3). Note that in the present embodiment, the printing apparatus 100 is regarded as a special mounting option and managed in the same table for the reason of management operation by being managed in a single table. If it is necessary to strictly identify and manage the mounting option and the printing apparatus 100, the table shown in FIG. 15 may be divided into two and managed. Hereinafter, in the description of FIG. 15, the removable device and the printing apparatus main body 100 are collectively referred to as a device.

The category field 3902 stores the category to which the device stored in the device type field 3901 belongs. As the categories stored here, for example, the following can be defined, and one of the categories is stored in the category field 3902.
・ "Printing device" capable of printing on paper
・ Deck only for stocking media to be printed
・ "Stacker" that can hold a large amount of printed media
・ Finisher that can process various output paper such as folding, binding, punching, etc.
In addition, there is an apparatus capable of supplying paper alone without providing a deck with a paper feed opening in the printing apparatus 100. For example, the printing system 1000 according to the present embodiment includes paper cassettes 317 and 318 as shown in FIG. 3, and can feed paper alone. Even in such a device, from the viewpoint of management of the table, the device is classified as a printing apparatus without being classified as a deck. In other words, the mounting option capability table 3112 is managed so that each device always falls into one of the four types of categories described above.

  The function field 3903 stores types of various functions included in the device. Since the supported functions differ depending on the category type to which the device belongs, the inside of the table in FIG. That is, the mounting option capability table 3112 is managed so that devices belonging to the same category have the same type of function fields.

  The support status 3904 holds flag information indicating whether or not the function described in each function field 3903 of each device can be realized. The function field 3903 stores a value (eg, code) indicating “OK” when the device supports the function, and indicates “NG” when the device does not support the function. Stores the value.

  The mounting option capability table 3112 stores information on five types of devices. The five types of devices are five types: a multifunction machine main body, a large capacity paper deck, a large capacity stacker 200-3a, a gluing bookbinding machine 200-3b, and a saddle stitch bookbinding machine 200-3c. Of these, the gluing bookbinding machine 200-3b and the saddle stitch bookbinding machine 200-3c belong to the same category of finishers.

  FIG. 16 is a diagram for explaining the contents of the device configuration management table according to the present embodiment.

  This device configuration management table is managed by the device management function program 3104, and is held in the RAM 208 according to the method and conditions made in the description of the device management function program 3104. This device configuration management table manages the connection status of the removable sheet processing apparatus 200, the paper deck 319 (FIG. 3), or the sub-devices constituting the printing apparatus 100, which are mounted on the printing system 1000. The device configuration management table includes three fields 4101 to 4103. Hereinafter, these three fields will be described.

  A device name field 4101 lists all devices that can be attached to and detached from the printing system 1000. When multiple devices of the same type can be mounted, the device name is managed by adding a number to the end. The printing system 1000 can select a combination of device configuration management tables according to user needs. However, not all combinations are possible depending on the types of devices to be combined. However, the device name field 4101 of the device configuration management table does not manage the validity of these combinations, and lists all devices that may be attached to the device. Whether or not it is actually mounted is identified by the value of another field (connection status field 4103) in the table described later.

  The device type field 4102 stores the category of the device stored in the device name field 4101. Here, a value equivalent to the content of the category field 3902 of the mounting option capability table 3112 is stored.

  The connection status field 4103 stores data indicating whether the device described in the device name field 4101 is actually connected to the printing apparatus 100. Here, when the device described in the device name field 4101 is connected to the printing apparatus 100, data indicating “OK” is stored. On the other hand, when the device described in the device name field 4101 is not connected to the printing apparatus 100, data indicating “NG” is stored. In the example of the table in FIG. 16, the printing system 1000 indicates that the scanner unit 201 and one large-capacity stacker 200-3a are connected.

  FIG. 17 is a diagram illustrating an example of detailed contents of information stored in the processing rule table 3302 (FIG. 12) according to the embodiment.

  The processing rule table 3302 includes three fields 4301 to 4303. Hereinafter, these three fields will be described. The function field 4301 stores a setting attribute type (corresponding to a processing condition instructed to the job) for a function that can be set by the JDF job ticket and is necessary at the time of job execution. In FIG. 17, 16 different setting items are registered. The number of setting item types that can be processed by an actual JDF print job is greater than the number shown in FIG. 17 and is not limited to this embodiment.

The unsupported operation specification field 4302 describes processing contents to be adopted when the control unit 205 executes the JDF print job input to the device when the printing system 1000 cannot execute the designated function. ing. In the operation specification field 4302 when not supported, operation designation information for designating an operation to be performed when the printing apparatus 100 cannot provide a printing function necessary for satisfying the condition information indicating the designated printing condition for each printing function. A value corresponding to is stored. There are the following three types of values that the field 4302 can take.
“Operation with default value”: Indicates that when the target function cannot be executed, the job ticket is changed to the default value set to the default value 4303 for the function and the job is executed.
“Ignore”: indicates that if the target function cannot be executed, the job is executed assuming that the setting for the function by the job ticket was not originally made.
“Cancel”: indicates that, when the target function cannot be executed, the execution of the job by the job ticket in which the setting related to the function is set is invalidated.

  In this embodiment, it is assumed that the value of the non-supporting operation specification field 4302 corresponding to each function described in the function field 4301 is preset in the system. However, the value of this field 4302 may be changeable by the user. In that case, the user changes the value of the field 4302 by operating from the operation unit 204.

  The default value field 4303 stores a default value selected when the value of the operation specification field 4302 at the time of non-support is “operation by default value”. Therefore, when the value of the operation specification field 4302 at the time of non-support is other than “operation by default value”, the value of this field 4303 is null (null). When the target function cannot be executed by the printing system 1000, the control unit 205 can execute the job without canceling the job by performing a default value operation as an alternative. For example, according to the processing rule table 3202 shown in FIG. 17, when a request for executing a job instructed to perform double-sided printing is received, but the double-sided printing function is not provided in the printing system 1000, the following is performed. To control. The control unit 205 changes the duplex printing setting of the job instructed to perform duplex printing to the simplex printing setting according to the processing rule table 3202, and executes the simplex printing when the job is executed.

  18 is a diagram for explaining the details of the JDF analysis result table generated after the completion of the analysis of the JDF part 3503 of the job ticket shown in FIG. 13 when the JDF print job by the job ticket shown in FIG. 13 is input. It is. The JDF print job is input via the external I / F 202 based on the JDF print function program 3108 stored in the HDD 209 executed by the control unit 205, for example. This JDF analysis result table is composed of three fields 4501 to 4503. Hereinafter, these three fields will be described.

The function field 4501 stores the type of setting attribute for each function that is determined as a result of analyzing the JDF job ticket. This type of setting attribute can be said to be a condition for processing a job instructed to be executed for a JDF print job. The analysis result field 4502 stores the result of analyzing the JDF job ticket according to the type of the function field 4501. Executability field 4503 stores the result of collating the analysis result for each function by the control unit 205 with the field of the corresponding function in the processing rule table of FIG. For example, the control unit 205 compares the analysis result for each function with the value of the operation specification field 4302 of the processing rule table, and stores the result of determining for each setting item whether or not to continue the JDF print job. . The value is stored in the execution availability field 4503 after the JDF part analysis processing is completed. The analysis result for each function is stored in, for example, the analysis result field 4502, and the processing rule table is illustrated in FIG. There are the following three types of values that can be taken by the execution availability field 4503.
“OK”: Indicates that the job can be continuously processed as a result of the comparison of the JDF part analysis result in a certain function and the operation specification field when the function is not supported in the processing rule table shown in FIG. The control unit 205 recognizes the function set for the job, and refers to the function column of the processing rule table 3302 corresponding to the recognized function. In the processing rule table 3202, when the value of the operation specification 4302 at the time of non-support set for the function is set to “operate with default value” or “ignore”, the control unit 205 The execution propriety field 4503 is set to “OK”. Even when the printing system 1000 supports the function, the control unit 205 sets the execution field 4503 of the function to “OK”.
“NG”: As a result of the comparison with the analysis result of the JDF part in a certain function and the operation specification field when the same function is not supported in the processing rule table shown in FIG. 17, the job cannot be continuously processed. Indicates that cancellation is required. The control unit 205 recognizes the function set for the job, and refers to the function column of the processing rule table 3302 corresponding to the recognized function. In the processing rule table 3202, when the value of the unsupported operation specification 4302 set for the function is set to “job cancel”, the control unit 205 sets the execution possibility field of the function to “NG”. "
“N / A”: indicates that the setting of the function is not originally set or the job is not related to the determination of whether or not the job can be continued, for example, when the printing system 1000 originally does not support it.

  A case where the job is analyzed as shown in FIG. 18 will be described as an example. The example illustrated in FIG. 18 is a JDF analysis result table generated when the JDF job ticket illustrated in FIG. 14 is analyzed when the device configuration management table included in the printing system 1000 is in the state illustrated in FIG. It is. In the job ticket of FIG. 14, execution of the center folding bookbinding process by saddle stitch is instructed. However, according to the device configuration management table shown in FIG. 16, a finisher capable of executing the center folding bookbinding process is mounted. Not. Here, in FIG. 17, the operation specification field 4302 when the saddle stitch binding function of the processing rule table 3302 is not supported is referred to. In this case, since “job cancel” is set, the value of the execution field of the saddle stitch binding function in FIG. 18 is “NG”. That is, the JDF print job including the JDF job ticket illustrated in FIG. 14 is canceled without being executed when the configuration and state of the printing system 1000 are those shown in FIG.

(Basic processing)
Next, the operation of the printing system 1000 according to the present embodiment based on the control of the control unit 205 will be described.

  FIG. 19 is a flowchart illustrating processing related to control of the entire device as a multifunction peripheral after the system is started by the control unit 205 of the printing apparatus according to the present embodiment. A program for executing this process is stored in the ROM 207 and executed under the control of the control unit 205.

  This process is started when the power is turned on. First, in step S1, a boot process is performed. Specifically, this corresponds to the control unit 205 reading the boot loader 3101 shown in FIG. 11 from the ROM 207 and executing the read program. The processing performed in step S1 includes all initialization processing corresponding to initialization processing such as issuance of initialization commands to various devices and resources connected to the printing system, and cleaning performed immediately after the device is started. Execution is included. The processing performed by the boot loader 3101 includes a process from when the control unit 205 reads the operating system 3102 (FIG. 11) from the HDD 209 until the service of the operating system is started.

  When the boot process is thus completed, the process proceeds to step S 2, and the control unit 205 reads and executes the device management function program 3104 stored in the ROM 207. In this case, the device management function program 3104 causes the control unit 205 to check the device connection state and create a device configuration management table (FIG. 16) in the RAM 208. Details of the operation in this step will be described later with reference to FIG.

In step S3, the control unit 205 reads a program other than those described above from the ROM 207 and executes it. In this step S3, the programs to be loaded include all of the various programs stored in the ROM 207 shown in FIG. 11 except those already read in the above steps. Omitted. When steps up to step S3 are executed in this way, the preparation for functioning as a multifunction device of the printing system 1000 is completed, and the process shifts to an event waiting state in step S4. For example, the following events are included in the event.
An event when the user operates the operation unit 204 to give a job execution instruction or change a setting.
An event by a print job input to the printing system 1000 from a device outside the printing system 1000 via the external I / F 202.
An event due to reception of a JDF print job and an execution request for the received job.
A processing request other than job input to the printing system 1000 from a device outside the printing system 1000. For example, events due to device status acquisition or changes in various setting information and management information stored in the device.
Various events that occur inside the printing system 1000 Specifically, an event caused by all the events that trigger the printing system 1000 to transition from the idle state, such as when the paper runs out or when the device status changes.

  In step S4, the control unit 205 does not transition the process to step S5 unless an event occurs.

  If some event occurs in the printing system 1000 in step S4 and the event is notified to the control unit 205, the process proceeds to step S5 and subsequent steps. Then, identification of the generated event and an operation corresponding to the generated event are executed. Therefore, first, in step S5, the control unit 205 determines the type of the event that has occurred in step S4.

  Next, the process proceeds to step S6, and as a result of determining the event in step S5, it is determined whether or not the generated event is a JDF job execution start request. The JDF job execution start request is an event issued to the control unit 205 when it is determined that the external I / F 202 has received JDF job data from an external device. As a result of the determination in step S6, if it is determined that the generated event is a JDF job execution start request, the process proceeds to step S9. In step S <b> 9, the control unit 205 executes print processing of a JDF print job input to the printing system 1000 from a device outside the printing system 1000 via the external I / F 202. Details of the processing in step S9 will be described later with reference to FIG.

  On the other hand, if it is determined in step S6 that the generated event is not a JDF job execution start request, the process proceeds to step S7, and the control unit 205 determines whether the generated event is due to a device configuration change. If it is determined that the event that occurred is a device configuration change, the process proceeds to step S10, and device configuration change processing is executed. Details of the device configuration change processing will be described later with reference to FIG.

  On the other hand, as a result of the determination in step S7, if it is determined that the request is neither a JDF job execution start request nor a device configuration change process, the process proceeds to step S8, and processing other than the JDF job execution or device configuration change process is performed according to the type of event that has occurred. Execute. There are various contents of the processing executed here, but the types of the individual operations and the details of the operations are not important in explaining the present embodiment. Therefore, they are written together in a single step. However, in step S8, it is specified that execution of a plurality of processes is included as described above.

  When the processing of step S8, step S9, and step S10 by the control unit 205 is completed in this way, the process moves to step S4, and the control unit 205 again enters a waiting state for the next event processing.

(Equipment configuration management)
FIG. 20 is a flowchart illustrating the detailed operation of the device configuration management program in step S2 (FIG. 19) executed by the control unit 205 of the printing apparatus 100 according to this embodiment.

  First, in step S21, an entry of the device configuration management table is created in the RAM 208. The device configuration management table has been described with reference to FIG. In the device configuration management table created here, data is stored only in the device name field 4101 and the device type field 4102, and the connection status field 4103 is empty. The value of this connection status field 4103 is determined in subsequent processing. In step S22, it is determined whether or not the investigation has been completed for all devices registered in the device name field 4101 existing in the device configuration management table. If there is still a device to be investigated as a result of the determination in step S22, the process proceeds to step S23, and an inquiry target device is selected. The selection order of devices selected at this time is the order of the device name field 4101 of the device configuration management table created in step S21.

  In step S24, it is determined whether the device selected in step S23 is connected to the printing system 1000. The determination process executed at this time is executed in accordance with a specific protocol via connection means for electrically connecting the devices. In step S24, for example, if there is an inquiry target device, the status is returned to the control unit 205 to confirm the connection. On the other hand, if an inquiry request is output and a timeout occurs without a response within a certain period, the inquiry target device is considered to be in a disconnected state. Next, it progresses to step S25 and the inquiry result of step S24 is discriminate | determined. If it is determined that the inquiry target device is connected, the process proceeds to step S26, and the status of the device connection status field 4103 in the device configuration management table is updated to “OK”. On the other hand, as a result of the determination in step S25, if it is determined that the inquiry target device is not connected, the process proceeds to step S27, and the status of the connection status field 4103 of the corresponding device in the device configuration management table is updated to “NG”.

  When the process of step S26 or step S27 is completed in this way, the process returns to step S22 again to investigate the next device. Steps S22 to S26 and S27 form a loop, and the above steps are repeatedly executed until the investigation of all devices described in the device name field 4101 stored in the device configuration management table is completed. If it is determined in step S22 that the investigation of the connection status of all devices has been completed, this processing flow ends.

(Printing process of JDF print job)
FIG. 21 is a flowchart for explaining details of the process executed by the control unit 205 in step S9 of FIG. 19, that is, the printing process of the JDF print job input to the printing system 1000.

  First, in step S31, the MIME format of data constituting the JDF print job is analyzed. Specifically, the content included in the received MIME data is extracted based on the information in the MIME header, and the extracted content data is stored in the HDD 209. Here, there are three types of content cut out from MIME data: JMF, JDF, and PDL content to be printed, and one or more PDL content is allowed to exist.

  Next, the process proceeds to step S32, and the JMF part extracted from the MIME data and stored in the HDD 209 in step S31 is analyzed. The JMF itself plays an important role mainly in charge of communication, status, etc. in controlling the JDF workflow system, but is not important as far as the effects of the present embodiment are described, and thus detailed description thereof is omitted.

  When the analysis process of the JMF part is completed in step S32, the process proceeds to step S33, and the analysis process of the JDF part cut out from the MIME data and stored in the HDD 209 is performed in step S31. Detailed processing in step S33 will be described later with reference to FIG. In this manner, the JDF analysis processing in step S33 also determines whether or not the received job can be executed based on the setting information stored in the job ticket and the device capability and status.

  Next, the process proceeds to step S34, where it is determined whether or not the received job can be executed based on the setting information stored in the job ticket determined in step S33 and the capability and status of the device, and subsequent processing is determined. That is, if it is determined in step S34 that the received job can be executed, the process proceeds to step S35. On the other hand, if it is determined in step S34 that the received job cannot be executed, the process proceeds to step S37. In step S35, the PDL content that is cut out from the MIME data in step S31 and is to be printed is analyzed. Specifically, the PDL command analysis and the conversion processing to image data are executed according to the setting information described in the JDF analyzed in step S33. Finally, it is converted into a printable raster image and stored in the HDD 209. The details of the PDL data analysis processing are not the main part of the present embodiment, and thus the description thereof is omitted.

  In step S36, the print target image data developed in step S35 and stored in the HDD 209 is printed according to the setting information described in the JDF analyzed in step S33. That is, the printing process is performed based on the JDF analysis result table illustrated in FIG. Accordingly, as a result of this analysis, among the printing functions necessary to satisfy the printing conditions specified in the JDF, those that can be provided by the printing system 1000 as specified are executed by the printing function. For those that cannot be provided as specified, an operation based on the operation specification 4302 (FIG. 17) when not supported is executed. Therefore, according to the configuration according to the present embodiment, it is possible to execute an appropriate print process within the range of functions that the printing system 1000 can provide. When the process of step S36 is thus completed, the process returns to step S4 of FIG.

  On the other hand, if it is determined in step S34 that the received job cannot be executed, the execution of the job is canceled in step S37. Then, when the process of step S37 ends, the process returns to step S4 (FIG. 19).

(JDF part analysis processing)
FIG. 22 is a flowchart illustrating details of the JDF part analysis processing in step S33 of FIG.

  First, in step S41, XML parsing processing is performed, and element and attribute information described in the JDF are taken into the internal data structure. Next, in step S42 and subsequent steps, semantic analysis processing is executed based on the information obtained as a result of analysis in step S41. In step S42, the semantic analysis process of the JDF node portion which is the root node of the JDF is executed. In addition to information necessary for job management, the JDF node stores information related to the definition of processes to be processed by the JDF. In step S43, a semantic analysis process is performed on the resource pool information that is the storage location of the setting parameter at the time of job execution in the JDF. This resource pool stores various setting information to be reflected in actual PDL development processing, image processing processing such as imposition, printing processing, finishing processing, and the like.

  In step S44, it is checked whether the link information of the JDF process and the resource is appropriately expressed and inconsistent link setting is not performed. Steps S41 to S44 correspond to the syntax analysis and semantic analysis processing in the JDF part. When the process of step S44 is completed in this way, the process proceeds to step S45, and it is determined whether or not an analysis error has occurred in the processes from step S41 to step S44 described above. If it is determined that an analysis error has occurred, the job cannot be executed, and the process advances to step S47 to set NG to the job execution flag. The job execution flag is stored in a specific area secured in the RAM 208 when the control unit 205 executes the program for performing the process described in the flowchart.

  On the other hand, if it is determined in step S45 that no analysis error has occurred, the process proceeds to step S46 to create a JDF analysis result table. The details of the JDF analysis result table have been described with reference to FIG. 18 described above, and thus the description thereof is omitted here. When the process of step S46 is completed, the process proceeds to step S48, where the analysis result table created in step S46 is collated with the information in the mounting option capability table (FIG. 15). Then, regarding the job settings stored in the analysis result table, the functions that cannot be executed in the configuration of the printing system 1000 at the present time are extracted from the functions described in the mounting option capability table.

  Next, the process proceeds to step S49, and each function that is extracted in step S48 and cannot be executed with the current configuration of the printing system 1000 is collated with the corresponding function column in the processing rule table shown in FIG. As a result, the operation specifications for each setting item that cannot be executed are investigated. Next, the process proceeds to step S50, and the processing rule table (FIG. 17) corresponding to the function extracted in step S48 is referred to based on the investigation result in step S49. Here, it is determined whether or not the value of the operation specification field 4302 when the function is not supported is job cancel. In this way, if it is determined that there is a job setting that cannot be executed depending on the device configuration or capability, and that one of the functions set to cancel the job exists when the function is set, step S50 to step S50 are performed. Proceed to S47. In step S47, the job is canceled.

  On the other hand, if the determination result in step S50 is false, even if there is a job setting that cannot be executed due to the device configuration or capability, there is no need to cancel the job by that setting. That is, it corresponds to a case where job execution can be continued by selecting a default value according to the contents of the processing rule table or ignoring the setting itself. In this case, the process proceeds to step S51, the contents of the JDF analysis result table (FIG. 18) are corrected according to the contents of the processing rule table, the process proceeds to step S52, and OK is set in the job execution flag.

(Device configuration change processing)
FIG. 23 is a flowchart for explaining the details of the correction processing of the device configuration management table (FIG. 16) when the device configuration is changed after step S10 of FIG.

  As a result of the determination in step S61, if there are still devices to be investigated, the process proceeds to step S62, and an inquiry target device is selected. At this time, the devices are selected in the order of the device name field 4101 stored in the device configuration management table of FIG. In step S63, it is determined whether the device selected in step S62 is connected to the printing system 1000. In the determination processing executed at this time, the connection status is confirmed according to a specific protocol via connection means for electrically connecting the devices, but detailed description thereof is omitted. If there is an inquiry target device, the status is returned to the control unit 205 to confirm the connection. On the other hand, if an inquiry request is output but no response is received within a certain period of time and a timeout occurs, the inquiry target device is regarded as being in a disconnected state. In step S64, the inquiry result in step S63 is determined. If it is determined that the inquiry target device is connected, the process proceeds to step S65, and the status of the connection status field 4103 of the corresponding device in the device configuration management table (FIG. 16) is displayed. Update to “OK”. On the other hand, if it is determined in step S64 that the inquiry target device is not connected, the process proceeds to step S66, and the status of the connection status field 4103 of the corresponding device in the device configuration management table is updated to “NG”.

  After the process of step S65 or step S66 is completed, the process returns to step S61 again to investigate the next device. Steps S61 to S65 and S66 form a loop, and the above steps are repeatedly executed until the investigation of all devices described in the device name field 4101 stored in the device configuration management table is completed. If it is determined in step S61 that the investigation of the connection status of all devices has been completed, this flow ends.

  According to the configuration according to the present embodiment, it is possible to construct a convenient printing environment that is easy to use and can be applied not only to the office environment but also to the POD environment. Further, for example, it is possible to cope with the needs of an actual work site in a printing environment such as POD, such as the need to operate the system with high productivity and the need to reduce the operator's work load. In particular, the following effects are exhibited.

  Consider a case in which an instruction relating to the entire printing process is given by print data including a JDF job ticket, which is currently being supported as a printing apparatus for the POD market. In this case, it is possible to deal with a case where an instruction related to a series of work processes in which a plurality of devices cooperate with each other is described in addition to a single process from a submission process to a delivery process related to a printed product as a final product. That is, a series of workflows composed of a plurality of processes using a plurality of devices can be managed with one instruction sheet. As a result, there are advantages in terms of cooperation between a plurality of devices related to the overall printing process and automation of various devices.

  This is effective when building a printing system that can process jobs with various devices in a common format that does not depend on a single device. For example, when JDF is supported in a digital multi-function peripheral, unlike a conventional printer driver, it may be possible to receive a JDF job ticket created without knowing device specifications and configuration information and execute print processing or the like. For example, consider a case where a user instructs job processing using a job ticket. Even if the user instructs the printing apparatus (printing system) to process the job using the job ticket, the processing instructed by the execution environment (capability of the printing apparatus, mounting accessory, etc.) is completely performed by the printing apparatus (printing system). It may not be possible to execute. In that case, the user may desire to cancel the processing of the job itself. Alternatively, there is a case where it is desired to output a printed matter by a printing apparatus (printing system) even if the setting is not partially reflected. However, JDF format data is versatile and can be expected in terms of device automation, device cooperation, device management, etc., but it is prepared only for one device or a specific type of device. It is not data. For this reason, the conventional system has a problem that the output result intended by the user as described above cannot be determined by the device alone.

  On the other hand, in the printing system according to the present embodiment, can JDF format data created using the XML language included in the input job be analyzed, and print processing that satisfies the conditions indicated by this can be executed? Judge whether or not. If it is determined that the job can be executed, the printing process is performed based on an instruction given to the input job. On the other hand, if it is determined that the job cannot be executed, the printing process based on the instruction given to the job is canceled. Therefore, according to the configuration according to the present embodiment, the printing system 1000 can appropriately control the processing regardless of whether the printing processing can be performed based on the JDF format data included in the input job. Therefore, according to the configuration according to the present embodiment, in a printing system that operates based on a print job in which conditions are described in a general-purpose format, it is possible to perform an appropriate print process by eliminating extra user effort. Technology is provided.

  In this way, it is possible to provide a printing system that can flexibly cope with various user needs. As described above, it is possible to construct a convenient and flexible printing environment that can cope with use cases and needs that can be assumed in the POD environment, and it is possible to provide various mechanisms for commercializing the product.

  In the above configuration, if the print function is necessary to satisfy the print condition indicated by the JDF included in the print job and “job cancel” is not specified for all unsupported print functions, The control unit 205 does not cancel the job. Instead, the control unit 205 executes the process with the alternative function when the process can be performed with the alternative function. When the process is executed with the alternative function, log information (log file) indicating the result of the printing process is stored in a predetermined storage device (HD, RAM, etc.). And according to the instruction | indication from a user, log recording information can be displayed on a display means. According to such a configuration, the user can know what print processing has actually been performed when the print processing is performed using a print function different from the print job setting.

  If it is determined that the job cannot be executed, it is possible to display a print condition that cannot be executed on the display unit and change the print condition in accordance with an instruction from the user to perform the printing process. . According to such a configuration, the user can execute the printing process by changing the printing conditions in accordance with the function that the printing system can provide.

  When it is determined that the print process cannot be executed and the job cancel process is executed, the print job may be stored in a storage device (job storage unit) such as an HDD. Thereby, it is possible to read the print job from the storage device later and perform the printing process again.

  Further, the display unit controls the display of the print condition of the canceled print job stored in the storage device, changes the print condition in accordance with an instruction from the user (changes the print condition), and stores the stored print job. The printing process may be performed based on the above. As a result, it is possible to read the stored print job in accordance with a user instruction, update the printing conditions as appropriate, and execute an appropriate print process.

[Embodiment 2]
In the second embodiment, a configuration in which the user can change the contents of the processing rule table (FIG. 17) will be described in detail. Since the system configuration according to the second embodiment is substantially the same as the configuration according to the first embodiment, the same configuration is referred to by the same reference numeral, and the difference will be mainly described.

  FIG. 24 shows an example of a system setting screen displayed on the touch panel unit 401 immediately after the user mode key 505 (FIG. 7) of the operation unit 204 of the printing apparatus 100 is pressed in the printing system 1000 according to the second embodiment. FIG. As shown in the figure, buttons corresponding to various system setting functions are displayed on the touch panel unit 401. Here, the role of the JDF setting button 6101 among the plurality of system setting function buttons will be described. The JDF setting button 6101 is used to display an operation screen for performing settings related to the operation of the JDF print job provided by the printing system 1000. An example of the JDF setting screen displayed on the touch panel unit 401 immediately after the JDF setting button 6101 is pressed is shown in FIG.

The JDF setting screen in the printing system 1000 according to the second embodiment has a function that allows the user to select an operation when the setting items described in the JDF job ticket cannot be executed due to the device configuration, capability, and the like of the printing system 1000. It is to provide. The following two types of modes can be selected by the user on this screen.
A mode in which the job is canceled when the setting items described in the JDF job ticket associated with the cancel button 6301 cannot be executed due to the device configuration or capability of the printing system 1000.
If the setting item described in the JDF job ticket that is associated with the ignore button 6302 cannot be executed due to the device configuration, capability, etc. of the printing system 1000, ignore the contents of the corresponding setting item and continue the job execution. mode.

  In the JDF setting screen of FIG. 25, the ignore button 6302 is selected, but when the cancel button 6301 is pressed, the cancel button 6301 is changed to the selected state. These are performed under the control of the control unit 205 of the printing system 1000.

  FIG. 26 is a diagram illustrating an example of information stored in the processing rule table (FIG. 17) modified by the control of the control unit 205 after the ignore button 6302 is selected on the JDF setting screen illustrated in FIG. 25. .

  In FIG. 26, as the behavior when the function described in the function field 4301 cannot be executed due to the device configuration, capability, or the like of the printing system 1000, the value of the operation specification field 4302 when not supported is changed to “ignore”. When the information in the processing rule table is as shown in FIG. 26, when a JDF print job is submitted and a function related to an inexecutable function is specified in the JDF job ticket portion of the job, the corresponding information shown in FIG. Ignores the setting and continues job execution. This is because, as shown in the first embodiment, the job continuation / cancellation processing is performed in accordance with the contents described in the processing rule table.

  An example is given concretely. For example, consider a case where a JDF job ticket including settings such as saddle stitch binding and case binding is received in a state where the sheet processing apparatus 200 is not installed in the printing system 1000. In this case, settings regarding sheet processing that cannot be executed are ignored, and a printed matter in a form in which those settings are not reflected is generated. For example, as shown in FIG. 1, a case where a saddle stitch binding machine 110, a paper folding machine 107, and the like exist in the workflow of a user who introduces the printing system 1000 is considered. In this case, with the operator interposed, the printed matter by the printing system can be installed in the saddle stitch binding machine 110 and the paper folding machine 107 for processing. Accordingly, it is possible to achieve the user's purpose to obtain an output product that has been subjected to saddle stitch binding or case binding as a final output product.

  FIG. 27 is a diagram illustrating information stored in the processing rule table (FIG. 17) corrected by the control of the control unit 205 after the cancel button 6301 is selected on the JDF setting screen of FIG. 25.

  As shown in the figure, as a behavior when the function described in the function field 4301 cannot be executed due to the device configuration, capability, or the like of the printing system 1000, the value of the operation specification field 4302 when not supported is “job cancel”. For example, when the information stored in the processing rule table is in the state shown in FIG. 27, a JDF print job is input to the printing system 1000, and designation regarding a function that cannot be executed in the JDF job ticket portion of the JDF print job is performed. Consider the case where it was made. In this case, as described in the first embodiment, the job continuation and cancellation operation processing is performed according to the contents described in the processing rule table. For this reason, as shown in FIG. 27, when the corresponding setting exists, the execution of the job is canceled.

  As a specific example, consider a case where a JDF job ticket including settings such as saddle stitch binding and case binding is received in a state where the sheet processing apparatus 200 is not installed in the printing system 1000. In this case, if there are settings relating to sheet processing that cannot be executed, the job is canceled so as not to generate an output product. More specifically, for example, in the workflow of a user who introduces the printing system 1000, the case where the saddle stitch binding machine 110, the paper folding machine 107, etc. do not exist, and the printing system 1000 does not include the sheet processing apparatus 200. think of. In this case, when a job instructing saddle stitch binding or case binding is received as a final output product, if the settings are ignored and the job is continued, an output product with a mistake for the user is generated. For this reason, it is possible to suppress such output by canceling the job.

(Basic processing)
FIG. 28 is a flowchart for describing processing by the control unit 205 of the printing system 1000 according to the second embodiment. This flowchart corresponds to the flowchart of FIG. 19 shown in the first embodiment. Here, steps that are the same as those in FIG. 19 are given the same symbols, and descriptions thereof are omitted.

  If it is determined in step S7 that the device configuration has not been changed, the process proceeds to step S71, and it is determined whether or not the content of the processing request (event) generated in step S4 is a processing rule table content change request. The processing rule table content change request is an operation when the function described in the function field 4301 on the JDF setting screen shown in FIG. 25 cannot be executed due to the device configuration, capability, etc. of the printing system 1000 in the second embodiment. This corresponds to the operation selected by the user.

  If it is determined in step S71 that the request is for changing the contents of the processing rule table, the process proceeds to step S72, and the process for changing the contents of the processing rule table is executed. Then, when the process is completed, the state transitions to the event waiting state in step S4. Details of the process in step S72 will be described later with reference to FIG.

  On the other hand, if the determination result in step S71 is false, the process proceeds to step S8 to execute processing according to the type of event that has occurred other than JDF job execution, processing rule table change, or device configuration change processing.

(Processing rule table change (rule information update) processing)
FIG. 29 is a flowchart for explaining the details of the processing rule table change processing in step S72 of FIG.

  First, in step S81, the processing rule table (FIG. 17) stored in the HDD 209 is read into the RAM 208. Next, the value of the processing policy selected by the user on the JDF setting screen shown in FIG. 25, that is, a cancel or ignore value is read in step S82. The value read here is stored in the RAM 208 under the control of the control unit 205 during the operation on the JDF setting screen of FIG. 25, and is realized by reading the value. Next, proceeding to step S83, it is determined whether or not an entry to be investigated (function-specific items such as double-sided printing and page printing) still remains in the processing rule table. If unprocessed entries remain, the process advances to step S84 to select an entry to be processed next in the processing rule table. In step S85, the value read from the RAM 208 in step S82 is written in the operation specification field 4302 (FIG. 17) when the entry selected in step S84 is not supported. In step S86, a value is written in the default value field 4303 (FIG. 17) of the processing rule table.

  In the second embodiment, since the only value that can be written in the operation specification field 4302 at the time of non-support is only “ignore” or “job cancel”, it is necessary to explicitly set the default value. Absent. Therefore, the operation in step S86 in the second embodiment means that the value of the field is written with an initial value or a value expressing the meaning that no value is stored.

  When the process of step S86 is thus completed, the process returns to step S83. The steps from step S83 to step S86 form a loop, and the processes from step S83 to step S86 are repeated until the processing is completed for all entries in the processing rule table. When it is determined in step S83 that the processing for all entries has been completed, the process proceeds to step S87, the modified processing rule table stored in the RAM 208 is written back to the HDD 209, and this processing is terminated.

  As described above, according to the second embodiment, it is possible to accept a change by the user of the processing rule table. For this reason, the user can perform an appropriate print processing setting according to the application and purpose.

  Here, a supplementary description will be given of the configuration common to the configurations according to the first and second embodiments, including the meaning of confirmation.

  The printing apparatus 100 included in the printing system 1000 according to the present embodiment is configured to accept at least two types of jobs as jobs that require printing processing by the printing apparatus 100. For example, the control unit 205 prints “a job in which a series of processing condition data including printing conditions and post-processing conditions at the time of printing by the printer unit 203 is expressed in JDF format” so that the printing apparatus 100 can accept the job. Control system 1000. As described above, the printing system 1000 according to the present embodiment can accept a job in which various instructions and operation instructions are specified by data in JDF format. In the present embodiment, a job corresponding to this is defined as a “JDF job”, for example, and is referred to as a “first type job”.

  The printing system 1000 is configured to be able to specify an instruction including an instruction relating to a printing process by the printing apparatus 100 and an instruction relating to a post-processing by the sheet processing apparatus 200 using the data in the JDF format. In other words, this means that requests for executing various processes by the printing system 1000 are included as commands in the JDF format data. Further, in the present embodiment, an execution request for a process that cannot be executed by the printing system 1000 is configured to accept a job included as a command in the JDF format data. That is, as a series of processing conditions for a job to be processed, JDF format data including both commands for the printing system 1000 and commands not depending on the printing system 1000 can be accepted. In the present embodiment, a job in which various commands are represented by JDF format data that corresponds to a job to be accepted by the printing system 1000 is defined as a “JDF job”.

  Based on the above configuration, it is assumed that a print execution request by the printing apparatus 100 of the printing system 1000 is made by an operator via the UI unit of this embodiment, and the job to be processed is a JDF job. In this way, on the condition that the printing system 1000 has received the JDF job, the control unit 205 executes the control according to the above-described first and second embodiments, and the printing system 1000 can be executed for the JDF job. Control.

  Now, why the printing system 1000 is configured to be able to process such a JDF job in the present embodiment, the reason, and an example of the operation effect will be described.

  In the present embodiment, the following effects are achieved by enabling the processing of the JDF job by the printing system 1000 including the printing apparatus 100. For example, the printing system 1000 performs “pre-printing processing (prepress) corresponding to processing that needs to be executed in a job to be processed prior to printing processing by the printing apparatus 100” such as printing editing processing by the PC 104. After this process, a printing process (press) by the printing apparatus 100 is performed for the job to be processed. Further, after this processing, post processing (post press) is performed for this job by the sheet processing apparatus 200 of the present embodiment defined with reference to FIG. 1, the nearline finisher, or the like. This post-press corresponds to “post-printing processing corresponding to processing that needs to be executed in a job to be processed after printing processing by the printing apparatus 100”.

  The POD system 10000 shown in FIG. 1 executes a series of processes (prepress → press → postpress), which are executed for each of a plurality of independent devices, and a series of workflows (also referred to as job flow) for completing a job. Can be executed. In the present embodiment, a plurality of devices required to execute a series of workflows from “prepress” to “post processing (postpress)” are provided. The production management computer (for example, server computer PC103) to be connected can be connected via the network 101, and each device can be managed by the computer 103.

  As described above, the POD system 10000 according to the present embodiment enables data communication between the printing apparatus 100 and the computer 104 via the network 101. Data communication via the network 101 is also possible between the printing apparatus 100 and a non-offline finisher (such as the sheet processing apparatus 200 and the nearline finisher 108 or 109). Furthermore, data communication via the network 101 is also possible between the computer 104 and a non-offline finisher (such as the sheet processing apparatus 200 and the nearline finisher 108 or 109). In data communication with a plurality of devices that execute different processes necessary for creating a printed material, highly versatile digital data (XML) can be used. As a specific configuration necessary for this, as described above, in the present embodiment, the control unit 205 controls the printing apparatus 100 to process a JDF job as a print job using XML data.

According to the configuration of the present embodiment, for example, since the printing system does not support JDF, it is possible to cope with needs that are not dealt with or difficult to deal with. These needs include the following:
(1) Needs to improve productivity at the level of individual machines and work, so we want to manage from upstream to downstream and improve productivity.
(2) Needs such as “I want to prevent waste and mistakes in the transmission of production information”.
(3) “In spite of the fact that the data to be printed is electronic data created on the customer's PC, the sales person enters the order slip in handwriting on paper, and production management makes a production plan based on this. , "CTP and printing work flow" problem. In other words, there is a need to improve the efficiency of "unmatched work flow in which paper and electronics are mixed, such as when some work is done on paper and another work is done using a computer."

In order to cope with the needs that may be required in such a POD environment, a JDF job is received by the printing apparatus 100 and can be executed by the printing system 1000. In this way, the printing system 1000 that can support the JDF format can cope with various needs. In particular, for example, this embodiment is focusing on assumptions as an example of the advantages of JDF. “All of the order slips, work instructions, completion reports, daily reports, etc. used inside the printing company can be digitized. The printing system 1000 can realize advantages unique to JDF. In addition, for example, it is possible to realize the advantages of JDF jobs such as “salespersons can grasp in detail what jobs are currently being produced by CTP, printing machines, and bookbinding machines”. . In addition, since the JDF job uses XML, it is possible to obtain the advantage of being able to confirm and give instructions using an in-house portal, browser, or PDF, which can contribute to the improvement of work efficiency. Paying attention to the above points,
In this embodiment, a “JDF job” corresponding to the first type job can be accepted as a job to be printed by the printing apparatus 100. Based on this configuration, in the present embodiment, a job of a type different from the “JDF job” corresponding to the first type of job can be accepted as a job to be printed by the printing apparatus 100. For example, since both the functions of the printing apparatus 100 and the function of the sheet processing apparatus 200 can be utilized to the maximum, printing can be performed via a printer driver unique to the printing system 1000 that does not depend on other devices. An execution request can be accepted. For example, a printer driver dedicated to the printing apparatus 100 manufactured by the manufacturer of the printing apparatus 100 is installed in the PC 103 or the PC 104 (external device). Further, in response to an operation using the mouse or keyboard of the external device, the CPU of the external device activates the printer driver for the printing apparatus 100 and displays the printer driver setting screen on the display unit. In addition, a print operation condition and a print execution request of a job to be processed are received by a user operation via a printer driver setting screen displayed on the display unit of the external device. As a result, the CPU of the external apparatus transmits the job data to the printing apparatus 100 via the network 101. At this time, the CPU of the external device converts the job data to be executed by the printing apparatus 100 into, for example, data that is not in the JDF format, for example, unique non-JDF data of the printing apparatus 100 (for example, in the PDL format). Data). As described above, the printing system 1000 according to the present embodiment can accept not only JDF jobs corresponding to the first type job but also non-JDF compatible data that is not JDF format data as processing target jobs.

  In this embodiment, this “non-JDF format data” job is defined as a “non-JDF job” and is also referred to as a second type job. In this embodiment, this “non-JDF job” is defined as “a job that is permitted to be accepted by the printing system 1000 in which various execution requests to the printing system 1000 are described in a language other than the XML language”. ing. For example, a “PDL format job” that is an example of this “non-JDF job” can also be received via the external I / F unit 202 of the printing system 1000. In this case, the control unit 205 causes the printing system 1000 to execute processing required for the PDL format job received by the printing system 1000. In other words, the control unit 205 receives, from the printing apparatus 100, a “job in which a series of processing condition data including printing conditions and post-processing conditions during printing by the printer unit 203 is expressed in a data format other than JDF format data”. The printing system 1000 is controlled as possible.

  The non-JDF job also includes a job to be processed in which a print execution request by the printing apparatus 100 of the printing system 1000 is made by the operator via the UI unit of the present embodiment. In this way, when the printing system 1000 receives a non-JDF job that requires print processing, for example, via the external I / F unit 202 or the like, the control unit 205 distinguishes the above-described JDF job processing from the non-JDF job. Is processed by the printing system 1000. For this purpose, a computer-readable control program is read from the HDD 209 and executed. Then, processing based on this non-JDF job can be executed by control according to the program.

  For example, assume that the job to be processed for which printing is requested is a JDF job. In this case, when the data of the JDF job is stored in the HDD 209, the control unit 205 specifies what print processing conditions are set in the XML data of the JDF job. The control unit 205 also reads out the system configuration information of the printing system 1000 from the HDD 209 and confirms it. As a result, the control unit 205 determines whether or not the printing system 1000 can execute all processing necessary for the print request in the JFD job.

  For example, the accepted JDF job is “a job that can be executed by the printing system 1000, although some of the processes specified by the JDF job cannot be executed by the printing system 1000”. Alternatively, the JDF job is “a job that cannot be executed by the printing system 1000 in any of a plurality of processes specified by the JDF job”. Assume that the control unit 205 makes a determination corresponding to at least one of these cases. Here, a JDF job corresponding to one of these cases is defined as an “incompletely consistent JDF job”.

  As described above, on the condition that the job to be processed is an “incompletely-matched JDF job”, the control unit 205 preliminarily holds the “control rule for processing the JDF job” stored in the HDD 209 of the printing apparatus 100. The control rule information is managed in the aforementioned management table (rule information storage unit). As a result, “a job corresponding to an incompletely consistent JDF job is prohibited from starting printing. Further, it is assumed that a setting such as “execute job cancel processing for ending the job processing” is set in advance in the printing system 1000. In this case, the control unit 205 prohibits the printer unit 203 from printing the print data of the “incomplete match type JDF job” received via the external I / F 202. In addition, the control unit 205 automatically ends the processing of the job even if no processing stop request is input by the operator. In addition, the control unit 205 performs control so that the job data including the print data held in the HDD 209 is deleted from the HDD 209. Such cancellation processing of “non-perfect match type JDF job” is controlled to be automatically executable according to the rule information for the JDF job set in advance in the printing system 1000.

  On the other hand, as a result of confirming the control rule information for the JDF job, even if it is an incompletely consistent JDF job, items that can be processed by the printing system 1000 are executed by the printing system 1000 and cannot be executed by the printing system 1000. It is assumed that the processing is ignored (does not print), so that printing is not prohibited and execution of the printing process by the printer unit 203 is permitted. In this case, the control unit 205 does not prohibit printing of the “non-perfect match type JDF job” received via the external I / F 202 by the printer unit 203, but reads and prints the print data from the HDD 209. Let In addition, the control unit 205 does not execute a process that cannot be executed by the printing system 1000 among a plurality of processes specified by the JDF job, or changes to a default setting process that can be executed by the printing system 1000. The printing system 1000 is controlled to execute. In addition, the control unit 205 executes processing that can be executed by the printing system 1000 among the plurality of processing specified by the JDF job according to the command. Such a printing process that prohibits the cancellation process of the “non-perfect match type JDF job” can be automatically executed according to the rule information of the JDF job set in advance in the printing system 1000. In this embodiment, the processing that can be executed by the printing system 1000 without canceling the processing of the “incompletely consistent JDF job” is executed as described in “Degenerate processing of incompletely consistent JDF job”. ".

  Further, when the accepted JDF job is “a job that can be executed by the printing system 1000 for all of a plurality of processes instructed by the JDF job”, the job is designated as a “JDF job whose processing condition is a complete match type”. Is defined. In this case, the control unit 205 prints the print data of the “perfect match type JDF job” received via the external I / F 202 without referring to the rule information. In addition, the control unit 205 causes the printing system 1000 to execute all the processes requested by the job.

  Based on the above configuration, for example, when a non-JDF job is received via the external I / F 202 while the printer unit 203 is executing a JDF job print process, the control unit 205 sets the non-JDF job to a print waiting state. Is stored in the HDD 209 as a job. Then, until the processing of the preceding JDF job is completed, the printing start of this non-JDF job is waited. When it is confirmed that the printing process for the preceding JDF job has been completed, the control unit 205 causes the printer unit 203 to start the printing process for the subsequent non-JDF job. Here, when accepting a non-JDF job, the control unit 205 refers to the control rule information for the non-JDF job that is managed in advance in the HDD 209 separately from the control rule information for the previous JDF job. Then, the processing of the non-JDF job is controlled according to the control rule information for the non-JDF job. In this way, control and processing distinct from JDF job processing are executed for non-JDF jobs.

  For example, a non-JDF job accepted by the printing system 1000 is “a part of a plurality of processes designated by the non-JDF job cannot be executed by the printing system 1000, but the rest of the processes are performed by the printing system 1000. This is an executable job. Alternatively, the non-JDF job is “a job in which none of the processes specified by the non-JDF job can be executed by the printing system 1000”. It is assumed that the control unit 205 determines that it corresponds to at least one of these cases. Here, a non-JDF job corresponding to at least one of the cases is defined as a “non-perfect match type non-JDF job”. In this way, when the job to be processed is a “non-perfect match type non-JDF job”, the control unit 205 holds “control rule information for processing a non-JDF job” stored in the HDD 209 of the printing apparatus 100. Is read and referenced. And according to the result, the control part 205 can perform control as shown below. For example, as a result of referring to the control rule information, a setting of “execute job cancel processing for prohibiting printing of a job corresponding to an inexact match type non-JDF job and ending processing of the job” is instructed. To do. In this case, the control unit 205 prohibits the printer unit 203 from printing the print data of the “non-perfect match type non-JDF job”. In addition, the control unit 205 automatically ends the processing of the non-JDF job without inputting a processing stop request by the operator. In addition, the control unit 205 deletes the data of the non-JDF job including the print data held in the HDD 209 from the HDD 209.

  In this way, the control unit 205 automatically executes the cancellation process of the “non-perfect match type non-JDF job” according to the non-JDF job rule information for the non-JDF job preset in the printing system 1000. Control as possible.

  On the other hand, as a result of referring to “control rule information for processing a non-JDF job”, processing that can be processed by the printing system 1000 is executed, and processing that cannot be executed is set to be ignored (not performed). To do. In this case, it is assumed that the printing system 1000 is instructed in advance to set “permit execution of print processing by the printer unit 203 without prohibiting printing”. In this case, the control unit 205 reads the print data from the HDD 209 and prints it without prohibiting the printer unit 203 from printing the print data of the “non-perfect match type non-JDF job”. In addition, the control unit 205 does not execute a process that cannot be executed by the printing system 1000 among a plurality of processes specified by the non-JDF job, or changes to a default setting process that can be executed by the printing system 1000. Then, control is performed to execute the process after the change. In addition, the control unit 205 causes a process according to the instruction to be executed for a process that can be executed by the printing system 1000 among a plurality of processes specified by the non-JDF job.

  Control is performed so that the print processing in which the cancel processing of the “non-perfect match type non-JDF job” is prohibited is automatically executed according to the rule information for the non-JDF job preset in the printing system 1000. In the present embodiment, the processing that can be executed by the printing system 1000 without canceling the processing of the “non-perfect match type non-JDF job” as described above is performed as “non-perfect printing”. This is referred to as “matching-type non-JDF job degeneration processing”.

  Furthermore, the non-JDF job is a “job that can be executed by the printing system 1000 in all of a plurality of processes specified by the non-JDF job”. The non-JDF job determined by the control unit 205 in this way is defined here as a “non-JDF job whose processing conditions are exactly the same”. In this case, the control unit 205 reads the print data from the HDD 209 without referring to the rule information for the non-JDF job, and does not prohibit the printing of the accepted “perfect match non-JDF job”. Print. In addition, the control unit 205 causes the printing system 1000 to execute all processing required for the job. In addition, in the present embodiment, the control for the non-JDF job can be executed by the printing system 1000 separately from the above-described control for the JDF job. For example, as a first control example, the control unit 205 automatically cancels the non-perfect match type non-JDF job according to the rule information for the non-JDF job for the non-JDF job preset in the printing system 1000. To make it executable. In addition, the control unit 205 executes this non-JDF job cancel control “automatically execute the non-perfect match type JDF job cancel process according to the rule information for the JDF job preset in the printing system 1000. Is set as follows.

  In such a situation, the control unit 205 allows the printing system 1000 to accept a JDF job even during a period during which control is performed so as to execute a “non-perfect match non-JDF job” cancel process. If a JDF job is received during this period, the control unit 205 causes the printing system 1000 to execute processing according to the rule information for the JDF job. For example, on the condition that this JDF job is an “incompletely consistent JDF job”, the control unit 205 causes the printing system 1000 to execute a cancellation process for the JDF job.

  Further, as a second control example different from the first control example, for example, “a non-JDF job for a non-JDF job preset in the printing system 1000 for canceling a non-perfect match type non-JDF job” may be used. Can be automatically executed according to the rule information for Further, the control unit 205 automatically executes the non-JDF job cancellation control according to the rule information for the JDF job set in advance in the printing system 1000. Execute even if it is set to Execute.

  In this way, the J1000 job can be accepted by the system 1000 even during the period when the printing system 1000 is controlled to execute the cancel process of “non-perfect match type non-JDF job”. If this JDF job is accepted during this period, the control unit 205 causes the printing system 1000 to execute processing according to the rule information for the JDF job. For example, when the JDF job is an “incompletely consistent JDF job”, the control unit 205 causes the printing system 1000 to execute the JDF job degeneration processing.

  Further, as a third control example different from the second control example, for example, “a non-JDF job for a non-JDF job preset in the printing system 1000 for a non-perfect match non-JDF job degeneration process” may be used. Can be automatically executed according to the rule information for In the present embodiment, the control unit 205 performs the non-JDF job reduction control according to the rule information for the JDF job set in advance in the printing system 1000 as “non-perfect match type JDF job reduction processing”. Execute even if it is set to “Execute automatically”.

  In this way, the control unit 205 also allows the printing system 1000 to accept a JDF job even during a period in which the printing system 1000 is controlled to execute the “non-perfect match type non-JDF job” reduction process. In addition, when a JDF job is accepted during this period, the control unit 205 causes the printing system 1000 to execute processing according to the rule information for the JDF job. For example, when the JDF job is an “incompletely consistent JDF job”, the control unit 205 causes the printing system 1000 to execute the JDF job degeneration processing.

  Further, as a fourth control example different from the third control example, for example, “a non-JDF job for a non-JDF job preset in the printing system 1000 for a non-perfect match non-JDF job degeneration process” may be used. Can be automatically executed according to the rule information for Further, the control unit 205 can automatically execute the non-JDF job reduction control according to the rule information for the JDF job set in advance in the printing system 1000. In the case of “No.

  In this way, the control unit 205 also allows the printing system 1000 to accept a JDF job even during a period in which the printing system 1000 is controlled to execute the “non-perfect match type non-JDF job” reduction process. In addition, when a JDF job is accepted during this period, the control unit 205 causes the printing system 1000 to execute processing according to the rule information for the JDF job. For example, if the JDF job is an “incompletely consistent JDF job”, the control unit 205 causes the printing system 1000 to execute a cancellation process for the JDF job.

As described above, in this embodiment, the printing system 1000 can accept a plurality of types of jobs including a first type job corresponding to a JDF job and a second type job corresponding to a non-JDF job.
On the premise of such a configuration, the control unit 205 confirms whether or not the JDF job is an incompletely-matched JDF job on the condition that the accepted job to be processed is a JDF job. . As a result, the control unit 205 controls the system 1000 to execute the processing for the JDF job as described above on the condition that the JDF job is confirmed to be an incompletely-matched JDF job. When it is confirmed that the accepted job to be processed is a non-JDF job, the control unit 205 confirms whether the non-JDF job is a non-perfect match type non-JDF job. As a result, when it is confirmed that the non-JDF job is a non-perfect match type non-JDF job, the control unit 205 controls the printing system 1000 to execute processing for the non-JDF job. In this way, the printing system 1000 can independently execute control for JDF jobs and control for non-JDF jobs.

  Also, assuming such a configuration, the control unit 205 can accept a processing request for a non-JDF job while the printing system 1000 is executing a printing process required for a JDF job. In addition, the non-JDF job accepted during execution of printing of this JDF job is stored in the HDD 209 as a job waiting for printing, and the execution thereof is put on standby. When the printing process for the JDF job is completed in the system 1000, the printing process for the waiting non-JDF job can be executed. In addition, while the printing system 1000 is executing a printing process that requires a non-JDF job, the control unit 205 can accept a JDF job processing request. The control unit 205 stores the JDF job received during printing of the non-JDF job in the HDD 209 as a job waiting for printing, and waits for the start of the processing. When the printing of the non-JDF job is completed, the control unit 205 enables the system 1000 to execute the printing process of the waiting JDF job.

  The above-described configuration is also one of the characteristic points of the printing system 1000 according to the present embodiment.

  As described above, the printing system 1000 according to the present embodiment includes at least the JDF-compatible printing apparatus 100 and makes it possible to use a common digital format (instruction sheet or job ticket) related to the entire printing process.

  As its merit, in the present embodiment, as described above, for example, attention is paid to the following points.

  For example, JDF uses XML, which is the basic format of the Web, for its format. We are paying attention to the fact that JDF can provide management advantages related to the entire printing process, such as confirming the operation status of each device such as production management, printing machine, bookbinding machine, etc. on this website using this characteristic. . In the present embodiment, this advantage can be enjoyed even if the printing system 1000 is used.

In addition, it is possible to describe an instruction relating to a series of work processes in which a plurality of devices cooperate with each other in addition to a single device such as a submission process to a delivery process related to a printed matter as a final product, using an instruction sheet in JDF format. Using this specification, it is also possible to manage a series of workflows composed of a plurality of processes using a plurality of devices with a single instruction by using JDF. JDF has advantages in terms of cooperation between a plurality of devices and automation of various devices related to the overall printing process. Furthermore, in this embodiment, in addition to these, in particular, it is possible to cope with the following problems that still have room for examination.
・ Problem 1
If a printing device or printing system having a configuration corresponding to a JDF job simply cannot produce a printed material as instructed by JDF, the printing device or printing system executes the printing process for that JDF job. It is difficult to deal with user needs that do not want to.

  For example, unlike a printer driver prepared specifically for a printing apparatus, a JDF setting can be created without knowing the specifications and configuration information of the printing apparatus. This is a common format that does not depend on a single device, and can be said to be a configuration that takes advantage of JDF-specific advantages for the purpose of processing jobs with various devices as much as possible. However, for example, depending on the execution environment (capability and equipment status of the printing device or system, etc.), there is a possibility that the operation instructed by the JDF job may not be completely executed by the printing device or printing system. means.

  From the viewpoint of the user, for example, when printing is instructed using JDF, if the printed matter cannot be created by the printing apparatus (printing system), the processing of the job is canceled. Is expected as the user needs. In particular, in the POD printing environment according to the present embodiment, it is assumed that the printing system 1000 creates a printed material as a product to be delivered to a customer. In such a printing environment, creating a printed matter as a product with the printing system 1000 does not make any sense to create a printed matter that the customer does not want, and the failure cost may only increase wastefully. Is expected.

On the other hand, according to the present embodiment, such a problem 1 can be solved, and the above-described user needs specific to the POD environment assumed in the printing environment can be dealt with.
・ Problem 2
A printing apparatus or printing system that only supports JDF jobs is difficult to cope with user needs for processing with a JDF job even if a printed matter as instructed by JDF cannot be created.

  For example, it is assumed that finishing that cannot be executed by the sheet processing apparatus 200 of the printing system 1000 is specified in the JDF job. In this case, the printing system 1000 cannot execute the process. However, for example, a non-inline type finisher such as an offline finisher or an inline finisher is prepared at a work site where the printing system 1000 is set, such as the POD system 10000. In this case, it is expected that even if the processing cannot be performed by the inline finisher of the printing system 1000, a printed matter as a product can be created by using a non-inline type inline finisher. In such a case, for example, a printed material as instructed by the JDF cannot be completed by the printing system 1000 alone, but can be completed by using a non-inline type finisher. Therefore, even when the printing system 1000 cannot complete a printed product as a product, it is desired that the printing system 1000 execute processing that can be performed by the printing system 1000, such as printing processing for a JDF job. That is more efficient in processing large print jobs from more customers. It is conceivable that the user needs considering the overall productivity of such a plurality of jobs are required by the operator at the work site of the printing system 1000 in this POD environment.

  As described above, in this embodiment, even if a printed matter as instructed by JDF cannot be created by the printing apparatus or system, the user needs to process a JDF job as described above will be required in the POD printing environment in the future. Focuses on what can be required. However, it is difficult to cope with this need only with a printing apparatus or a printing system having a configuration corresponding to a JDF job.

  According to the present embodiment, such a problem 2 can be solved, and the above-described user needs peculiar to the printing environment assumed in the POD printing environment can be dealt with.

  As illustrated above, JDF format data can be expected from the viewpoint of versatility, device automation, device cooperation, device management, etc., but it is prepared only for one device or a specific type of device. It is not the data that is being used. Therefore, due to this, the above case may occur. As a result, the printing system 1000 is configured to be able to provide a printing system and a printing apparatus that can flexibly cope with various user needs as described above. One of the feature points. It should be noted that not all the configurations described above may be included. In other words, any configuration may be used as long as at least one of the effects related to the JDF described in the present embodiment can be obtained. However, it is desirable to include at least the following components.

  The printing system 1000 is configured such that a plurality of types of jobs can be processed by the printing apparatus 100 as jobs requiring printing processing. As the plurality of types of jobs, a JDF job in which a plurality of processing conditions are specified using at least an XML language, and a non-JDF job (for example, a PDL job) in which a plurality of processing conditions are specified in a language other than the XML language Can be accepted.

  On the assumption of this configuration, the control unit 205 executes the following control. For example, the job to be processed is “a JDF job, not a non-JDF job”. This is defined as condition A. Further, the JDF job is “a JDF job including processing conditions that cannot be executed by the printing system 1000”. This is defined as condition B. When these two conditions A and B are satisfied, the control unit 205 controls the system 1000 so that the print processing of the JDF job can be canceled.

  On the premise of the above configuration, the control unit 205 also executes the following control. For example, the job to be processed is “JDF job, not non-JDF job” (condition A). In addition, the JDF job is “a JDF job including processing conditions that cannot be executed by the printing system 1000” (condition B). In other words, when the condition A and the condition B are satisfied, the control unit 205 does not cancel the printing process of the JDF job, but can be executed by the printing system 1000 from among a plurality of processes required by the JDF job. Are controlled by the printing system 1000.

  On the premise of the above configuration, the control unit 205 also executes the following control. For example, the job to be processed is “JDF job, not non-JDF job” (condition A). In addition, the JDF job is “a JDF job including processing conditions that cannot be executed by the printing system 1000” (condition B). That is, when the condition A and the condition B are satisfied, the control unit 205 controls the printing process of the JDF job as follows. In other words, among the plurality of processes required for the JDF job, the first process for executing the process executable by the printing system 1000 and the second process for canceling by the printing system 1000 can be selectively executed. .

  On the premise of the above configuration, the control unit 205 also executes the following control. For example, the job to be processed is “JDF job, not non-JDF job” (condition A). However, the JDF job is “a JDF job that does not include processing conditions that cannot be executed by the printing system 1000”. This is defined as condition C. When the two conditions A and C are satisfied, the control unit 205 causes the printing system 1000 to execute the printing process for the JDF job.

  On the premise of the above configuration, the control unit 205 also executes the following control. Based on the JDF job rule information relating to the JDF job stored in the HDD 209, the control unit 205 determines an action for the JDF job that includes processing conditions that cannot be executed by the printing system 1000. As a result, the process to be executed for the JDF job that satisfies the above two conditions A and B is determined.

  On the premise of the above configuration, the control unit 205 also executes the following control. While printing processing of JDF jobs is being executed by the printing apparatus 100, non-JDF jobs can be accepted. In addition, when the printing unit 100 receives a non-JDF job while the printing apparatus 100 is executing the printing process of the JDF job, the control unit 205 performs the printing process of the non-JDF job with the printing system 1000 after the printing process of the JDF job is completed. Make it executable. On the premise of the above configuration, the control unit 205 also executes the following control. The control unit 205 executes control for the non-JDF job independent of the control for the above-described JDF job.

  On the premise of this configuration, the control unit 205 also executes control exemplified below. The control unit 205 determines an action for a non-JDF job that includes processing conditions that cannot be executed by the printing system 1000 according to the rule information for the non-JDF job related to the non-JDF job stored in the HDD 209. As a result, the control unit 205 can execute either the non-perfect match type non-JDF job cancellation process or the non-perfect match type non-JDF job degeneration process according to the rules for the non-JDF job.

  On the premise of the above configuration, the control unit 205 also executes control exemplified below. The control unit 205 stores in advance in the HDD 209 rule information for a JDF job that determines an action for a JDF job that includes processing conditions that cannot be executed by the printing system 1000. In addition, the control unit 205 also stores in the HDD 209 rule information that determines a measure for a non-JDF job that includes processing conditions that cannot be executed by the printing system 1000 in a state that is distinguishable from the rule information. The contents of the rule information may be registered as device settings of the printing system 1000 by the operator via the user interface (for example, the operation unit 204) according to the present embodiment. Also, the HDD 209 is controlled so that print data of JDF jobs and print data of non-JDF jobs can be stored. In addition, when printing is performed by the printing apparatus 100, the print data of the JDF job and the non-JDF job is read from the HDD 209 and controlled to be printable by the printer unit 203. Such a configuration means that at least the following exemplary configurations are provided. For example, the control unit 205 can determine an action for a JDF job including processing conditions that the printing system 1000 cannot execute via the user interface according to the present embodiment. Further, the control unit 205 cancels or reduces the print processing of the JDF job that includes processing conditions that cannot be executed by the printing system 1000 based on the user setting for determining the action for the accepted JDF job. To decide. A configuration including at least one of the various components as described above is included in the present embodiment.

  With the configuration as described above, according to the present embodiment, at least one of the advantages related to the JDF job is achieved, and the problem related to the JDF job that has been difficult to deal with can be solved. In particular, in a POD printing environment that can be assumed when the printing apparatus or printing system is compatible with JDF, it is possible to contribute to the practical use of products that can cope with user needs that may be required in the future.

[Embodiment 3]
On the premise of the configuration described above, the effect of the present embodiment can be further improved by using the printing system 1000 so as to further include the configuration exemplified below. For example, in the above configuration, in the case of a reduction process as a JDF job setting with a common specification setting, a job that the control unit 205 determines to be an incompletely consistent JDF job when a job execution request is received is reduced. It was output. In the printing system 1000 according to the present embodiment, a job to be printed is registered in the print queue of the HDD 209 when a job execution request is received. Thereafter, the control unit 205 sequentially executes the jobs registered in the print queue, and outputs the jobs in a reduced manner. However, after the job is registered in the print queue, the job may be changed from an incompletely matched JDF job to a completely matched JDF job by changing the device configuration or status of the apparatus. In such a case, a process for changing an incompletely matched JDF job registered in the print queue to a completely matched JDF job in accordance with an instruction from the operator will be described. Note that the printing system 1000 causes a print job to be registered in the print queue of the HDD 209 to be printed even if the control unit 205 determines that the job is a completely matched JDF job when a print request is received. Based on such a configuration, the control unit 205 sequentially registers jobs to be handled as jobs to be printed in the print queue of the HDD 209.

  FIG. 30 is a flowchart for explaining processing by the control unit 205 when a job is received by the printing system according to the present embodiment (step S6 in FIG. 28). A program for executing this processing is stored in the ROM 207 and is executed under the control of the control unit 205.

  First, in step S91, the job information of the job accepted by the control unit 205 is analyzed, and it is determined whether or not the accepted job is a perfect match JDF job. If the accepted job is a perfect match type JDF job, or if it is a job other than a JDF job, the process proceeds to step S96, where the accepted job is saved in the HDD 209 and registered in the print queue.

  On the other hand, if it is determined in step S91 that the received job is a non-perfect match JDF job that is not a perfect match JDF job, the process advances to step S92 to determine whether or not the reduction setting is enabled in the common specification setting. If the reduction setting has been made, the process proceeds to step S96, where the accepted job is saved in the HDD 209 and registered in the print queue.

  FIG. 35 is a diagram illustrating a display example of a job status screen during execution of copy processing.

  FIG. 36 is a diagram showing a display example of a job status screen when an incompletely consistent JDF job is input during printing shown in FIG. 35 and is registered as waiting for printing in the HDD 209 as a degeneration target.

  On the other hand, if the reduction setting is not valid in the common specification setting in step S92, the process proceeds to step S93, and the job information and current device configuration information of the job are displayed from the UI unit. Then, it is determined whether or not it is possible to accept the change in the setting of the accepted incomplete match type job.

  FIG. 33 is a diagram showing a display example in step S93.

  When an incompletely matched job is input in this way, the operator can select whether or not to accept the job setting change by allowing the operator to select whether or not to perform the reduction process on the screen of FIG. Yes. In FIG. 33, for example, when the operator instructs the reduction execution button 9602, an alternative operation process or a skip operation process stored in advance in the HDD 209 is performed, and a job setting change process is performed (step S94). Based on the changed job information, the job is registered in the HDD 209 as a print waiting job. In FIG. 33, if the operator designates the non-degenerate button 9601, it is determined that the incompletely consistent job cannot be executed, and the data is canceled (step S93).

  FIG. 31 is a flowchart for describing print processing by the control unit 205 based on a job stored in the HDD 209 and registered in the print queue. A program for executing this processing is stored in the ROM 207 and is executed under the control of the control unit 205.

  First, in step S101, the control unit 205 determines whether there is a print waiting job registered in the HDD 209, and repeats this processing until a print waiting job is registered. If it is determined in step S101 that a print-waiting job is registered in the HDD 209, the process advances to step S102 to confirm processing of the print-waiting job.

  Next, the process proceeds to step S103, where it is determined whether or not the job is a complete match type job by comparing with the rule information. If the job is a complete match type job, the process proceeds to step S111, and the printer unit 203 performs print processing. I do.

  On the other hand, if it is determined in step S103 that the job is not an exact match job, the process advances to step S104 to determine whether the reduction setting is enabled. If the reduction setting is enabled, the process proceeds to step S111. In S111, the processing related to the function that is determined to be unable to complete the printing process in the job information of the incomplete match type JDF job is subjected to an alternative process set in advance in the HDD 209 or a skip process, and is sent to the printer unit 203. A print request is made by the print job.

  On the other hand, if it is determined in step S104 that the reduction setting is not enabled, the process proceeds to step S105, and whether a job other than the incompletely matched JDF job stored in the HDD 209 is registered as a print waiting job. Determine whether. If it is determined that a job other than an incompletely consistent JDF job is registered as a print waiting job, the process proceeds to step S106. In step S106, it is determined whether to postpone the print processing order of the incompletely consistent JDF job and give priority to the other print waiting jobs determined in step S105. The determination criterion of the order change in step S106 is performed by causing the UI unit to display a display for prompting determination as to whether or not to postpone the print processing order of the incompletely consistent JDF job. Further, the setting as to whether or not to postpone this printing order may be set in advance in the common specification setting. If it is determined in step S106 that the print processing order of the incompletely consistent JDF job is to be changed, the process proceeds to step S107, the print order of the job is changed, and the process returns to step S101 again.

  On the other hand, if no other print waiting jobs are registered in the HDD 209 in step S105, or if it is determined in step S106 that the printing order of the incompletely consistent JDF job is not changed, the process proceeds to step S108. In step S108, the job information of the corresponding job is displayed by the UI unit, and it is determined whether or not to accept the setting change of the incomplete match type job. If the job setting change is not accepted, or if the operator does not change the job setting even if the job information of the job is displayed by the UI unit, the process proceeds to step S110, and the incomplete match type job is executed. The job is judged to be impossible and the job is cancelled.

  On the other hand, if it is determined in step S108 that the setting change is accepted from the UI unit, the process proceeds to step S109, and all the processes related to the functions that are determined to be unprocessable in the incompletely matching job by comparison with the rule information. Change processing information. After the incompletely consistent job is changed to the completely consistent type in this way, the process proceeds to step S111, and a print request for the job is issued to the print unit 203.

  FIG. 32 is a flowchart for explaining processing when an event occurs that affects the device configuration of the printing system 1000 according to the present embodiment. A program for executing this processing is stored in the ROM 207 and is executed under the control of the control unit 205.

  This process is started when some event occurs, and when an event occurs, the process proceeds to step S121. Here, the event is an event that affects the function for performing the process described in the job information in the printing process, and it is determined whether the affected job is registered in the HDD 209 as a job waiting for printing. . If it is determined that the job to be affected is not registered as a job waiting for printing, the process returns to step S121 to wait for an event again.

  On the other hand, if it is determined in step S121 that the affected job is registered as a print-waiting job, the process proceeds to step S122, and whether the print job registered as the affected print-waiting job is a perfect match job or not. Determine whether. If it is determined in step S122 that the affected job is a perfect match job, the process proceeds to step S123, and the same processing as that at the time of job reception shown in FIG. 30 is performed for all the perfect match jobs. . After this processing is performed, the process returns to the beginning of the flow again and enters an event generation waiting state.

  FIG. 33 is a diagram illustrating a display example of a setting change acceptance UI.

  In the example of FIG. 33, the cutting machine cannot be used because the cutting waste is full, and the display example prompts whether or not to perform the reduction process for the job to be cut. If the user determines that the reduction process is to be performed, a reduction execution button 9602 is instructed. When the reduction execution button 9602 is instructed, the job information of the job that has become an incomplete match type is changed, and the printing process is continued. On the other hand, when the user determines not to execute the reduction process, a non-degeneration button 9601 is instructed.

  FIG. 34 is a diagram showing a display example of a UI when this degeneration process is not executed.

  Here, a cancel button 9603 can be instructed to cancel processing for this job, or an order change button 9604 can be instructed to select the job order to be postponed.

  Referring back to FIG. 32 again, if it is determined in step S122 that the affected job registered for printing is an incompletely consistent JDF job, the process proceeds to step S124. In step S124, it is determined whether or not the job can be changed to a perfect match type. If it is determined that the change is not possible, the process proceeds to waiting for an event. If it is determined that the job can be changed, the process proceeds to step S125, and the job is changed to a perfect match type.

  With reference to FIG. 37, FIG. 38 and FIG. 39, a case where a job change is accepted and changed from the incomplete match type to the complete match type will be described.

  FIG. 37 is a diagram illustrating an example of a job status display screen before an event that affects an incompletely consistent job occurs.

  In this state, an event that affects a non-perfect match type job occurs, and if it is determined in step S124 that the job can be changed to a perfect match type, the process proceeds to step S125, and the status of the job is changed. Process. For example, when the cutting waste is removed from the state where the cutting waste is full and the cutting becomes possible, the control unit 205 determines that the job set to cut can be changed to a completely consistent type. At that time, the control unit 205 displays the display screen shown in FIG.

  Here, when there is an incompletely-matched job whose processing execution order has been postponed with the above-described order change button 9604 (FIG. 34), it is possible to select whether or not to resume the job immediately. . If a button 9701 that is not immediately restarted is instructed here, control is performed so that the job is processed in the printing order when the order is set with the order change button 9604. On the other hand, when the button 9702 to resume immediately is instructed, the current printing job is temporarily interrupted, and control is performed to start printing an incompletely consistent job whose order has been postponed by the order change button 9604. To do.

  Further, in step S125, the status change process can be performed for all jobs corresponding to the postponed incomplete match type job.

  FIG. 39 is a diagram illustrating an example of a screen for performing a return setting for a temporary standby job.

  Here, it is possible to set whether to temporarily resume a job that is temporarily waiting (9702) or not immediately resume (9701).

  FIG. 39 is a diagram illustrating an example of a certain job status screen.

  For example, in the case of FIG. 39, in step S125, all the related reduction target jobs are changed to the completely matching type, and are registered as print waiting states.

  In the above example, the case where an event that affects an incompletely consistent job occurs when the job to be reduced is postponed has been described. However, the present invention can also be applied to the case where an event that affects an incompletely consistent job occurs when an alternative process or skip process preset in the HDD 209 is performed without deferring the job to be degenerated.

FIG. 40 is a diagram illustrating a display example of the degraded job return setting screen. Here, a display screen displayed on the operation unit 204 by the control unit 205 when the cutting waste is removed and cutting by the cutting machine can be executed is shown. This is the case when a job that has become a non-perfect match job can be changed to an exact match job by removing the cut waste because the cut waste is full and cannot be cut.
If the reduction continue button 9703 is instructed here, the current printing job is controlled to continue printing while being reduced. As a result, the finished printed matter of the job changes in the middle of the job, and the printed matter of the job is set in another post-processing device (cutting machine 109) to reduce the burden on the user when collectively processing. be able to. On the other hand, when the non-degenerate processing button 9704 button is instructed, control is performed such that the print setting of the non-perfect match type job is changed without degenerating the corresponding function.
