As shown in FIG. 5, the condition change information includes information on “target output job”, “alternative mode”, “target page”, and “change condition”. “Target output job” indicates a print job including a page that cannot be printed under the specified printing conditions. “Target page” indicates a page that actually changes the printing conditions in the target output job, that is, an alternative output. The page for which the condition is determined is shown. The “change condition” indicates what alternative output condition the print condition specified for the target page is to be changed to. The “alternative mode” indicates what criterion is used for changing the printing condition of the target page. In FIG. 5, in the situation where the A3 size paper (print medium) is paper end (medium shortage), and the A3 size is designated as the paper to be output for the third page of job A, the alternative output condition The condition change information produced | generated in the determination part 104 is illustrated. In the example of FIG. 5, since the “alternative mode” is “same as the previous page”, the paper size used for printing the third page of job A is the paper specified for the second page. It will be changed to size. If the paper size specified for the second page of job A is A4, the paper size used for printing the third page, which is the target page, is changed from A3 to A4. The “alternative mode” is set in the device in advance by, for example, initial setting. A specific example of this “alternative mode” will be described later in detail.

  The job control unit 105 performs job execution control that combines input and output under the management of the job management unit 102. In particular, the job control unit 105 is a print job in which a job to be executed is composed of a plurality of pages, and a part of the plurality of pages included in the print job includes a print condition designated for the page. When printing cannot be performed with the job management unit 102, the execution of the print job is controlled so that the page is printed with the alternative output condition determined by the alternative output condition determination unit 104 according to the command transmitted from the job management unit 102. .

  The data transfer unit 106 determines that when a part of a print job composed of a plurality of pages whose execution is controlled by the job control unit 105 cannot be printed under the print conditions specified for the page, This data is transferred together with a print instruction to another image forming apparatus on the network 400 determined as a print entrustment destination by the transfer determination unit 103. Here, the image forming apparatus determined by the transfer determination unit 103 as a printing entrustee is an image forming apparatus capable of printing under the printing conditions specified for the page to be entrusted to print. In the entrusted image forming apparatus, in response to a print instruction from the data transfer unit 106, the entrusted page is printed under the printing conditions specified for the page.

  The data receiving unit 107 receives the data and the print instruction from another image forming apparatus connected to the network 400 when the page data to be printed is transferred together with the print instruction via the network 400. Delivered to the job management unit 102. The job management unit 102 generates a new job for executing the printing of the entrusted page in response to the print instruction received by the data receiving unit 107.

  The document reading unit 108 provides an image input function for reading a document image by controlling a scanner device and generating image data that can be handled in the apparatus itself. The FAX receiving unit 109 provides an image input function for receiving FAX data input from a telephone line and generating image data that can be handled in the own apparatus. The document reading unit 110 provides an image input function for reading image data stored in a storage device inside the device.

  The FAX transmission unit 111 provides an image output function for transmitting image data from the own device to another device using a telephone line. The printing unit 112 provides an image output function for printing the image data in the own device on a sheet (print medium) by controlling the plotter device of the own device. Further, the document storage unit 113 provides an image output function for storing image data in a storage device inside the apparatus.

  The above units have been described as functional configurations included in the multifunction peripheral 100, which is one of the image forming apparatuses connected to the network 400. However, other units such as the printer apparatus 200 and the FAX apparatus 300 connected to the network 400 are described. Also in the image forming apparatus, the condition setting unit 101, the job management unit 102, the transfer determination unit 103, the alternative output condition determination unit 104, the job control unit 105, and the data transfer unit 106 are provided as a common functional configuration. . The printer apparatus 200 and the FAX apparatus 300 are different from the multi-function apparatus 100 only in the configuration of input means and output means. In the image forming system according to the present embodiment, each image forming apparatus may include at least the printing unit 112 as an output unit.

  In the image forming system according to the present embodiment, each of the image forming apparatuses of the MFP 100, the printer apparatus 200, and the FAX apparatus 300 connected to the network 400 has the above-described functional configuration, so that a print job including a plurality of pages. If some of the pages cannot be printed under the specified printing conditions, the printing of the pages is entrusted to another image forming apparatus, and the pages are replaced with other printing conditions that can be handled by the printer itself. To print. As a result, each image forming apparatus can cause the other image forming apparatus to print only pages that cannot be printed by the own machine, and can execute a print job without stopping the process on the own machine. It becomes possible.

  Note that the above-described functions of each image forming apparatus on the network 400 are realized by executing, for example, an image forming program provided in advance in a ROM or the like in each image forming apparatus. The image forming program executed by each image forming apparatus has a module configuration including a program for realizing each functional configuration described above. As actual hardware, a CPU (processor) stores an image forming program from the ROM. Is read and executed, a program for realizing each functional configuration is loaded onto the main storage device, and the above-described functional configurations are realized.

  The image forming program executed in each image forming apparatus on the network 400 is a file in an installable format or an executable format, and is a CD-ROM, flexible disk (FD), CD-R, DVD (Digital Versatile Disk). ) Or the like may be recorded and provided on a computer-readable recording medium. Further, the image forming program executed by each image forming apparatus may be stored on a computer connected to the network 400 and provided by being downloaded from the computer via the network 400 by each image forming apparatus. Further, the image forming program executed by each image forming apparatus may be provided or distributed via a network such as the Internet.

  Next, it is executed when the user performs an operation of copying a document composed of a plurality of pages in a multifunction peripheral 100 (hereinafter referred to as “device A”), which is one of the image forming apparatuses connected to the network 400. A series of processing will be specifically described with reference to the sequence diagrams of FIGS. 6-1 and 6-2. In the example shown in FIG. 6A and FIG. 6B, a five-page original (A3 size only for the third page) in which A4 size and A3 size originals are mixed, and A3 size paper is insufficient. This is an example in which copying is to be performed at A, and is an example in which printing conditions are designated to perform printing at the size of the document. On the network 400, there are devices B and C as image forming devices capable of printing in A3 size (image forming devices that hold A3 size paper), and device B is in a standby state. Yes, it is assumed that the device C is in a printing state. The process shown in FIG. 6B is executed following the process shown in FIG.

  When the activation of the device A is completed, as shown in FIG. 6A, the condition setting unit 101 first performs control to display an application selection screen as shown in FIG. 7 on the operation panel of the device A (step S1). . When the user presses the “Copy” button on the application selection screen, the condition setting unit 101 performs control to display a copy screen as shown in FIG. In response to a user operation input using this copy screen, a copy operation condition is generated (set) in the temporary storage memory (step S2). Here, although the operation condition generated on the temporary storage memory by the condition setting unit 101 varies depending on the selected application, in this example, since the copy application is selected, the operation condition to be generated is the reading condition and the printing condition. As the printing conditions, “Automatic Paper Selection” and “Same Size” are set by default, and unless the user changes the paper size or output magnification using the copy screen, It is set to print on the same size paper. In this example, the printing conditions are set so that printing is performed on a sheet of the same size as the original.

  Next, when the user sets a document to be copied on the scanner device of the device A and presses a start button provided on the operation panel, the condition setting unit 101 causes the operation condition (reading condition and printout) generated in the temporary storage memory. (Condition) is confirmed, and subsequent operation input from the operation panel is not accepted. As a result, it is possible to prevent the inconvenience that the setting contents are inadvertently changed during the execution of the job. Then, the condition setting unit 101 transfers the set operation condition information to the job management unit 102, and transmits a job execution control instruction to the job management unit 102 (step S3).

  When acquiring the operation condition information from the condition setting unit 101, the job management unit 102 generates a copy job including a reading job and a print job according to the operation condition set by the condition setting unit 101 (step S4). Then, the job control unit 105 is instructed to execute the generated copy job (step S5).

  The job control unit 105 controls the execution of the copy job generated by the job management unit 102 in response to an instruction from the job management unit 102. Specifically, the job control unit 105 first instructs the original reading unit 108 to specify the reading conditions and execute the original reading, and causes the original set on the scanner device of the device A to be read (see FIG. Step S6). The original reading unit 108 reads an original set on the scanner device in accordance with an instruction from the job control unit 105 (step S7), and transfers the image data of the read original to the job control unit 105 (step S8). ). In this example, since the five-page document is set in the scanner device of the device A, the image data of the first to fifth pages of the document is sent from the document reading unit 108 to the job control unit 105, respectively. .

  Next, the job control unit 105 sends image data to the printing unit 112 in order from the first page of the document, designates the printing conditions for each page, and instructs the execution of printing. The used printing is executed (steps S9-1 to S9-3). In response to an instruction from the job control unit 105, the printing unit 112 executes printing sequentially from the first page of the document under the designated printing conditions (steps S10-1 to S10-3), and whether or not printing has been performed normally. Is returned to the job control unit 105 (steps S11-1 to S11-3). In this example, a paper end occurs when the third page of the document is printed, and the third page of the document cannot be printed normally. Therefore, when the third page of the document is printed, the printing unit 112 sends the job control unit 105 to the job control unit 105. Status information indicating that normal printing has not been performed at the paper end is sent.

  When the job control unit 105 receives status information indicating that the third page of the document cannot be printed normally at the paper end from the printing unit 112, the job control unit 105 transmits the status information to the job management unit 102 and temporarily executes the print job. (Step S12).

  When the status information is transmitted from the job control unit 105, the job management unit 102 prints the third page of the original that has not been printed normally, that is, the A3 size paper that is insufficient in the device A. Information on the printing conditions for printing to the transfer determination unit 103 is transmitted (step S13).

  When the transfer determination unit 103 receives the print condition information for the third page of the document from the job management unit 102, the transfer determination unit 103 collects the above-described device capability information regarding each image forming apparatus on the network 400, and uses the collected device capability information. To generate the system operation information described above. Based on the generated system operation information, the transfer determination unit 103 holds an image forming apparatus corresponding to the printing condition of the third page of the document, that is, A3 size paper, and can print in A3 size. From among the various image forming apparatuses, an image forming apparatus to be commissioned to print the third page of the document is determined (step S14), and information for identifying the commissioned image forming apparatus is transmitted to the job management unit 102 (step S15). ). In this example, among the image forming apparatuses on the network 400, the device B and the device C hold A3 size paper, the device B is in a standby state, and the device C is in a printing state. The unit 103 generates the system operation information shown in FIG. Then, based on this system operation information, the transfer determination unit 103 selects a device B that is capable of printing in A3 size and that can be immediately printed out of the devices B and C capable of printing in A3 size. It is determined as an image forming apparatus that entrusts printing of the third page of the document. Information for identifying the device B that is a consignment destination is transmitted to the job management unit 102.

  When the job management unit 102 receives information for identifying the image forming apparatus (device B in this example) entrusting printing of the third page of the document from the transfer determination unit 103, the job management unit 102 sends the document 3 to the job control unit 105. It is instructed to entrust printing of the page to device B (step S16). The job control unit 105 sends the image data of the third page of the document to the data transfer unit 106 and transfers the image data of the third page of the document to the device B in response to the print commission instruction from the job management unit 102. To the data transfer unit 106 (step S17).

  In response to the instruction from the job control unit 105, the data transfer unit 106 transfers the image data of the third page of the document together with the print instruction to the device B on the network 400 (step S18). In the device B, the image data of the third page of the transferred document and the print instruction are received by the data receiving unit 107, and the job management unit 102 generates a print job according to the print instruction, and sends it to the job control unit 105. By instructing execution of the print job, the third page of the document is printed on A3 size paper.

  Next, as shown in FIG. 6B, the job management unit 102 determines an alternative output condition for printing the third page of the document on the own machine (device A) with respect to the alternative output condition determination unit 104. (Step S19).

  In response to an instruction from the job management unit 102, the alternative output condition determination unit 104 acquires information on the target print job and device capability information indicating the capability of the own device (device A), and based on the information. Thus, an alternative output condition for the third page of the document is determined according to the alternative mode set by the initial setting (step S20). Specifically, if the alternative mode is set to “same as previous page” and the paper used for printing the second page of the document is A4 size, the alternative output condition for the third page is printed to A4 size. To decide. Then, the alternative output condition determination unit 104 transmits the condition change information as shown in FIG. 5 indicating the determined alternative output condition to the job management unit 102 (step S21).

  Upon receiving the condition change information from the alternative output condition determination unit 104, the job management unit 102 changes the print condition for the third page of the document to the alternative output condition to the job control unit 105 (in this example, the output paper size A3 → A4) to instruct to resume the print job (step S22).

  In response to an instruction from the job management unit 102, the job control unit 105 changes the printing condition for the third page of the document to the alternative output condition (step S23), and resumes the temporarily interrupted print job execution. Let Then, the job control unit 105 instructs the printing unit 112 to print the third page of the document under the alternative output condition (step S24). In response to an instruction from the job control unit 105, the printing unit 112 prints the third page of the document under the alternative output condition (step S25), and displays status information indicating whether or not the printing has been performed normally. It returns to 105 (step S26).

  Thereafter, the job control unit 105 sends the image data of the remaining fourth and fifth pages of the document to the printing unit 112, and designates the printing conditions for each page to instruct the execution of printing (step) S27-1, S27-2). In response to an instruction from the job control unit 105, the printing unit 112 sequentially prints the fourth and fifth pages of the document under the designated printing conditions (steps S28-1 and S28-2), and normally Status information indicating whether printing is possible is returned to the job control unit 105 (steps S29-1 and S29-2).

  When the printing of the first to fifth pages of the document is completed, the job control unit 105 transmits status information indicating the end of the copy job to the job management unit 102 (step S30). Upon receiving the status information from the job control unit 105, the job management unit 102 notifies the condition setting unit 101 of the end of the copy job (step S31). The condition setting unit 101 receives the notification of the end of the copy job, and performs control to change the screen displayed on the operation panel of the device A from the copy screen to the application selection screen (step S32). Prepare for use.

  Next, a specific example of the “alternative mode” serving as a reference when the alternative output condition determining unit 104 determines the alternative output condition will be described.

(A) Same as previous page When “Alternative mode” is “Same as previous page”, the alternative output condition determination unit 104 is a page that cannot be printed with the capability of its own machine among a plurality of pages included in the print job. The alternative output condition is determined to be the same as the print condition specified for the previous page. For example, a part of a plurality of pages included in a print job is specified to be printed on paper of a size different from that of other pages, and the own machine holds the paper of the size specified for this part of the pages. If not, the paper size for printing the page is changed to the same size as the previous page. In this case, the previous page is normally printed, and the self-machine can cope with the print condition of the previous page, so that the alternative printing based on the alternative output condition is surely performed.

(B) Paper Size Different from the Previous Page When the “alternative mode” is “paper size different from the previous page”, the alternative output condition determination unit 104 determines that the page on which alternative printing is performed is a paper having a size different from that of the previous page. The alternative output condition for the page is determined so that the page is printed. For example, the printing condition of the previous page is a condition that printing is performed on A4 size paper using the first paper feed tray, and the B4 size paper is loaded on the second paper feed tray as the device configuration of the own machine. If it is set, the printing condition for the page to be subjected to the alternative printing is changed to a condition for printing on B4 size paper using the second paper feed tray.

  As in the image forming system according to the present embodiment, a certain image forming apparatus on the network 400 causes another image forming apparatus to print a page that cannot be printed under the printing conditions specified by itself, and the page is displayed. When alternative printing is performed on the own machine under the alternative output condition, the user intends to replace (merge) the page printed on the alternative machine with the one printed on the other image forming apparatus. A printed matter can be obtained. At this time, if the position of the substitute printed page is known at a glance, the merging operation by the user becomes simple. As in the above example, when a page to be subjected to alternative printing is printed on a paper having a size different from that of the previous page, the user can easily determine the position of the page that has been subjected to alternative printing, and the merge operation can be performed easily. .

(C) Paper type different from the previous page When the “alternative mode” is “paper type different from the previous page”, the alternative output condition determination unit 104 determines that the page on which alternative printing is performed is a paper type different from the previous page. The alternative output condition for the page is determined so that it is printed on a sheet of paper that is owned by the own machine. Also in this case, since the user can easily determine the position of the page that has been subjected to the alternative printing, the merging operation can be easily performed.

(D) Paper Color Different from the Previous Page When the “alternative mode” is “paper color different from the previous page”, the alternative output condition determining unit 104 determines that the page on which the alternative printing is performed is a different color from the previous page. Then, an alternative output condition for the page is determined so as to be printed on a sheet held by the own apparatus. Also in this case, since the user can easily determine the position of the page that has been subjected to the alternative printing, the merging operation can be easily performed.

(E) Tab Sheet When the “alternate mode” is “tab sheet”, the alternate output condition determination unit 104 displays the tab sheet so that the page to be subjected to the alternate printing is printed on the tab sheet that can be handled by the own machine. Determine alternative output conditions for the page. Also in this case, since the user can easily determine the position of the page that has been subjected to the alternative printing, the merging operation can be easily performed.

  FIG. 9 is a flowchart showing an outline of processing in which the alternative output condition determining unit 104 determines the alternative output condition according to the alternative mode. When the alternative output condition determination unit 104 determines an alternative output condition for a page to be subjected to alternative printing, for example, the alternative output condition determination unit 104 confirms the “alternative mode” set in the own apparatus by initial setting. When the five (A) to (E) described above exist as “alternative modes”, the alternative output condition determination unit 104 determines whether the “alternative mode” is “same as the previous page” (step S101). Whether the “alternative mode” is “paper size different from the previous page” (step S102), whether the “alternative mode” is “paper type different from the previous page” (step S103), “ It is sequentially determined whether or not “alternative mode” is “paper color different from the previous page” (step S104). When all the determination results are NO, the “alternative mode” is “tab paper”.

  Then, if the “alternative mode” is “same as previous page”, the alternative output condition determination unit 104 checks whether there is a remaining amount of paper that is the same as that of the previous page (step S105). If there is, the alternative output condition for the page is determined so that the page to be replaced is printed on the same sheet as the previous page (step S106). On the other hand, if the same sheet as the previous page is insufficient, the process ends without determining the alternative output condition.

  Further, if the “alternative mode” is “paper size different from the previous page”, the alternative output condition determination unit 104 checks whether or not the own machine has a paper having a size different from that of the previous page (step S107). If so, the alternative output condition for the page is determined so that the page to be replaced is printed on a sheet having a different size from the previous page (step S108). On the other hand, if the own machine does not have paper of a size different from that of the previous page, it is checked whether there is a remaining amount of paper that is the same as that of the previous page (step S105). The alternative output condition for the page is determined so that the page to be printed is printed on the same sheet as the previous page (step S106).

  Further, if the “alternative mode” is “a paper type different from the previous page”, the alternative output condition determination unit 104 checks whether or not the own machine possesses a paper type different from the previous page (step S100). In step S109, the alternative output condition for the page is determined so that the page to be subjected to the alternative printing is printed on a paper of a paper type different from that of the previous page (step S110). On the other hand, if the own machine does not have a paper type that is different from the previous page, it is checked whether there is a remaining amount of paper that is the same as that of the previous page (step S105). An alternative output condition for the page is determined so that the page to be printed is printed on the same sheet as the previous page (step S106).

  Also, if the “alternative mode” is “paper color different from the previous page”, the alternative output condition determination unit 104 checks whether or not the own machine has a paper of a color different from the previous page (step S111). If so, the alternative output condition for the page is determined so that the page to be replaced is printed on a sheet of a color different from that of the previous page (step S112). On the other hand, if the own machine does not have paper of a color different from that of the previous page, it is checked whether there is a remaining amount of paper that is the same as that of the previous page (step S105). The alternative output condition for the page is determined so that the page to be printed is printed on the same sheet as the previous page (step S106).

  Further, if the “alternative mode” is “tab paper”, the alternative output condition determination unit 104 checks whether or not the own device has tab paper (step S113). The alternative output condition of the page is determined so that the page to be printed is printed on the tab sheet (step S114). On the other hand, if the own device does not have a tab sheet, it is checked whether there is a remaining amount of paper that is the same as that of the previous page (step S105). The alternative output condition for the page is determined so as to be printed on the same sheet as (step S106).

  As described above in detail with specific examples, in the image forming system according to the present embodiment, each of the image forming apparatuses such as the multifunction peripheral 100, the printer apparatus 200, and the FAX apparatus 300 connected to the network 400. However, if some pages of a print job consisting of multiple pages cannot be printed under the specified printing conditions, the printing of the pages can be entrusted to another image forming apparatus and the pages can be handled by the printer itself. Instead of other printing conditions, printing is performed. As a result, each image forming apparatus can cause the other image forming apparatus to print only pages that cannot be printed by the own machine, and can execute a print job without stopping the process on the own machine. It becomes possible. In addition, by performing alternative printing of a page for which printing has been outsourced to another image forming apparatus, it is possible to reduce the time and effort of the merge work by the user.

Next, a modification of this embodiment will be described.
(Modification 1)
In the first modification, when a page that cannot be printed under specified printing conditions is printed under alternative output conditions (alternative printing), information indicating that the printing of the page is alternative printing is added and printed. is there. Specifically, for example, a character image such as “This page is alternative printing” is added to a sheet on which alternative printing is performed. In this case, as a functional configuration of an image forming apparatus (for example, the multifunction peripheral 100) that performs alternative printing, a guide image generation unit 114 for generating a character image as described above is added as shown in FIG. In this image forming apparatus (for example, the multifunction machine 100), when the printing unit 112 performs alternative printing under the control of the job control unit 105, the above-described character image is generated by the guide image generation unit 114. A character image is printed on paper by the printing unit 112. In this way, by performing printing by adding information indicating that the page is alternative printing at the time of alternative printing, the user can distinguish the alternative printed page at a glance and perform merge work. It becomes possible to carry out more simply.

(Modification 2)
In the second modification, when a page that cannot be printed under specified printing conditions is printed under alternative output conditions (alternative printing), the page that is the target of alternative printing is printed as a thumbnail image that is smaller than the size that should be output originally. Is. In this case, a thumbnail image generation unit 115 for generating a thumbnail image is added as a functional configuration of an image forming apparatus (for example, the multifunction peripheral 100) that performs alternative printing, as shown in FIG. In this image forming apparatus (for example, the MFP 100), when the printing unit 112 performs alternative printing under the control of the job control unit 105, the thumbnail image of the page to be subjected to alternative printing by the thumbnail image generation unit 115 is displayed. The thumbnail image is generated and printed on a sheet by the printing unit 112. In this way, by printing the thumbnail image of the target page at the time of alternative printing, the user can distinguish the alternative printed page at a glance and can perform the merge operation more easily. Become.

(Modification 3)
The third modification is an image forming apparatus that prints a page that cannot be printed under the designated printing condition under the alternative output condition (alternative printing), that is, the printing of the page. Information (device name or the like) for identifying the image forming apparatus to which the page data has been determined and transferred as a consignee is added and printed. In this case, as a functional configuration of an image forming apparatus (for example, the multifunction peripheral 100) that performs alternative printing, as shown in FIG. 12, a character for generating a device name of the image forming apparatus that is a print entrustee as a character string image. A column image generation unit 116 is added. In this image forming apparatus (for example, the multifunction peripheral 100), when the printing unit 112 performs alternative printing under the control of the job control unit 105, the character string image generation unit 116 uses the device name of the image forming apparatus that is a print consignment destination. Are generated as a character string image, and the character string image is printed on a sheet by the printing unit 112. As described above, by adding the information for identifying the image forming apparatus that is a print consignment destination in the alternative printing, the user can easily specify the image forming apparatus that is the print consignment destination.

(Modification 4)
In Modification 4, when pages that cannot be printed under specified printing conditions are continuously included in the print job, alternative printing is performed only on the first page of these consecutive pages, and the remaining pages are not processed. Alternative printing is not performed. The outline of the process of the modification 4 is shown in the flowchart of FIG. In the fourth modification, when a page that cannot be printed under the specified print condition is generated and the substitute output condition determination unit 104 performs the substitute output condition determination process, first, whether or not substitute printing is performed on the previous page. Is determined (step S201). If alternative printing is not performed for the previous page, the alternative output condition for the page is determined according to the set “alternative mode” (step S202). On the other hand, when alternative printing is performed on the previous page, a command to cancel printing of the page is output. This command is transmitted to the job control unit 105, and under the control of the job control unit 105, printing of the page is canceled and processing of the next page is executed. When pages that cannot be printed under the specified printing conditions are continuously included in the print job as in the fourth modification, the alternative printing is performed only on the first page of these consecutive pages, and the remaining pages are printed. By avoiding alternate printing for pages, it is possible to save resources by reducing paper consumption.

  The above-described embodiment and its modifications are examples of an application of the present invention, and the present invention is not limited to the above-described embodiment as it is, and the gist of the present invention is not limited thereto. Various modifications and changes can be made without departing from the scope of the invention.
