<Print job control system>
Next, a print job control system for performing printing in the present embodiment will be described. Note that the print processing of this print job control system is executed by the above-described print control program. These may be print servers that are executed by a single host computer, or may be print systems that span a plurality of host computers. The embodiment of the present invention will be described with a single print server. However, the present invention is not limited to the server spool system that spools a job on a server machine, and a host computer that is a client machine in the print system holds a job, Under the schedule management of the job in the print system by the server machine, a client spool system that transmits the job to the output device may be used, and the proxy printing process of the present invention can be performed.

<Print system software configuration>
Next, the software configuration of the print system will be described. This software configuration is included in the above-described print control program.

  These may be print servers that are executed by a single host computer, or may be print systems that span a plurality of host computers. The embodiment of the present invention will be described with a single print server. However, the present invention is not limited to the server spool method in which a print job is spooled on a server machine. The client spool method may be used in which a print job is transmitted to the printer under the schedule management of the print job in the print system by the server machine.

  More specifically, FIG. 6A is a diagram illustrating an example of a software configuration in the server 101. The arrows between the components indicate how a print job including a drawing command issued from an application is processed. The software configuration shown in each block is executed by the CPU 200 in FIG. 2 to realize a desired function.

  Normally, when a general application program 601 such as Microsoft® Word receives a print instruction from a user, it generates a series of drawing commands via the OS. The drawing command generated via the OS is passed to the PDL driver 602. The PDL driver 602 generates a print job including a PDL file that can be interpreted by the network printers 102 and 103 based on the series of drawing commands, and the spooler 603. To pass. In the following description, a PDL driver will be described as an example. However, the present invention is not limited to this. For example, band-based display data (also referred to as BDL (Band description Language)) or a compressed bitmap is created. Needless to say, the present invention can also be applied to a printer driver.

  The spooler 603 takes a procedure of transferring a print job to the port monitor 604 selected and instructed by the user via the user interface and transmitting the print job to the network printers 102 and 103 (arrow a). Here, the description will proceed assuming that the user has designated the port monitor 604 for proxy printing in advance (hereinafter abbreviated as job control port monitor) and instructed printing.

  In addition, print setting information such as a paper size and a staple instruction set via the printer driver interface is also transmitted to the job control port monitor 604.

  The job control port monitor 604 does not directly transmit the print job to the network printers 102 and 103 but transmits it to the print service 605 for proxy printing (hereinafter referred to as job control print service) (arrow b). The job control print service 605 has a function of managing the transferred print job and device status. Especially when the network printer and the data transfer source are connected by peer-to-peer and directly submit a print job to the network printer, information such as the device status and print job status notified from the network printer can be managed. A function of giving a predetermined command to the printer is also provided. This corresponds to a function for managing device information and print job information of a plurality of network printers 102 and 103.

  The print job is transferred to the network printer 102 or the network printer 103 while holding a copy of the print job based on the proxy print function of the print job (arrows c and d).

  The print manager 609 is a program that provides a user interface for the user to check the state of the print print job in the job control print service 605 and to operate the print print job. The print manager 609 exchanges information and instructions with the job control print service 605 via a software interface (API: Application Program Interface) of the job control print service 605.

  It mainly has a function of acquiring status information of the network printers 102 and 103 managed by the job control print service 605 as an event. Event notification types include warnings when the amount of toner is low, communication failure between the client and the device, memory shortage, full output tray, and other error / warning information notifications. Notification of normal information is assumed. Here, the job control print service 605 has a function of monitoring statuses such as a power control state and failure information (paper jam) during printing execution of each network printer that can communicate via a network.

  More specifically, the print manager 609 issues an event specifying a device to the job control print service 605, and the job control print service 605 monitors the status of the device based on the issued event. Based on the result, the print manager 609 is notified.

  The management console 610 can monitor the entire server 101 or the clients 107 and 108 by exchanging information and instructions with the job control print service 605 via an API for software access.

  The job control print service 605 clearly indicates a function for communicating with the network printers 102 and 103 by using the device information control module 606 and obtaining information regarding a print job and an operation state in each printer. The job control print service 605 may be included.

  On the other hand, when the print function that is installed as a standard in a general operating system is used without using the proxy printing function, the PDL file generated by the PDL printer driver 602 is transferred from the spooler 603 to the job control port monitor 608. (Arrow e), the data is transferred to the network printer 102 or the network printer 103 (arrow f).

  Next, a modification of the system described with reference to FIG. 6A will be described with reference to FIG. 6B. FIG. 6B shows a case where the functions necessary for the proxy printing are shared by the client 104 and the server 101 and are realized in cooperation with each other. Specifically, the flow of data when the print server 101 performs scheduling for print job information created by the client 104 and registered in the print queue is shown. In addition, the same structure as FIG. 6A is represented with the same code | symbol.

  In the system of FIG. 6B, the client 104 without the management console 610 or the device information control module 606 and the server 101 having them cooperate to manage the device information of the network printer. The server 101 also has a job control server 612 and communicates with the network printers 102 and 103 using the device information control module 606 to obtain information on print jobs and operation states in each printer, Or do. The acquired information can be transferred to the job control print service 605. The job control server 612 basically has the same functions as the job control print service 605, and logically shares print job information with the job control print service 605.

  Note that the software configuration of the printing system is not limited to FIGS. 6A and 6B, and the present invention can be realized by various other configurations. For example, the client may include only the configuration from the application 601 to the job control support monitor 604, and the server 101 may include the job control print service 605, the print manager 609, the management console 610, and the device information control module 606.

<First Embodiment>
The first embodiment of the present invention will be described with reference to the sequence diagram of FIG. 7 and the flowchart of FIG. In FIG. 7, the print server 101 will be described as an example, but various forms such as FIGS. 6A and 6B described above are assumed as the system form to which the present invention is applied. Any information processing apparatus having the functions described above can be applied.

  FIG. 7 is a diagram illustrating a procedure between the print server 101 and the printers 102 and 103 in the print system that implements the proxy printing process according to the embodiment of the present invention.

  The print server 101 transmits a print job received from the application software to the printer 102 according to a user instruction. The printer 102 starts printing the job immediately after reception. Actually, the job is transferred to the printer via the job control print service 605 described with reference to FIGS. 6A and 6B.

  At this time, if the printer 102 does not finish printing the job, a state in which an error immediately occurs regardless of the print state of the previous page, for example, if the next page of data is expanded and the paper feed preparation is started. When the output device (printer 102) immediately enters a state of no paper for detecting a failure, the print server 101 sends a device failure notification and a job status notification from the printer 102 by event notification. receive.

  At this time, since the printer 102 is still printing the previous page, it is not possible to correctly determine the number of impressions that have been printed immediately after the status notification. Here, when the number of impressions is defined, it indicates the number of printed logical surfaces (logical pages), not the number of papers that have been output. For example, if the number of impressions is defined, one logical page is printed on one page of a paper medium, and in the case of double-sided printing, two pages of impressions are counted for one paper medium.

  In addition, the output device (printer 102) has already notified that the status of the device has failed and that the job has been stopped due to the failure, such as an interaction that requires user intervention, for example. There is no means for the printer 101 to know that printing is continuing.

  Upon receiving the failure notification, the printer 101 waits for a specific time for each model and each state, and after a certain time has elapsed, acquires the number of impressions for which the printer 102 has stopped printing, Display the number of completed impressions in a changeable form. By displaying the number of impressions in a form that can be changed, even if the correct number of impressions is not obtained, it can be changed based on user confirmation, and proxy printing that prevents more reliable double printing is possible. Can be realized.

  Next, a succeeding job is created based on the number of impressions that have been correctly acquired and printing has been completed, and proxy printing is performed on the 103 printer. Although the embodiment will be described with the number of impressions, the procedure of the present invention can be similarly applied even with the number of impressions.

  The flowchart in FIG. 8 shows processing performed by the job control print service 605 and the device information control module 605 in the print server 101 that executes proxy printing processing of the present invention.

  The process of the print server 101 that executes the proxy printing process of the present invention will be described in detail with reference to FIG.

  After the job control print service 605 on the print server 101 transfers the job to the printer 102 and before confirming the end of the job, the printer 102 may not be able to continue the printing process such as running out of consumables such as toner (failure). The proxy printing process of the present invention is started from the time of detection.

  First, in step S802, it is determined whether it is a device / job status notification. In step s803, the job control print service 605 determines whether there is a job transmitted to the device that has received the status notification.

  If there is a job transmitted to the device that has received the status notification, the process advances to step S804 to acquire waiting time information for acquiring the number of impressions that have been printed for the type of the device in which the failure has occurred. The type may be the model of the printer device or the printer model name, or the same model but different versions may be used as the type. In addition, the device type may be acquired from the device together with the status notification indicating the failure, or the attribute that the logical printer corresponding to the device managed in the job control print service 605 has. The information of the type may be acquired.

  FIG. 9 shows an example of a table for specifying the waiting time for each type of printer device and corresponding to various states in each type. The table in FIG. 9 may be stored anywhere as long as the job control print service 605 can be referred to. The waiting time information is acquired from the setting information shown in FIG. In this embodiment, the waiting time for each model will be described. However, if the acquired state is not a paper, for example, a state in which printing is stopped after jamming is stopped, the waiting time is determined. The waiting time may be properly used for each state. In addition, the waiting time may be included in FIG. 9 for each model and for each failure state.

  In step S805, the job control print service 605 waits for acquisition of job information until the waiting time for each device elapses. This waiting method may enter a loop, and any method may be used as long as the program can wait for a certain period of time, such as a wait function provided by the OS or a timer.

  Next, after waiting processing based on the table of FIG. 9 in S805, the number of impressions that have been printed for the job stopped due to the failure of the printer 102 is acquired in S806, and the number of completed impressions is displayed in S807. Control to display on. If the function using the number of impressions is not set for the failed device (logical printer corresponding to the device), the correct number of impressions is displayed and the flow of the present invention is terminated. If partial proxy printing is set, partial proxy printing processing is started in step S809.

  In S810, based on the number of impressions for which printing has been completed, a proxy job to be printed is generated from the next impression (in the case of double-sided printing, from the first page of physical paper including an unprinted page), and the proxy job is generated. Start the printing process. In this case, the substitution job for executing substitution printing may be a job in which print page designation is added to the same PDL data, for example, data in an intermediate file format that does not depend on the output device. Alternatively, the job control print service 605 may store in advance, and a PDL job newly including only necessary pages may be recreated and used as a substitute job. In the present invention, there is no particular dependency on the proxy job creation method. When the subsequent job is generated, in step S811, the 605 print job control service individually deletes the jobs that are stopped in the printer 102, and in step S813, transmits the substitute job to the 103 printer. End proxy printing.

  8, the number of impressions of the printing apparatus can be acquired after waiting based on the waiting time corresponding to the type of the printing apparatus in which the failure has occurred, and proxy processing is performed according to the acquired number of impressions. Therefore, it is possible to prevent the printed matter from being output twice in a network printing environment in which various types of output devices are mixed. Even if the information processing device manages a device that notifies the host of a change in the status of the output device or a change in the status of the job before the job execution is completely stopped, it changes during the job execution. It is possible to perform partial proxy printing so that the information to be obtained is correctly acquired and the output of each printer is not double-printed.

<Second Embodiment>
In the first embodiment, the number of impressions has been described as an example. However, in the sense of acquiring the printed status, the number of impressions is not limited to the number of impressions. The printing process based on FIGS. 7, 8, and 9 may be performed.

<Third Embodiment>
In the first and second embodiments, the standby time setting information of FIG. 9 has been described as being fixedly held in the job control print service 605 in advance, but the standby time setting information portion of FIG. 9 is updated. If it is configured so that it can be performed, the processing of the flowchart of FIG. 8 can be accurately processed even for a device of a newly released type.

  As a mechanism for updating the table shown in FIG. 9, for example, a new information file may be read by the job control print service 605 and the old table in FIG. 9 may be rewritten.
