  The data structure of the job, print queue data, and hold queue data of the digital printing press 102 according to the first embodiment will be described with reference to FIG.

  First, the data structure of the job will be described with reference to FIG. A job input to the digital printing press 102 has a structure of an entry 511 as shown in FIG. 5 (A). There are as many entries 511 as the number of jobs input to the digital printing machine 102 and processed. The entry 511 includes a job ID 511a, a print attribute 511b, print data 511c, and the like. The job ID 511a in the entry 511 is a unique ID, and is used by the digital printing machine 102 to identify and identify the job. The print attribute 511b in the entry 511 stores the print attribute defined in the job. As a print attribute, a user name who has input the job, a size of a sheet to be fed, a media type, and the number of pages are described. The print data 511c in the entry stores print data which is data describing an image drawn on a print sheet.

  Next, the data structure of the print queue data will be described with reference to FIG. When a job is input to the print queue, the print queue buffer 521 manages the job. When a job is input while there are no jobs in the print queue, the job is registered in queue 1 of print queue buffer 521. Next, when a job is input, it is stacked as registered in the queue 2. Printing is basically performed in order from the jobs stacked in the queue 1. When printing is completed, the job is deleted from the print queue buffer 521, so the jobs in the print queue buffer 521 move up. Then, the job stacked in the queue 1 is printed. Although only five queues are shown in FIG. 5B, an appropriate number of queues are prepared in consideration of the memory capacity of the digital printing machine 102 and the print processing speed.

  The attributes of the job registered in each print queue are managed by the print queue job attribute table. In FIG. 5B, the print queue job attribute table 522 corresponding to the job is registered in the queue 1, and the print queue job attribute table 523 corresponding to the job is registered in the queue 5. In actuality, there are as many as the number of queues of the print queue buffer 521. The print queue job attribute table 522 will be described in detail below.

  The print queue job attribute table 522 includes a job ID 522a which is an ID for identifying a job, a flag 522b for identifying a medium mismatch determination result, and a flag 522c for identifying whether or not it is a target of a suspend process. Be done.

  Details of the media mismatch determination will be described later with reference to FIG. The print queue job attribute table 522 has no actual job. In the present embodiment, the print queue job attribute table 522 is described on the assumption that the actual state of the job does not exist, but the actual state of the job may exist by copying or the like. A job ID 511 a having the same value as the value of the job ID 522 a is searched from among a plurality of entries 511. Then, the print attribute 511b and the print data 511c of the entry 511 specified from the job ID 511a having the same value as the value of the job ID 522a are acquired.

  Subsequently, the data structure of the hold queue data will be described with reference to FIG. When a print execution instruction is given to print data managed by the hold queue buffer 531, the print data is transferred to the print queue buffer 521. When a job is input to the hold queue, the job is entered in the hold queue buffer 531. The hold queue buffer 531 is a storage area of a stored job managed by the job hold function program. The job to be stored received from the external apparatus is stored in the hold queue buffer 531 together with the print setting. The structure of the hold queue buffer 531 is the same as that of the print queue buffer 521, so detailed description will be omitted.

  The attributes of jobs registered in each hold queue are managed by the hold queue job attribute table. In FIG. 5C, the hold queue job attribute table 532 corresponding to the job is registered in the queue 1, and the hold queue job attribute table 533 corresponding to the job is registered in the queue 5. In actuality, there are as many as the number of queues of the hold queue buffer 531. The hold queue job attribute table 532 will be described in detail below.

  The hold queue job attribute table 532 includes a job ID 532a which is an ID for identifying a job, and a flag 532b for identifying a media mismatch determination result. The hold queue job attribute table 532 has no actual job. In the present embodiment, the hold queue job attribute table 532 will be described on the assumption that the actual state of the job does not exist, but the actual state of the job may exist by copying or the like. A job ID 511a having the same value as the job ID 532a is searched from among a plurality of entries 511. Then, the print attribute 511b and the print data 511c of the entry 511 specified from the job ID 511a having the same value as the value of the job ID 532a are acquired.

  Next, a process from job submission to print queue buffer 521 or hold queue buffer 531 will be described. This process is achieved by the CPU 212 of the controller unit 205 executing the job hold function program read from the ROM 207 or the HDD 209 and expanded in the RAM 208.

  First, the user inputs a job to perform print processing and the like on the digital printer 102. Then, the designated value of the queue relating to whether the job for which storage in the print queue buffer 521 is specified or the job for which storage in the hold queue buffer 531 is specified is recorded as a job attribute. After receiving the job submitted by the user, a unique ID is generated and assigned to the job. Then, one entry 511 is created in the job for one job. The generated job ID is input to the job ID 511a in the entry 511, the print attribute of the received job is input to the print attribute 511b in the entry 511, and the received print data is input to the print data 511c in the entry 511.

  Next, the queue specification value described above is read, and if the queue specification value is a print queue, the queue is stacked in the print queue buffer 521. On the other hand, if the designated value of the queue is the hold queue, it is stacked in the queue of the hold queue buffer 531.

  When stacking in the queue of the print queue buffer 521, one print queue job attribute table 522 shown in FIG. 5B is generated for each job. Then, the job ID is registered in the job ID 522 a of the print queue job attribute table 522.

  On the other hand, when stacking in the queue of the hold queue buffer 531, one hold queue job attribute table 532 shown in FIG. 5C is generated for each job. Then, the job ID is registered in the job ID 532 a of the hold queue job attribute table 532.

  The operation of the configuration according to the present embodiment will be described below.

  The media mismatch determination process is started in a state where the screen shown in FIG. 14A is displayed on the display unit of the operation unit 204.

  An example of the operation screen of the job hold function displayed on the operation unit 204 in the digital printing press 102 according to the first embodiment will be described with reference to FIG. The screen includes a plurality of display areas, a plurality of operation buttons, and the like. Hereinafter, important points in describing the first embodiment will be described. The job hold function is a function of storing data to be printed in the HDD 209 of the digital printing machine 102 until a print instruction is issued from the user, and then performing printing in accordance with data for which the user has received a print instruction. Note that the digital printer 102 can store a plurality of print job data in the HDD 209 by the job hold function. This job hold function allows the user to select a print job from among a plurality of print jobs stored in the HDD 209 and specify an execution order, so that printing can be performed regardless of the order input to the HDD 209.

  The hold job list 1402 is an area for displaying a list of print jobs stored in the above-mentioned hold queue buffer 531 in the digital printing press 102. In the example of FIG. 14A, six print jobs are displayed. The digital printing press 102 can store more print jobs than the number that can be simultaneously displayed in the hold job list 1402 in the HDD 209. For example, when seven or more print jobs are stored, the user can sequentially display all the stored print jobs in the hold job list 1402 by touching or pressing the scroll buttons 1408 and 1409. In the print job displayed in the hold job list 1402, a job name 1404, a user name 1405, and a date / time field 1406 indicating the date and time when the print job is stored in the digital printing device 102 are displayed.

  The user operating the job hold screen identifies the user's own job by looking at the user name (operator name) 1405, and selects a job to be printed.

  Here, when the user selects an object by pressing or touching the part of the print job displayed in the hold job list 1402 with a finger or the like, the print job is selected, that is, the print job to be printed It will be in the state of being selected.

  The example of FIG. 14B shows a display example immediately after the operator A operates the operation screen of the job hold function displayed on the operation unit 204 and selects a print job. Here, the operator A selects JobA, JobD, and JobE in order, and three jobs are selected. The job in the selected state is indicated by a selection mark (1421, 1422, 1423) on the left of the field of the job name, and a numerical value indicating the selected order is given. Reference numeral 1424 denotes the last selected Job E, which is highlighted. This indicates that the hold job list 1402 is currently in the selected state.

  A print job list 1403 is a print job for which print processing has been started in the digital printer 102 or a print job waiting for the start of print processing. In addition, it is an area for displaying a list of print jobs stored in the print queue buffer 521 described above. The waiting time 1414 indicates an approximate waiting time until print processing for the print job stored in the print queue buffer 521 is started.

  In the example of FIG. 14B, the print job (status: printing) for which print processing has been started is JobX. On the other hand, the print job (status: waiting) waiting for the start of print processing is JobY.

  The detail button 1411 is a button for transitioning to a screen for confirming the details of the print job in the selected state in the hold job list 1402. In the example of FIG. 14B, when the detail button 1411 is pressed in a state where JobE is selected last, confirmation of detailed information of JobE becomes possible.

  The print start button 1412 is a button for instructing start of print processing of the print job selected in the hold job list 1402. When the print start button 1412 is pressed in a state where a print job is selected from among the print jobs displayed in the hold job list 1402, the selected print job is displayed in the print job list 1403 and is waiting for print processing. It becomes a state. The cancel button 1413 is a button for stopping the execution of the print job in a state where the print processing has been started by the print start button 1412.

  A media mismatch determination button 1407 is a button for performing media mismatch determination on the print job selected in the hold job list 1402. The media mismatch determination button 1407 may be grayed out so that it can not be selected if there is no print job selected in the hold job list 1402. In the example of FIG. 14B, the media mismatch determination is performed for each of Job A, Job D, and Job E in the selected state.

  Details of a series of processes related to the media mismatch determination in the first embodiment with respect to the job stacked in the hold queue buffer 531 will be described using the flowchart shown in FIG. This process is achieved by the CPU 212 of the controller unit 205 executing the UI function program read from the ROM 207 or the HDD 209 and expanded in the RAM 208. Note that there is a job stacked in the hold queue buffer 531, the hold job list 1402 is displayed on the operation unit 204, and the process of the flowchart shown in FIG. 6 is started with the job already selected.

  In step S601, the CPU 212 waits for a user operation on the screen illustrated in FIG. 14A displayed on the operation unit 204. Here, the process remains at S601 until some operation is performed by the user. If the user performs some operation on the operation unit 204, the process advances to step S602.

  In step S602, the CPU 212 determines whether the media mismatch determination button 1407 is pressed by the operation. If it is determined that the media mismatch determination button 1407 has been pressed, the process proceeds to S700. When the print job is not selected, the medium mismatch determination button 1407 may be grayed out and can not be pressed. If media mismatch determination is performed only for the selected print job, the process does not advance to S700 even if the media mismatch determination button 1407 is pressed if the print job is not in the selected state. May be On the other hand, media mismatch determination may be performed on all jobs stacked in the hold queue buffer 531 by pressing the media mismatch determination button 1407.

  In S700, the CPU 212 executes media mismatch determination processing. The details of the media mismatch determination process in S700 will be described later with reference to FIG.

  After the media mismatch determination process is performed in S700, the process proceeds to S1000. In S1000, the CPU 212 executes a process of notifying the media mismatch determination result. The details of the notification process of the media mismatch determination result in S1000 will be described later with reference to FIG.

  After the notification process of the media mismatch determination result is executed in S1000, the process returns to S601.

  On the other hand, if it is determined that the medium mismatch determination button 1407 is not pressed as a result of the determination in S602, the process proceeds to S603.

  In step S603, the CPU 212 determines whether the sheet setting button 1410 in FIG. 14 is pressed by an operation by the user. When the job is not selected, the sheet setting button 1410 is grayed out and can not be pressed. Also, for a job in which no media mismatch (sheet type mismatch) has occurred, the sheet setting button 1410 may be grayed out and can not be pressed even if the job is in a selected state. That is, even if there is no remaining sheet amount, if the sheet type mismatch does not occur, the sheet setting button 1410 may be grayed out and can not be pressed.

  If it is determined that the sheet setting button 1410 is pressed as a result of the determination in S603, the process proceeds to S1100. If the print job is not selected, the process may not advance to S1100 even if the sheet setting button 1410 is pressed.

  In step S1100, the CPU 212 executes processing relating to setting of a sheet used in the selected job. The details of the sheet setting process in step S1100 will be described later with reference to FIG. After the sheet setting process is performed in S1100, the process returns to S601. After the sheet setting process is performed in step S1100, the process proceeds to step S700 instead of returning to step S601, and the medium mismatch determination process is executed by replacing the sheet used in the job with the sheet set in step S1100. Good.

  On the other hand, if it is determined NO in S603, the process proceeds to S604. In step S604, the CPU 212 determines whether the print start button 1412 is pressed by an operation by the user.

  If it is determined that the print start button 1412 is pressed, the processing proceeds to step S605. If the job is not selected, the print start button 1412 is grayed out and can not be pressed.

  In step S605, the CPU 212 registers, in the print queue buffer 521, the job selected from the hold job list 1402 in FIG. At this time, the job registered in the print queue buffer 521 is displayed in the print job list 1403 shown in FIG. 14B and is in a print processing waiting state. After the job is registered in the print queue buffer 521 in S605, the process returns to S601.

  On the other hand, if it is determined NO in S604, the process proceeds to S606. At S606, the CPU 212 executes other processing according to the operation by the user. In the process of S606, for example, a job for which the media mismatch determination has been performed once is selected, and the detail button 1411 in FIG. 14 is pressed to transition to a screen for calling the details of the job in the selected state. Processing is conceivable.

  A flowchart for describing the details of S700 of FIG. 6 which is the media mismatch determination process according to the first embodiment is shown in FIG. This process is achieved by the CPU 212 of the controller unit 205 executing the media mismatch determination function program read from the ROM 207 or the HDD 209 and expanded in the RAM 208. The media mismatch determination process according to the first embodiment in S700 is performed in response to pressing of the media mismatch determination button 1407. Also, in response to pressing the media mismatch determination button 1407 again, the media mismatch determination is performed again, and the determination result is updated.

  In the first embodiment, of the print jobs displayed in the hold job list 1402, the process to be described below for the print job selected by the user is advanced. Here, although the print job selected by the user is targeted, the present invention is not limited to this, and all the print jobs stacked in the hold queue buffer 531 may be processed in the following description.

  First, in step S701, the CPU 212 determines whether the number of print jobs to be subjected to media mismatch determination is one or more. If it is determined in step S701 that the number of print jobs to be subjected to the media mismatch determination is one or more, the process advances to step S702. On the other hand, if it is determined NO in S701, the media mismatch determination process S700 in FIG. 7 is ended, and the process proceeds to S1000 in FIG.

  Then, in step S702, the CPU 212 determines whether the media mismatch determination has been completed for all print jobs to be subjected to the media mismatch determination. If it is determined that the media mismatch determination is not yet completed for all print jobs to be subjected to the media mismatch determination, the process advances to step S703. On the other hand, if it is determined YES in S702, the media mismatch determination processing S700 ends, and the process proceeds to S1000 in FIG.

  In step S703, the CPU 212 determines one print job to be subjected to media mismatch determination, and proceeds to step S704. In step S704, the CPU 212 acquires information on whether the method of determining the sheet feed tray used in the print job determined in step S703 as a medium mismatch determination target is sheet type designation or sheet feed tray designation. Go to S705.

  In step S705, the CPU 212 determines whether the method of determining the sheet feed tray used in the print job is sheet type designation or sheet feed tray designation. In a print job for sheet type designation, the CPU 212 instructs the media management unit 211 to refer to a sheet management table as shown in FIG.

  An example of a sheet management table for managing information of sheets stored in each paper feed tray in the digital printing machine 102 will be described with reference to FIG. The sheet management table is stored in the HDD 209 and referred to by the CPU 212. In the example shown in FIG. 17A, for each of the ten paper feed trays provided in the digital printing machine 102, information on the size 1712, the media type 1713, and the remaining amount 1714 is managed using the paper feed tray ID 1711 as a key. It is done. The remaining amount of sheets is detected by a sensor provided at each sheet feeding stage.

  For example, 1701 indicates that the size of the sheet stored in the sheet feeding stage (ID = 1) is A4, the media type is plain paper 1, and the remaining amount is 3. The numerical value indicated by the remaining amount 1714 has the following meaning. 3: Full (100%), 2: Small remaining (25%), 1: Very small remaining (less than 5%), 0: No remaining (0%). The accuracy of the remaining amount detection of the sheet can be made finer by increasing the accuracy of the remaining amount sensor. However, in the digital printing press 102 according to the first embodiment, the remaining amount detection of the above specification is performed. For example, full (100%) is a state in which 3000 sheets are stored in a sheet feeding stage capable of storing 3000 sheets. The small remaining amount (25%) is a state in which 750 sheets are stored in the sheet feeding stage capable of storing 3000 sheets. The extremely small amount (less than 5%) of the remaining amount is a state in which less than 150 sheets are stored in a sheet feeding stage capable of storing 3000 sheets. “No remaining amount (0%)” means that no sheet is stored in the sheet feeding tray capable of storing 3000 sheets, that is, 0 sheet. Thus, the remaining amount of sheets stored in each sheet feeding stage can be detected in three stages by the sensors provided in each sheet feeding stage.

  For example, a print job for sheet type specification using A4 color paper (red) refers to the sheet management table shown in FIG. 17A and determines whether A4 color paper (red) is registered in one of the paper feed stages. Do. Then, as a result of determining that the size of the sheet stored in the sheet feed tray (ID = 2) is A4 and the media type is colored paper (red), the sheet feed tray (ID = 2) is the sheet feed destination. It is determined as On the other hand, in the case of a print job of sheet feed stage designation which designates a sheet feed stage (ID = 3), the sheet management table of FIG. A3 plain paper 1 "is fed.

  If it is determined that the print job is a sheet type designation job as a result of the determination in S 705, the process proceeds to S 800. On the other hand, if it is determined that the print job is a job specifying a paper feed stage, the process advances to step S900. Details of the process in step S800 and the process in step S900 will be described later with reference to FIGS. 8 and 9, respectively. When the process in S800 or S900 is completed, the process returns to S702.

  A flowchart for describing S800 of FIG. 7 which is media mismatch determination processing performed when the print job to be subjected to media mismatch determination is a job of sheet type designation is shown in FIG. This process is achieved by the CPU 212 of the controller unit 205 executing the media mismatch determination function program read from the ROM 207 or the HDD 209 and expanded in the RAM 208.

  In step S <b> 801, the CPU 212 acquires the type of sheet set in each paper feed tray provided in the digital printing apparatus 102 and information on the remaining amount of sheets. The process of S801 is performed by the CPU 212 instructing the media management unit 211 to refer to, for example, the sheet management table of FIG. 17A described above. In step S802, the CPU 212 reads the print job stored in the hold queue buffer 531 regarding the print job to be subjected to the media mismatch determination. Then, among the sheet types used in the print job as shown in FIG. 17B, the number of sheet types designated by the sheet type is acquired.

  FIG. 17B is a diagram for explaining sheet information used by each job of JobA, JobD, and JobE shown in FIG. 14B. The information shown here is held by storing the print setting at the same time when the job hold function program stores the print job in the hold queue buffer 531. The sheet information used by the print job is included in the print setting. JobA indicates using a total of two types of sheets: a sheet with a size of A4 and a media type of "plain paper 1" and a sheet with a size of A4 and a media type of "double-sided coated paper 1" . In addition, JobD indicates that a total of two types of sheets, a sheet with a size of LTR and a media type of “plain paper 1” and a sheet with a size of 11 × 17 and a media type of “plain paper 1”, are used. There is. Similarly, Job E is a sheet of which the size is A4 and the media type is "plain paper 1", a sheet of which the size is A4 and the media type is "colored paper (red)", and a size of A3 and the media type is "both sides It shows that three types of sheets of coated paper 2 "are used. The sheet type is determined by the combination of the size and the media type.

  Next, in step S 803, the CPU 212 sets two types of flags (Flag A and Flag B) for holding the result of the media mismatch determination by the number of sheet types acquired in step S 802 and performs initialization processing. Here, Flag A is a flag for holding the result of determination as to whether or not the attribute information of the sheet used in the print job is registered in any of the paper feed stages, and is stored in the RAM 208. On the other hand, Flag B is a flag for holding the result of determination as to whether or not there is a remaining amount of sheets to be used in a print job, and is stored in the RAM 208. When Flag A is true, it indicates that the print job designates a media mismatch (sheet type mismatch) state, that is, a sheet type not set in any sheet feed stage. On the other hand, when Flag B is true, it indicates that the medium is mismatched (no remaining sheet amount), that is, the remaining sheet amount of the sheet type used in the print job is zero. Note that the value of Flag A is initialized as true (mismatch), and the value of Flag B as true (no remaining amount).

  Next, in step S804, the CPU 212 determines whether the media mismatch determination process has been completed for all sheet types used in the print job to be subjected to the media mismatch determination. If it is determined that the process is not completed for all sheet types, the process advances to step S805. In step S805, the CPU 212 determines one sheet type to be subjected to the media mismatch determination in the print job, and the processing proceeds to step S806.

  In step S806, the CPU 212 determines whether the media mismatch determination process has been completed for all sheet feeding trays included in the digital printing machine 102. If it is determined that there is a sheet feeding stage for which the medium mismatch determination process has not been performed yet, the process advances to step S807. In step S807, the CPU 212 determines a paper feed stage to be subjected to the next media mismatch determination, and proceeds to step S808.

  In step S808, the CPU 212 determines whether the sheet type determined in step S805 to be subjected to the media mismatch determination matches the sheet type set and registered in the paper feed stage to be subjected to the media mismatch determination determined in step S807. Determine If it is determined that these match, the processing proceeds to step S809. On the other hand, if NO is determined in S808, the process returns to S806 and the subsequent processes are advanced.

  In step S809, the CPU 212 saves the value of Flag A in association with the print job as "false (match)" indicating that the print job designates the sheet type registered in the paper feed tray. The process advances to step S <b> 810, and the CPU 212 determines whether there is a remaining amount of sheets in the paper feed stage to be subjected to the media mismatch determination determined in step S <b> 807. If it is determined that there is a remaining amount of sheets, the process advances to step S811. In step S811, the CPU 212 stores the value of Flag B as "false (remaining amount)" indicating that there is a sheet remaining amount of the sheet type used in the print job, and stores the value in association with the print job. Advance the processing of On the other hand, if it is determined NO in S810, the process returns to S806 to advance the subsequent processing.

  If it is determined in step S806 that the media mismatch determination process is completed for all sheet feeding trays, the process returns to step S804 to advance the subsequent processes. When the media mismatch determination is completed for all sheet types used in the print job to be subjected to the media mismatch determination as a result of the determination in S804, the media mismatch determination process S800 performed when the sheet type is specified is performed. It completes and returns to S702 of FIG. The above is the detailed description of the media mismatch determination processing in the case of sheet type designation in S800 of FIG.

  On the other hand, if it is determined that the print job is a job designating a sheet feed stage as a result of the determination in S705 of FIG. 7, the process proceeds to S900. FIG. 9 shows a flowchart for explaining S900 of FIG. 7 which is media mismatch determination processing performed when the print job to be subjected to media mismatch determination is a job for sheet feed stage designation. This process is achieved by the CPU 212 of the controller unit 205 executing the media mismatch determination function program read from the ROM 207 or the HDD 209 and expanded in the RAM 208.

  In step S <b> 901, the CPU 212 controls the sheet feeding stage among the sheet types used in the print job as information on the sheet used in the print job as illustrated in FIG. Get the number of specified sheet types. Next, in step S902, the CPU 212 performs initialization processing by setting a flag for holding the result of the media mismatch determination (determination of remaining sheet amount) by the number of sheet types acquired in step S901.

  Here, the Flag is a flag for holding the result of determination as to whether or not there is a remaining amount of sheets to be used in the print job, and is stored in the RAM 208. If the value of Flag is true (no remaining amount), it indicates that the medium is mismatched, that is, the remaining amount of the sheet type used in the print job is zero. The value of Flag is initialized as true (no remaining amount). Note that in a job for which a sheet feed stage is specified, it is not determined whether a sheet used in the job is registered in the sheet feed stage specified by the job. Therefore, the flag for sheet type mismatch determination is not held.

  Next, in step S903, the CPU 212 determines whether the media mismatch determination (sheet remaining amount determination) process has been completed for all sheet types used in the print job to be subjected to the media mismatch determination (sheet remaining amount determination). It is determined whether or not. If it is determined that the process is not completed for all sheet types, the process advances to step S904. In step S904, the CPU 212 determines one sheet type to be subjected to media mismatch determination (sheet remaining amount determination) in the print job, and the process advances to step S905. In step S905, the CPU 212 acquires sheet remaining amount information of a sheet feed stage designated by the sheet type to be subjected to sheet remaining amount determination determined in step S904 among sheet types used in the print job. The process of S 905 is performed by the CPU 212 instructing the media management unit 211 to refer to a sheet management table as shown in FIG. 17A, for example.

  The process advances to step S906, and the CPU 212 determines whether there is a remaining amount of sheets in the sheet feed stage acquired in step S905. If it is determined that there is a remaining amount of sheets, the process advances to step S907. In step S 907, the CPU 212 stores the value of Flag as “false (remaining amount) representing that there is a remaining amount of sheets scheduled to be used in the print job” in association with the print job and returns to S 903. Proceed with the process.

  On the other hand, if NO is determined in S906, the process returns to S903, and the subsequent processes are advanced.

  If the media mismatch determination is completed for all sheet types used in the print job to be subjected to the media mismatch determination as a result of the determination in S903, the media mismatch determination process S900 performed when the paper feed stage is specified End and returns to S702 in FIG.

  The above is the detailed description of the media mismatch determination processing in the case of sheet feeding stage designation in S900 of FIG. 7.

  Next, FIG. 10 shows a flowchart of processing S1000 for notifying the hold job list 1402 of the media mismatch determination result. This process is achieved by the CPU 212 of the controller unit 205 executing the UI function program read from the ROM 207 or the HDD 209 and expanded in the RAM 208.

  In step S1001, the CPU 212 determines whether the print job for which the media mismatch has been determined is displayed in the hold job list 1402. If it is determined that the print job subjected to the media mismatch determination is displayed in the hold job list 1402, the processing proceeds to step S1002.

  In step S1002, the CPU 212 holds a flag for determining the result of sheet type mismatch determination, in which it is determined whether the sheet attribute information used in the print job subjected to the media mismatch determination is registered in any of the sheet feed stages. The value of Flag A is read from the RAM 208. Then, it is determined whether the value of Flag A is “false (match)”.

  If the value of Flag A is determined to be true (mismatch) in at least one sheet type, the print job designates a media mismatch (sheet type mismatch) state, that is, a sheet type not set in any sheet feed stage. Indicates that you are in the Therefore, in this case, the process advances to step S1003. For example, as shown in FIG. 14C, the entry of the print job in the hold job list 1402 includes the sheet type mismatch warning mark 1431 indicating the media mismatch state and the print job. Display a warning in response to The sheet type mismatch warning mark 1431 indicates that a sheet of the sheet type (size and media type) used in the print job is not set in any sheet feed stage. Then, a series of processes S1000 for notifying the media mismatch determination result are ended, and the process returns to S601 in FIG.

  On the other hand, if YES is determined in S1002, the process proceeds to S1004. In S1004, the CPU 212 reads out the value of Flag B from the RAM 208, and determines whether the value of Flag B is "false (remaining)". Note that Flag B is a flag for holding the result of the sheet remaining amount determination which determines whether there is a remaining amount of sheets scheduled to be used in the print job for which the media mismatch determination has been performed.

  If it is determined that the value of Flag B is true (no remaining amount) in at least one sheet type as a result of the determination in S1004, a media mismatch (no remaining amount) state, that is, the sheet type used in the print job Indicates that the remaining amount of the sheet is zero. Therefore, in this case, the process advances to step S1005, and for example, as shown in FIG. 14C, the entry for the print job in the hold job list 1402 has the remaining sheet non-remaining warning mark 1432 indicating the medium mismatch state. Display warning in association with the job. The sheet remaining amount warning mark 1432 indicates that the sheet used by the print job is set to the sheet feed tray, but the remaining amount is zero. Then, a series of processes S1000 for notifying the media mismatch determination result are ended, and the process returns to S601 in FIG.

  On the other hand, if YES is determined in S1004, it means that there is a remaining amount of sheets for all sheet types used in the print job. Then, a series of processes S1000 for notifying the media mismatch determination result are ended, and the process returns to S601 in FIG.

  Next, an example of the operation screen after notifying the hold job list 1402 of the result of media mismatch determination in the digital printing press 102 according to the first embodiment will be described with reference to FIG. On the other hand, FIG. 14B shows a display example immediately after the operator A operates the operation screen of the job hold function displayed on the operation unit 204 and selects a print job. In FIG. 14 (C), parts common to FIG. 14 (B) are indicated by the same symbols. Similar to FIG. 14B, in FIG. 14C, the operator A selects JobA, JobD, and JobE in order, and three jobs are selected.

  In FIG. 14C, for each of three jobs (JobA, JobD, and JobE) selected by the user, the sheet for which each print job is to be used and the sheet set for the sheet feed tray of the digital printing machine 102 are used. Matching is checked (media mismatch judgment).

  For example, in Job A, as shown in FIGS. 17A and 17B, the sheet whose print job is to be used is set to the sheet feed stage, and the remaining amount of the sheet is not zero. Therefore, neither the sheet type mismatch warning mark 1431 nor the sheet remaining amount no warning mark 1432 is displayed on Job A. In this case, when the user presses the print start button 1412, the user can know that the possibility of occurrence of a media mismatch is extremely low before instructing to start printing.

  Also, for Job D, the sheet whose print job is scheduled to be used is set to the paper feed stage as shown in FIGS. 17A and 17B, but the remaining sheet amount is zero. Exists. Specifically, the remaining amount of sheets of the size “11 × 17” and the media type “plain sheet 1” set to the “sheet feeding tray 9” is zero. Therefore, when the print start button 1412 is pressed in this state, a media mismatch (no remaining amount of sheet) occurs at the stage of feeding a sheet of size “11 × 17”, and the printing process is stopped. Therefore, the sheet D with no remaining amount warning mark 1432 is displayed on JobD. If the user recognizes that the no remaining sheet amount warning mark 1432 is displayed, an appropriate action is taken, that is, if the sheet of the size “11 × 17” and the media type “plain sheet 1” is supplied to the sheet feeding tray 9 Good.

  Further, in the case of Job E, as shown in FIG. 17A and FIG. 17B, there are sheets which are not set for any sheet feed stage, as the print job is to be used. Specifically, a sheet of size A3 and media type “double-sided coated paper 2” is not set to any paper feed stage. Therefore, a sheet type mismatch warning mark 1431 is displayed on JobE. When the user presses the detail button 1411 in the state of FIG. 14C, the sheet size and media type (1728, 1729, 1730) used by the selected Job E are displayed. Here, the media information (here, A3, double-sided coated paper) which is not set to any paper feed stage is displayed to the user, for example, by reversing and not set to any paper feed stage. A sheet can be presented. Therefore, when the user presses the print start button 1412 in this state, the user can start printing because the media mismatch (sheet type mismatch) occurs and the print job is stopped when the user attempts to feed the sheet. You can know before giving instructions. The user who confirms that the mark 1431 is displayed specifies an appropriate action, that is, another sheet feed tray (a sheet feed tray which is not determined to be used in the print job is desirable), and is identified. Change the sheet settings of the paper feed tray to size A3 and the media type to "double-sided coated paper 2". Specifically, by pressing a sheet setting button 1410 described later, a sheet feed stage which is not determined to be used in a print job is specified, and sheet settings of the sheet feed stage are changed. Furthermore, the user supplies the corresponding sheet to the sheet feed tray. If there is a sheet originally contained, the user may replace the sheet with a corresponding sheet.

  In the present embodiment, as shown in FIG. 14C, the shapes of the sheet type mismatch warning mark 1431 and the sheet remaining amount no warning mark 1432 are changed. By this, the user distinguishes whether the sheet of the job is not set to any sheet feeding tray, or whether the sheet of the job is set to any sheet feeding tray but the remaining amount is zero. It can be recognized. In this manner, when the media mismatch determination is performed, the user is prevented from stopping the print job by displaying the marks 1431 and 1432 as warnings in association with the print job in which the media mismatch may occur. Is possible.

  In the state of FIG. 14C, when the user selects JobD and presses the detail button 1411, the sheet size and media type (1726, 1727) used by JobD are displayed. Here, the CPU 212 blinks the sheet information whose remaining amount is zero. Further, the CPU 212 blinks the display of the sheet feed stage in which the sheet is set. As a result, the user can grasp the sheet information of which the remaining amount is zero for the sheet size and media type used by Job D, and the sheet feed stage thereof. As described above, even when the sheet size and the media type are displayed, the display method of the sheet information when the sheet is not set to any sheet feed stage, and the sheet information of the remaining sheet amount of the sheet being zero are displayed. Change the way of As a result, the user can distinguish whether the sheet of the displayed size and type is not set in any sheet feed tray and whether the remaining amount of the sheet is zero. Here, the media information which is not set in any of the sheet feeding stages is inverted and displayed, and the sheet information whose remaining amount is zero is displayed by blinking. The present invention is not limited to this, and the sheet type mismatch warning mark 1431 and the sheet remaining amount no warning mark 1432 may be associated with each sheet information to display a warning.

  Next, FIG. 11 shows a flowchart for explaining S1100 of FIG. 6 which is a process of setting a sheet to be used in the selected print job. This process is achieved by the CPU 212 of the controller unit 205 executing the UI function program read from the ROM 207 or the HDD 209 and expanded in the RAM 208. In the state where the mismatched sheet list screen 1501 shown in FIG. 15A is displayed on the operation unit 204 and a mismatched sheet is selected from the sheet list 1502, the processing of the flowchart shown in FIG. 11 is started.

  The mismatched sheet list screen 1501 is a screen for setting a mismatched sheet of a job in which a media mismatch has occurred. The sheet list 1502 is created by aggregating mismatched sheets of jobs in which a media mismatch (sheet type mismatch) has occurred among the sheets used in the jobs selected in the hold job list 1402. Although only the mismatched sheet is displayed in the sheet list 1502 in the example of FIG. 15A, all sheets used in the job selected in the hold job list 1402 may be displayed. In the judgment of the mismatched sheet of the job in which the media mismatch (sheet type mismatch) occurs, the value of the above-mentioned flag (FlagA) holding the result of the media mismatch judgment set for each sheet type used in the job is used. It becomes possible by referring.

  In the example of FIG. 15A, the sheet list 1502 displays information regarding the sheet of “name: Paper1, size: A4” and the sheet of “name: thick paper, size: A3”. The user can know that the sheet of “A3 thick sheet” is in the selected state, and that the sheet of “A4Paper1” is not in the selected state. Also, the sheet of “A4Paper1” is a sheet to be used in the job selected second on the hold job list 1402, and the sheet of “A3 thick sheet” is used in the job selected fourth on 1402 The user can know that it is a sheet.

  Furthermore, by displaying the sheet type mismatch warning mark 1431 in association with the sheet of “A3 thick sheet” and the sheet of “A4 Paper 1”, the user knows that a media mismatch has occurred in each sheet type. Can.

  In step S1101, the CPU 212 waits for a user operation on the screen illustrated in FIG. 15A displayed on the operation unit 204. Here, the process remains in S1101 until some operation is performed by the user. If the user performs some operation on the operation unit 204, the process advances to step S1102. Note that when the sheet is not selected, the sheet detail button 1503 and the sheet feed tray selection button 1505 in FIG. 15A are grayed out and can not be pressed.

  In step S1102, the CPU 212 determines whether the operation is an event to press the sheet feed tray selection button 1505. If it is determined that this is an event to press the sheet feed tray selection button 1505, the process proceeds to step S1200.

  In step S1200, the CPU 212 executes processing for displaying a screen for selecting a sheet feed tray, and then proceeds to step S1300. The details of the process in S1200 will be described later with reference to FIG.

  In step S1300, the CPU 212 executes the process of setting the attribute information of the sheet feed tray, and then returns to step S1100. The details of the process in S1300 will be described later with reference to FIG.

  On the other hand, if it is determined NO in S1102, the process proceeds to S1103. In step S1103, the CPU 212 determines whether the operation is an event to press the cancel button 1504. If it is determined that this is an event to press the cancel button 1504, the information set on the mismatched sheet list screen 1501 is discarded. Then, S1100 in FIG. 6, which is a process of setting a sheet used in the selected print job, is ended, and the process returns to S601 in FIG.

  On the other hand, if it is determined NO in S1103, the process proceeds to S1104. In step S1104, the CPU 212 returns to step S1101 after performing other processing according to the operation by the user. As the processing of S1104, for example, processing such as transition to a screen 1521 for calling detailed information of a sheet as shown in FIG. 15C can be considered by pressing the sheet detail button 1503. The sheet detailed information screen 1521 in FIG. 15C relates to adjustment of sheet name, size, basis weight, surface property, feature, color, and creep (displacement) correction amount as sheet attribute information, for example. The user can know the detailed information.

  Next, FIG. 12 shows a flowchart for explaining S1200 of FIG. 11 which is a process of displaying a screen for selecting a sheet feeding stage capable of setting attribute information of mismatched sheets. This process is achieved by the CPU 212 of the controller unit 205 executing the UI function program read from the ROM 207 or the HDD 209 and expanded in the RAM 208. The mismatched sheet targeted in the process at S1200 is the mismatched sheet in the selected state in the sheet list 1502 of FIG.

  In step S <b> 1201, the CPU 212 determines whether or not the determination has been completed for all sheet feeding stages in order to determine a sheet feeding stage capable of setting attribute information of mismatched sheets. If it is determined that the determination on all the sheet feed stages is not completed, the process proceeds to step S1202.

  In step S1202, the CPU 212 determines one sheet feeding stage to be subjected to determination as to whether or not the attribute information of the mismatched sheet can be set, and the process advances to step S1203.

  In step S <b> 1203, the CPU 212 acquires attribute information of the sheet set in the sheet feed tray. Specifically, the CPU 212 instructs the media management unit 211 to acquire the attribute information of the sheet set in the paper feed stage by referring to the sheet management table as shown in FIG. it can.

  Next, in step S1204, the CPU 212 determines whether the attribute information of the mismatched sheet can be set in the sheet feed stage determined in step S1202. Note that whether or not attribute information of a specific sheet can be set in the sheet feeding stage is determined depending on the combination of the media type and the sheet feeding stage to be set. For example, since the size of the sheet feeding tray 1 is smaller than that of the other sheet feeding trays, sheets larger than A4 can not be stored. Therefore, the sheet of A3 can not be set to the sheet feeding tray 1. Further, for example, since there is a portion for rolling a sheet in the transport path from the paper feed tray, it is not possible to pass a sheet having a large basis weight from the paper feed tray. Therefore, a sheet having a large basis weight can not be set to any sheet feed stage.

  As described above, there is a limitation that a specific sheet can not be fed depending on the position of the sheet feeding stage, the sheet size, or the basis weight of the sheet.

  If it is determined that the attribute information of the mismatched sheet can be set in the sheet feed stage determined in S1202 as a result of the determination in S1204, the process proceeds to S1205. On the other hand, if it is determined that the attribute information of the mismatched sheet can not be set in the sheet feed stage determined in S1202, the process proceeds to S1208.

  In step S1205, the CPU 212 determines whether there is a job using sheets stored in the paper feed tray determined in step S1202 among the jobs selected in the hold job list 1402. If it is determined not, the process proceeds to S1206. On the other hand, if it is determined that there is, the process proceeds to S1208.

  In step S1206, the CPU 212 determines whether there is a job using sheets stored in the sheet feed tray determined in step S1202 among the jobs displayed in the print job list 1403. If it is determined not, the process proceeds to S1207. On the other hand, if it is determined that there is, the process proceeds to S1208.

  In step S1207, the CPU 212 determines that the sheet feed stage determined in step S1202 can set the attribute information of the mismatched sheet, returns to step S1201, and advances the subsequent processing.

  On the other hand, in step S1208, the CPU 212 determines that the sheet feed stage determined in step S1202 can not set the attribute information of the mismatched sheet, returns to step S1301, and advances the subsequent processing.

  On the other hand, if it is determined that the determination has been completed for all the sheet feed trays as a result of the determination in S1201, the process proceeds to S1209. In step S1209, the CPU 212 causes the operation unit 204 to display a sheet feed stage selection screen 1511 shown in FIG. 15B based on the sheet feed tray determination result (S1207 and S1208) in which the attribute information of the mismatched sheet can be set. .

  After the processing in S1209, the series of processing according to S1200 in FIG. 11 is ended, and the process proceeds to S1300 in FIG.

  An example of the determination result of the sheet feed tray capable of setting the attribute information of the mismatched sheet is shown in FIG. In the case of FIG. 18, the attribute information of the sheet (mismatch sheet) to be set is “A3 thick sheet”. Further, it is assumed that the sheet A3 can not be set in the sheet feed tray 1. The selected jobs (hold jobs) to be determined in step S1205 are sequentially referred to as JobH, JobI, JobJ, and JobK. Note that JobH is a job using "A4 plain paper", JobI is a job using "A4 Paper 1", JobJ is a job using "A3 plain paper", and JobK is a job using "A3 thick paper". In addition, “A4Paper1” used in JobI and “A3 thick paper” used in JobK are not set in the paper feed stage, and thus become mismatched sheets, and the sheet type mismatch mark 1431 is displayed in association with the sheets. There is. As shown in FIG. 18, the sheet feed tray capable of setting “A3 thick sheet” is determined to be sheet feed tray 2 and sheet feed tray 3.

  Next, FIG. 13 shows a flowchart for explaining S1300 of FIG. 11 which is a process of setting the attribute information of the sheet feeding stage. This process is achieved by the CPU 212 of the controller unit 205 executing the UI function program read from the ROM 207 or the HDD 209 and expanded in the RAM 208. In the state where the sheet feed stage selection screen 1511 is displayed on the operation unit 204, the processing of the flowchart shown in FIG. 13 is started.

  In step S1301, the CPU 212 waits for the user's operation on the paper feed tray selection screen 1511 shown in FIG. 15B displayed on the operation unit 204. Here, the process remains in S1301 until some operation is performed by the user. If the user performs some operation on the operation unit 204, the process advances to step S1302. When the sheet feeding stage is not selected, the sheet detail button 1512 and the OK button 1514 in FIG. 15B are grayed out and can not be pressed. If the attribute information of the mismatched sheet can not be set, the sheet feed tray determined in S1200 of FIG. 11 is grayed out and can not be selected. In the example of FIG. 15B, the sheet feeding stages determined to be incapable of setting A3 thick sheet are the sheet feeding stage 1, the sheet feeding stage 4, the sheet feeding stage 5, and the sheet feeding stage 6. On the other hand, the sheet feed stages determined to be capable of setting A3 thick sheet are the sheet feed stage 2 and the sheet feed stage 3.

  In step S1302, the CPU 212 determines whether the operation is an event for selecting a sheet feeding stage capable of setting the attribute information of the mismatched sheet. If it is determined that the event is an event for selecting a sheet feed stage capable of setting attribute information of mismatched sheets, the process advances to step S1303. In step S1303, the selected sheet feeding tray is selected, and the process returns to step S1301. In the example of FIG. 15B, the user can know that the paper feed stage 2 determined to be capable of setting A3 thick paper is in the selected state.

  On the other hand, if NO is determined in S1302, the process proceeds to S1304. If YES in S1302, the sheet feed tray is selected in S1303, and the process returns to S1301. Therefore, if a sheet feed tray capable of setting a mismatched sheet is already selected, the process proceeds to S1304 and subsequent Processing is performed.

  In step S1304, the CPU 212 determines whether the operation is an event to press the cancel button 1513. If it is determined that this is an event to press the cancel button 1513, the information set on the sheet feed tray selection screen 1511 is discarded. Then, S1300 of FIG. 11, which is a process of setting the attribute information of the sheet feeding stage, is ended, and the process returns to S1101 of FIG.

  On the other hand, if NO is determined in S1304, the process proceeds to S1305. In step S1305, the CPU 212 determines whether the operation is an event to press the OK button 1514. If it is determined that the event is an event of pressing the OK button 1514, the process advances to step S1306.

  In step S1306, the CPU 212 sets the mismatched sheet of the job in which the media mismatch has occurred to the paper feed stage selected in step S1303. In the example of FIG. 15B, the A3 thick sheet is set to the sheet feeding stage 2 in the selected state. Then, S1300 of FIG. 11, which is a process of setting the attribute information of the sheet feeding stage, is ended, and the process returns to S1100 of FIG.

  On the other hand, if NO is determined in S1305, the process proceeds to S1307. In step S1307, the CPU 212 returns to step S1301 after performing other processing according to the user's operation. As the processing of S1307, for example, processing such as transition to a screen 1521 for calling detailed information of a sheet shown in FIG. 15C can be considered by pressing the sheet detail button 1512.

  The above is the details of the series of sheet setting processing in S1100 of FIG.

  As described above, in the first embodiment, in order to eliminate the media mismatch (the sheet type mismatch), the attribute information of the mismatched sheet is used in the selected hold job and print job when setting the sheet feed stage. It was controlled not to select the paper feed stage determined as. This causes a new media mismatch to occur and causes the printing of another job to stop, as the user erroneously changes the setting of the attribute information of the sheet feed tray used by the selected hold job or print job. Can be prevented.

  In the first embodiment, if it is determined that setting can not be performed on all the sheet feeding trays provided in the printing apparatus as a result of determining the sheet feeding tray capable of setting the attribute information of the mismatched sheet, the mismatched job The user may be further notified to release the selection state of. In that case, in S1209 of FIG. 12, the CPU 212 displays a warning screen 1601 shown in FIG. 16A instead of displaying the sheet feed stage selection screen 1511 of FIG. 15B on the operation unit 204. The warning screen 1601 allows the user to know that the job using the mismatched sheet can not be printed because it is impossible to set the sheet attribute information to be used in the mismatched job to all sheet feed trays. When a mismatched sheet is selected on the warning screen 1601 and the selection release button 1602 is pressed, it is possible to release the selected state of the mismatched job. When the selected state of the mismatched job is all canceled on the warning screen 1601 and all the held jobs in the selected state are not in the mismatched state, a notification screen 1611 shown in FIG. 16B is displayed on the operation unit 204. May be Since the attribute information of the sheet used in the hold job in the selected state is set in all sheet feeding trays by the notification screen 1611, the user can know that printing of the hold job in the selected state can be executed as it is it can.

Second Embodiment
In the first embodiment described above, when the attribute information of the mismatched sheet is set to the sheet feed stage in order to eliminate the media mismatch, the sheet feed stage determined to be used in the selected hold job and print job is The case of making it impossible to select is described.

  However, if it is determined that the selected sheet is used in the hold job and print job selected for all the sheet feed trays provided in the printing apparatus, the attribute information of the mismatched sheet is set to the sheet feed tray in order to eliminate the media mismatch. It will not be possible.

  On the other hand, since the user wants to print in order from high priority jobs, it is general to print high priority jobs first and print low priority jobs later.

  Therefore, in the second embodiment, in order to eliminate the media mismatch (the sheet type mismatch), when the attribute information of the mismatched sheet is set to the sheet feed stage, it is determined that the sheet is determined to be used in a high priority job. Make the row not selectable. On the other hand, a case will be described in which the sheet feeding tray used in the low priority job can be selected and attribute information of the mismatched sheet can be set to the sheet feeding tray.

  In the configuration of the printing system according to the second embodiment, as in the first embodiment, the digital printing device 102 and the computer 101 are connected via the network 100. In addition, a functional block diagram showing a functional configuration of the digital printing machine 102 according to the second embodiment and a hardware block diagram showing a configuration of the computer (PC) 101 according to the second embodiment are the first embodiment. Since these are the same as in FIG. A series of flowcharts for explaining the processing by the digital printing device 102 according to the second embodiment are omitted because they are similar to FIGS. 6 to 13 described in the first embodiment. In the second embodiment, the process that is different from the first embodiment is a process of determining a sheet feed stage capable of setting attribute information of a mismatched sheet.

  FIG. 19 shows a flowchart for explaining processing for displaying a screen for selecting a sheet feeding stage capable of setting attribute information of mismatched sheets in the second embodiment. This process corresponds to the process in S1200 of FIG. In the flow of FIG. 19, portions performing the same processing as the flow of FIG. 12 described in the first embodiment are assigned the same step numbers as in FIG. 12. The difference from the flow of FIG. 12 will be mainly described, and the description of the part performing the same processing as the flow of FIG. 12 will be omitted.

  If it is determined that the attribute information of the mismatched sheet can be set in the sheet feed stage determined in step S1202 as a result of the determination in step S1204, the process advances to step S1901.

  In step S1901, the CPU 212 uses the sheet stored in the sheet feed stage determined in step S1202 among the jobs selected in the hold job list 1402 and whose selection order is earlier than the mismatched job. Determine if there is. After the hold job selection order, as described in FIG. 14B, the numerical value indicating the selected order is indicated by the selection mark (1421, 1422, 1423) on the left of the job name field. It is judged.

  If it is determined in step S1901 that there is no hold job for which the selection order for using the sheets stored in the paper feed tray determined in step S1202 is earlier, the process advances to step S1206 to perform the subsequent processes. On the other hand, if it is determined that there is, the process advances to step S1208 to perform the subsequent processes.

  The above is the details of the processing that is the difference from the first embodiment in the second embodiment.

  An example of the determination result of the sheet feed tray capable of setting the attribute information of the mismatched sheet in the second embodiment is shown in FIG.

  In the case of FIG. 20, the attribute information of the sheet (mismatch sheet) to be set is “A4Paper1”. Further, it is assumed that the sheet A3 can not be set in the sheet feed tray 1. The selected jobs (hold jobs) to be determined in step S1304 are sequentially referred to as JobH, JobI, JobJ, and JobK. Note that JobH is a job using "A4 plain paper", JobI is a job using "A4 Paper 1", JobJ is a job using "A3 plain paper", and JobK is a job using "A3 thick paper". In addition, “A4Paper1” used in JobI and “A3 thick paper” used in JobK are not set in the paper feed stage, and thus become mismatched sheets, and the sheet type mismatch mark 1431 is displayed in association with the sheets. There is. Description will be made regarding the case where the medium mismatch (sheet type mismatch) is eliminated by setting “A4 Paper 1” which is a mismatch sheet of Job I as the sheet feeding stage. The hold job with higher priority than JobI is JobH. This is because JobI is the second hold job in the selection order, whereas JobH is the first hold job in the selection order. Also, print jobs have higher priority than hold jobs. That is, JobV and JobW have higher priority than JobI. As shown in FIG. 20, it is determined that the sheet feeding tray capable of setting “A4Paper1” is the sheet feeding tray 1, the sheet feeding tray 2, the sheet feeding tray 3 and the sheet feeding tray 6.

  Then, as shown in FIG. 21, “A4Paper1” can not be set for sheet feed tray 4 and sheet feed tray 5 as shown in FIG. Is displayed.

  As described above, in the second embodiment, when the attribute information of the mismatched sheet is set to the sheet feed stage, it is used in the hold job and print job having higher priority than the mismatched job in order to eliminate the sheet type mismatch. It was controlled that the sheet feeding stage determined to be not selectable.

  As a result, the user erroneously changes the setting of the attribute information of the paper feed stage used by a job having a higher priority than the mismatched job, causing a new media mismatch, and causing another job having a higher priority. It is possible to prevent the printing from stopping.

  In the second embodiment, even when the sheet feed stage determined to be used in the selected hold job when the attribute information of the mismatched sheet is set to the sheet feed stage, the priority is higher than the mismatched job. Paper feed trays used for lower jobs are now selectable. However, this is not the case. If there are other paper feed trays that are not used in the selected hold job or print job, paper feed trays determined to be used by jobs with lower priority than mismatched jobs can not be selected. Good.

  In the hold job, the high priority job and the low priority job are determined based on the selection order of the mismatched jobs, but this is not the only case. For example, if the use history of each hold job is held in the HDD 209, a job with high priority and a job with low priority may be determined based on the use history of the job.

  The present invention is not limited to the above embodiments, and various modifications (including organic combinations of the respective embodiments) are possible based on the spirit of the present invention, which are excluded from the scope of the present invention is not.

  For example, in the present embodiment, the CPU of the control unit 205 of the digital printing machine 102 has been the main body of the above-mentioned various controls, but the printing control device such as an external controller of the digital printing machine 102 and another housing Part or all of the control may be configured to be executable.

  While various examples and embodiments of the present invention have been shown and described, the spirit and scope of the present invention should not be limited to the specific descriptions in the present specification, as it is understood by those skilled in the art.

(Other embodiments)
The functions shown in the flowchart in the present embodiment can also be realized by executing software (programs) acquired via a network or various storage media on a processing device (CPU, processor) such as a computer personal computer.
