Description

The present invention stores a print job, in which relates the print job stored in the image processing apparatus and its control how Ru is executed by the image forming unit.

  Conventionally, there are printing devices that support multiple types of media (sheets), and with such printing devices, it is possible to create complex and high value-added output by using multiple types of sheets. It is. For example, high-quality sheets using coated paper are used for the front and back covers, and high-quality printing is used for the middle paper, which is used on the border pages of the content chapter. For the partition paper, colored paper is used. As another example, a high-quality sheet that can provide high-quality output by color printing is used for pages including color images among the pages that make up the content, while plain paper is used for pages with monochrome images. Uses such as that are also conceivable.

  Printing devices with a job hold function have also appeared. The job hold function is a function that holds a plurality of print jobs temporarily or permanently in a printing apparatus, and selects and prints a desired print job from the held print jobs at a later stage. That is. In addition, when multiple print jobs are selected and the selected print jobs are printed together, subsequent print jobs can be executed simultaneously with the end of the preceding print job. Can save the time required for interaction. For this reason, it is possible to improve the operating rate of the printing apparatus and to improve the productivity at the time of creating printed matter by the printing apparatus.

  Thus, in a printing machine capable of printing using various sheets, it is possible to obtain a complicated printed matter in which various sheets are combined. However, the following cases are conceivable when a plurality of complicated print jobs combining a plurality of types of sheets are further selected and a print instruction is issued. In other words, even if the printing machine has a plurality of paper feed stages, it is assumed that a plurality of types of sheets used by a plurality of selected print jobs are loaded into the paper feed stage at the start of printing. I can't say that. If printing starts when a sheet to be used by a print job is not loaded in any of the paper feed trays, the printer issues an error such as no sheet at the stage of feeding the sheet. The printing process is interrupted. Here, if the user loads a sheet used by the print job into any of the paper feed stages, the printing process can be resumed. However, after the user selects a plurality of print jobs and gives a print instruction collectively, the user may leave the printing apparatus and perform another process, and the print process is interrupted due to the absence of a sheet or the like. It is possible that you will not notice that you are doing. When such a situation occurs, useless down time of the printing apparatus becomes long, which causes trouble for other users.

  In order to prevent such a situation in advance, if the user stands by in the vicinity of the printing apparatus in preparation for a situation where there is no sheet, the printing apparatus will be in a print suspended state for a long time. Can be avoided. However, this is undesirable from the standpoint of productivity of the original printing apparatus and user convenience.

An object of the present invention is to provide a technique for preventing in advance the occurrence of an error due to the fact that a sheet necessary for execution of a print job is not set in a paper feed cassette when a registered print job is selected and executed. The purpose is to do.

In order to achieve the above object, an image processing apparatus according to an aspect of the present invention has the following arrangement. That is,
Each of the plurality of storage units includes a plurality of storage units capable of storing sheets and an image forming unit that forms an image on a sheet conveyed from any one of the plurality of storage units. An image processing apparatus capable of registering sheet type information in association with a copy,
Registration means for registering a print job that can be instructed in association with sheet type information;
Means for displaying a list screen of registered print jobs on the display unit;
The list screen indicates that there is no sheet to be used for the print job based on the fact that the print job associated with the sheet type information that matches the sheet type information associated with the storage unit in the no sheet state is registered. And notifying means for notifying in the above.

According to the present invention, when a registered print job is selected and executed, occurrence of an error without a sheet due to the fact that a sheet necessary for execution of the print job is not set in the paper feed cassette is prevented in advance. be able to.

  The job hold list 702 is an area for displaying a list of print job data saved in the saved document storage area 512 of the digital printing machine 102. In the example of FIG. 7, six print job data are displayed. Note that the digital printer 102 can store more print job data in the HDD 209 than can be displayed in the job hold list 702 at the same time. For example, when seven or more print job data are stored, the user can sequentially display all stored print job data in the job hold list 702 by pressing the scroll buttons 705 and 706. . In the print job data displayed in the job hold list 702, a job name 710, a user name 711, and a date / time field 712 indicating the date and time when the print job is stored in the digital printing machine 102 are displayed. .

  It is assumed that the user who operates this job hold screen selects a job to be printed based on such information.

  Assume that the user operating the job hold screen in the job hold function of the digital printing machine 102 is “Operator A”. Of the plurality of jobs shown in the job hold list 702 in the figure, there are three jobs whose user name is “Operator A”. That is, the jobs “JobA”, “JobD”, and “JobE”.

  Here, there may be a use case in which a user operating the digital printing machine 102 selects and prints a user's print job that does not match the user name of the user. However, in the main use case, the user often selects and prints the user's own print job as a print job to be printed. For the above reason, in the following description, a case where the user selects and prints the user's own print job will be described as an example. However, a case where the user selects a print job that is not the user's own print job and executes printing can also be applied to the present invention.

  Here, when the user presses the part of the print job displayed in the job hold list 702 with a finger or the like, the print job is selected, that is, selected as a print job to be printed. . This print job selection process will be described in detail with reference to the subsequent drawings.

  The print job list 703 is used to display a list of print jobs for which printing processing has been started in the digital printing machine 102. In the example of FIG. 7, there is no print job for which print processing has been started. That is, the printer unit 1000 of the digital printing machine 102 is in an idle state.

  A print start button 708 is a button for instructing start of print processing of the print job selected in the job hold list 702. A cancel button 709 is a button for canceling execution of a print job in a state in which print processing has been started by the print start button 708.

  A mismatch check button 704 is a button for instructing collation processing between sheet information used by the print job selected in the hold job list 702 and sheets loaded in the digital printing machine 102. The collation process referred to here checks whether or not a sheet used by a print job stored in the HDD 209 is not loaded in any of the paper feeding units included in the digital printing machine 102. That is, for example, it is assumed that the print job 1 is set to use only “sheet A”. Then, it is assumed that “sheet A” is set in any of the paper feeding units provided in the digital printing machine 102 and the “sheet A” is loaded (case 1). When the mismatch check button 704 is pressed in this state, it is determined that “sheet A” scheduled to be used by the print job 1 is available as a result of the collation.

  As another example, when print job 1 is set to use only “sheet A”, “sheet A” is set in one of the paper feed units included in digital printing machine 102. Assume that the remaining amount of “sheet A” in the sheet feeding unit is zero (case 2). When the mismatch check button 704 is pressed in this state, “sheet A” scheduled to be used by the selected print job is prepared to be usable as a result of collation, but the remaining amount of “sheet A” is prepared. It can be seen that there is no state. As an avoidance method in this case, the user may replenish “sheet A” to the sheet feeding unit.

  Still another case is assumed. Assume that the selected print job 1 uses only “sheet A”. Then, it is assumed that “sheet A” is not set in any of the paper feeding units included in the digital printing machine 102 (case 3). When the mismatch check button 704 is pressed in this state, it is understood that “sheet A” scheduled to be used by the selected print job is not available as a result of collation. As an avoidance method in this case, it means that the user must set “sheet A” as setting information in any of the sheet feeding units and supply “sheet A” to the sheet feeding unit.

  In the case 2 and case 3 described above, if the user presses the print start button 708 with a print job selected, an unprepared sheet will be fed and a paper out error will occur at that stage. The printing process stops. That is, the productivity in the digital printing machine 102 is reduced.

  On the other hand, in the first embodiment, the function provided by the mismatch check button 704 determines whether or not the sheet used in the selected print job can be used in the digital printing machine 102 before the print start button 708 is pressed. User can confirm. This is because the printing process can be started after setting or replenishing the sheet based on the inspection result by the mismatch inspection button 704. This allows the user to prepare the sheet before the start of the print job, so after starting the execution of the print job, a paper out error occurs and the printing process by the digital printing machine is interrupted, resulting in increased productivity. Can reduce the risk of incurring a decline.

  A detail / change button 707 is a button for confirming the details of the print job selected in the job hold list 702 or for changing to a screen for changing the print specifications.

  FIG. 8 is a diagram illustrating an example of a sheet management table for managing information on sheets loaded in each sheet feeding unit in the digital printing machine 102 according to the first embodiment. This sheet management table is stored in the HDD 209 and is referred to by the CPU 212.

  In the example illustrated in FIG. 8, for each of the ten sheet feeding units included in the digital printing machine 102, information on the size 812, the sheet type 813, and the remaining amount 814 is managed using the sheet feeding unit ID 811 as a key. .

  For example, 801 indicates that the size of the sheet loaded in the sheet feeding unit (ID = 1) is A4, the sheet type is plain paper 1, and the remaining amount is 3. The numerical value indicated by the remaining amount 814 has the following meaning. 3: Full (100%), 2: Small remaining amount (25%), 1: Very small remaining amount (less than 5%), 0: No remaining amount (0%). The accuracy of detecting the remaining amount of the sheet can be made finer by increasing the accuracy of the remaining amount sensor. However, the digital printing machine 102 according to the first embodiment detects the remaining amount of the specifications as described above.

  FIG. 9 is a diagram for explaining sheet information used by each job of JobA, JobD, and JobE shown in FIG.

  When the job hold function program 511 in FIG. 5 stores the print job data in the saved document storage area 512, the information shown here is held by storing the print settings at the same time. Note that the sheet information used by the print job is included in the print settings.

  FIG. 9A shows a total of two types of sheets: JobA is a sheet with a size of A4 and the sheet type is “plain paper 1”, and a sheet with a size of A4 and the sheet type is “double-sided coated paper 1”. Indicates use. FIG. 9B shows a total of two types of sheets: JobD is a sheet whose size is LTR and the sheet type is “plain paper 1”, and a sheet whose size is 11 × 17 and whose sheet type is “plain paper 1”. Indicates use. Similarly, FIG. 9C shows a sheet with JobE having a size of A4 and a sheet type of “plain paper 1”, a sheet having a size of A4 and a sheet type of colored paper (red), and a sheet having a size of A3. It shows that three types of sheets having a type of “double-side coated paper 2” are used.

  FIG. 10 is a diagram illustrating an example of a job hold function operation screen displayed on the operation unit 204 in the digital printing machine 102 according to the first embodiment. Here, a display example is shown 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. Parts common to those in FIG. 7 are denoted by the same symbols. Here, the operator A sequentially selects JobA, JobD, and JobE, and three jobs are selected. The selected job is indicated by a selection mark (1001, 1002, 1003) on the left of the job name field, and a numerical value indicating the selected order is given. Reference numeral 1004 denotes JobE selected last, and is highlighted. This indicates that the job hold list 702 is currently selected. That is, when the detail / change button 707 is pressed in this state, it is possible to check the detailed information of JobE and change the setting.

  FIG. 11 is a diagram illustrating an example of a job hold function operation screen displayed on the operation unit 204 in the digital printing machine 102 according to the first embodiment. Here, an example of a screen displayed immediately after the mismatch check button 704 is pressed in the job hold list 702 in the state shown in FIG. Portions common to those in FIG. 10 are denoted by the same symbols, and description thereof is omitted.

  In FIG. 10, for each of the three jobs (JobA, JobD, JobE) selected by the user, the consistency between the sheet that each print job is scheduled to use and the sheet set in the paper feed unit of the digital printing machine 102 is checked. doing.

  In Job A, the sheets scheduled to be used by the print job are set in the sheet feeding unit as shown in FIGS. 8 and 9, and the remaining amount of sheets is not zero. Therefore, in this case, when the user presses the print start button 708, the user can know that the possibility that no paper will occur is extremely low before instructing the start of printing.

  As for JobD, the sheets scheduled to be used by the print job are set in the sheet feeding unit as shown in FIGS. 8 and 9, but there are sheets in which the remaining amount of sheets is zero. Specifically, the remaining amount of the sheet of the size “11 × 17” and the sheet type “plain paper 1” set in the “paper feeder 9” is zero. Accordingly, when the print start button 708 is pressed in this state, a paper out error occurs at the stage of trying to feed a sheet of size “11 × 17” and the printing process is stopped. This is indicated by a warning mark 1101. The user who recognizes that the mark 1101 has been displayed may perform an appropriate treatment, that is, replenish the sheet feeding unit 9 with a sheet of size “11 × 17” and sheet type “plain paper 1”.

  In the case of JobE, as shown in FIGS. 8 and 9, there are sheets that are not set in any of the paper feeding units, as shown in FIGS. 8 and 9. Specifically, a sheet of size A3 and sheet type “double-sided coated paper 2” is not set in any paper feeding unit. This is indicated by a warning mark 1102. Therefore, if the user presses the print start button 708 in this state, the user will be notified that a print job will be stopped due to an out-of-paper error at the stage of trying to feed the sheet. I can know. The user who has confirmed that the mark 1102 has been displayed identifies an appropriate action, that is, another sheet feeding unit (preferably a sheet feeding unit that has not been determined to be used in a job) and supplies the sheet. The sheet setting of the paper section is changed to size A3 and the sheet type is “double-sided coated paper 2”. Further, the user supplies the corresponding sheet to the sheet feeding unit. If there is an original sheet, the user may replace the sheet with a corresponding sheet. The warning mark 1101 indicates that the sheet used by the print job is set in the paper feeding unit, but the remaining amount is zero. The warning mark 1102 indicates which paper feeding unit uses the sheet used by the print job. Is also not set. By changing the shape of the warning mark 1101 and the warning mark 1102, the user can determine whether the job sheet is set in any of the paper feeding units, or the job sheet is set but the remaining amount is zero. Can be distinguished and recognized.

  As described above, when the mismatch check button 704 is pressed, the marks 1101 and 1102 are displayed in association with print jobs that are likely to run out of paper, thereby preventing the user from stopping the print job. It becomes possible to make it.

  When the user presses the details / change button 707 in the state of FIG. 11, the sheet size and sheet type (for example, FIG. 9C) used by the selected JobE are displayed. Here, the sheet information that is not set in any paper feed unit (here, A3, double-sided coated paper) is displayed in reverse, for example, so that it is not set in any paper feed unit by the user. A sheet can be presented.

  In the state of FIG. 11, when the user selects JobD and presses the details / change button 707, the sheet size and sheet type (for example, FIG. 9B) 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 feeding unit in which the sheet is set. As a result, the user can grasp the sheet information of the sheet size and sheet type used by JobD and the remaining amount is zero, and the sheet feeding unit. As described above, when displaying the sheet size and the sheet type, how to display the sheet information when the sheet is not set in any of the sheet feeding units and the sheet information with the remaining sheet amount of zero. Change the way you go. Accordingly, the user can distinguish and know whether the displayed sheet of the size and type is not set in any sheet feeding unit or the remaining amount of the sheet is zero.

  FIG. 12 is a diagram illustrating an example of a sheet management table for managing information on sheets loaded in each sheet feeding unit in the digital printing machine 102 according to the first embodiment. Based on the screen and operation in FIG. The sheet management table after a user performed avoidance processing is shown. The sheet management table in FIG. 12 is also stored in the HDD 209 and is referred to by the CPU 212.

  The difference from the table shown in FIG. 8 is that the sheet type of the sheet feeding unit (ID = 4) is changed to “double-side coated paper 2” and the sheet is replenished (remaining amount is 3). Another difference is that the sheet of the paper feed unit (ID = 9) has been replenished and the remaining value has changed from 0 to 3.

  In this way, when the user presses the mismatch check button 704 in FIG. 11 again with the sheet registration and replenishment processing performed so as to be in the state shown in FIG. 12, the screen returns to the screen shown in FIG. That is, it can be seen that the warning marks 1101 and 1102 indicating the cause of the absence of paper are erased.

  When the user presses the print start button 708 in this state, the user can know before the start of printing that the possibility that no paper will occur after the digital printing machine 102 starts the printing process is extremely low. Therefore, the labor productivity of the user can be improved and the operating rate of the digital printing machine 102 can be increased. As a result, it is possible to improve the convenience of the digital printer 102 compatible with the POD market.

  FIG. 13 is a flowchart for explaining processing by the digital printing machine 102 according to the first embodiment. This process is achieved by the CPU 212 of the controller unit 205 executing a program that is read from the ROM 207 or the HDD 209 and loaded in the RAM 208. This process starts when the screen shown in FIG. 7 is displayed on the display unit of the operation unit 204.

  First, in step S <b> 1301, the CPU 212 enters a user operation waiting state on the screen illustrated in FIG. 7 displayed on the operation unit 204. Here, it stays in this S1301 until some operation is performed by the user. If the user performs any operation on the operation unit 204, the process advances to step S1302, and the CPU 212 determines whether the operation is an operation for selecting a print job displayed in the job hold list 702. If it is determined that the operation is to select a print job displayed in the job hold list 702, the process advances to step S1303, and the CPU 212 determines whether the selected print job is already selected. If it is determined that the print job is already selected, the process advances to step S1304, and the CPU 212 cancels the print job selection state and returns to step S1301. On the other hand, if it is determined in step S1303 that the selected print job is not already selected, the process advances to step S1305, and the CPU 212 sets the print job to a selected state. Specifically, as shown in FIG. 10, the CPU 212 displays the selected print job with marks (1001, 1002, 1003) indicating the selected state, and returns to S1301.

  On the other hand, if it is determined in step S1302 that the operation in step S1301 is not an operation for selecting a print job displayed in the job hold list 702, the process advances to step S1306. In step S1306, the CPU 212 determines whether the mismatch check button 704 has been pressed. If it is determined that the mismatch check button 704 has been pressed, the process advances to step S1307, and the CPU 212 performs a mismatch check process and advances to step S1301. The processing in S1307 will be described later with reference to the flowchart in FIG.

  If it is determined in step S1306 that the mismatch check button 704 has not been pressed, the process advances to step S1308, and the CPU 212 determines whether the operation in step S1301 is a pressing process for the print start 708 button. If the print start 708 button is pressed, the process advances to step S1309, and the CPU 212 executes print processing for the selected print job. When print processing for all selected print jobs is completed, the process returns to step S1301. On the other hand, if the print start 708 button is not pressed in S1308, the CPU 212 advances the process to S1310 because the operation in S1301 does not correspond to any of the above processes. In step S1310, the CPU 212 executes a process corresponding to the operation, and when the process ends, the process returns to step S1301. Note that the details of the processing of S1310 are not important for describing the effect of the present embodiment, and thus the description thereof is omitted.

  FIG. 14 is a flowchart illustrating details of the mismatch check process (S1307) when the mismatch check button 704 according to the first embodiment is pressed. This process is achieved by the CPU 212 of the controller unit 205 executing a program that is read from the ROM 207 or the HDD 209 and loaded in the RAM 208.

  First, in step S <b> 1401, the CPU 212 acquires the sheet type and sheet remaining amount information set in each sheet feeding unit included in the digital printing machine 102. The processing of S1401 is performed by the CPU 212 instructing the sheet management unit 211 and referring to, for example, a sheet management table as shown in FIG. In step S1402, it is determined whether the mismatch check process has been completed for all print jobs. If the mismatch check process has been completed for all print jobs, the process ends. If not, the process ends. The process proceeds to S1403. In step S1403, the CPU 212 determines the next print job to be subjected to the mismatch check process. In step S1404, the CPU 212 obtains information on sheets used by the print job as illustrated in FIG. 9 for the print job determined in step S1403. In step S1405, the CPU 212 initializes two types of flags (Flag1 and Flag2) for holding the mismatch check result. When Flag1 is true, it indicates a mismatch state, that is, the print job designates a sheet that is not set in any paper feed unit. When Flag2 is true, it indicates that the print job is set to the sheet feeding unit but designates a sheet whose remaining amount is zero. Note that these two flags are set in the RAM 208.

  In step S1406, the CPU 212 determines whether or not the check processing has been completed for all the sheets extracted in step S1404 and used by the print job in the print job determined in step S1403. If the determination result in S1406 is false, that is, if all the sheets have not been checked, the process proceeds to S1407, and the CPU 212 selects the next sheet to be checked among all the sheets that the print job intends to use. decide. The process advances to step S1408, and the CPU 212 checks whether or not the checks for all paper feed units have been completed. If not, the process advances to step S1409 to determine the next paper feed unit. On the other hand, if the checks for all the paper feeding units have been completed, the process advances to step S1406 to perform the next sheet comparison process.

  If the determination result in S1408 is false, since there is a sheet feeding unit that has not been compared yet, the process proceeds to S1409, and the CPU 212 determines the next sheet feeding unit to be compared, and proceeds to S1410. . In step S1410, the CPU 212 determines whether the sheet determined in step S1407 matches the sheet size and sheet type set in the sheet feeding unit determined in step S1409. If they do not match, the process returns to S1408 to execute the next paper feed unit check process.

  On the other hand, if it is determined in step S1410 that the determined sheet matches the sheet size and sheet type set in the determined sheet feeding unit, the process advances to step S1411, and the CPU 212 sets the value of Flag1 to “false”. To "". In step S <b> 1412, the CPU 212 checks the remaining amount of sheets in the sheet feeding unit determined in step S <b> 1409. If it is determined that there is a remaining sheet, the process advances to step S1413, and the CPU 212 sets the value of Flag2 to “false” and returns to step S1408. On the other hand, if the determination result in S1412 is false, the process returns to S1408.

  If the result of the determination in S1406 is true, that is, all the sheets used by the determined print job have been checked for mismatch with the sheets of all the paper feed units of this digital printing machine 102 and the presence or absence of sheets. The process proceeds to S1414. In step S1414, the CPU 212 determines whether the value of the flag Flag1 is “true”. If the value of the flag Flag1 is “true”, it means that any sheet used by the print job determined in S1403 is not set in any paper feed unit of the digital printing machine 102. Means. Accordingly, in this case, the process proceeds to S1415. For example, as shown in FIG. 11, a warning mark 1102 indicating a mismatch state is displayed in the column of the print job in the job hold list 702, and the process proceeds to S1402. On the other hand, if the result of the determination in S1414 is false, the process proceeds to S1416 to determine whether the value of the flag Flag2 is “true”. That is, it is determined whether any sheet used by the print job selected in S1403 is set in any sheet feeding unit included in the digital printing machine 102, and whether or not the remaining amount of the sheet is zero. Determine. If the determination result is true, the process advances to step S1417, and the CPU 212 displays a warning mark 1101 indicating the absence of sheet in the column of the print job in the job hold list 702, for example, as shown in FIG. . If the determination result in S1416 is false, the process proceeds to S1402.

  The above is the detailed description of the mismatch check process of S1307 in FIG.

As described above, according to the first embodiment, the sheet used by the print job is set in the paper feeding unit before executing the print processing of the print job stored in the digital printing machine 102 by the job hold function. Can be determined. Further, it is possible to determine whether or not the sheet is present in the sheet feeding unit before starting the printing process. At this time, whether the sheet used by the selected print job is set in the paper feed unit, whether the sheet is set in the paper feed unit, and the sheet actually exists. It can also be determined whether or not. [Embodiment 2]
In the above-described first embodiment, as shown in FIG. 11, an example in the case of a specification that displays one of the warning marks 1101 and 1102 has been shown. However, although the sheet is set in the sheet feeding unit, the state where the remaining amount is zero and the state where the sheet used by the print job is not set in any sheet feeding unit can occur at the same time. For example, assuming that the print job is to use a plurality of sheets, it is assumed that the selected print job specifies sheet A and sheet B.

  Here, the sheet A is set in the sheet feeding unit, but its remaining amount is zero. Further, it is assumed that the sheet B is not set in any sheet feeding unit. In this case, the sheet A corresponds to the condition for displaying the warning mark 1101 shown in FIG. 11, and the sheet B corresponds to the condition for displaying the warning mark 1102. In the example of FIG. It cannot be confirmed that there is no sheet remaining in the part.

  FIG. 15 is a diagram illustrating an example of a job hold function operation screen displayed on the operation unit 204 in the digital printing machine 102 according to the second embodiment of the present invention. In addition, the part which is common in above-mentioned FIG. 7 is shown with the same symbol. Note that FIG. 15 shows the screen after the mismatch check button 704 is pressed, but the other behaviors and components of the screen are the same as those in the first embodiment, so a detailed description thereof will be given. Omitted. In addition, the hardware configuration of the digital printing machine 102 according to the second embodiment is the same as that of the first embodiment, and a description thereof will be omitted.

  As shown in the drawing, both warning marks 1503 and 1504 are displayed in the JobD portion. As a result, for a plurality of sheets, the user sets the sheet to the sheet feeding unit but has a remaining amount of zero, the sheet is not set to any sheet feeding unit, and the sheet However, it can be confirmed that none of the paper feed units is present.

  In FIG. 15, for example, when the detail / change button 707 is pressed while JobD is selected, the sheet size and sheet type (for example, FIG. 9B) used by JobD are displayed. Here, a sheet having a remaining amount of zero is displayed so as to be identifiable, and the display of the sheet feeding unit in which the sheet is set blinks. In addition, the sheet type that is not set in any of the paper feeding units is displayed in reverse video. This makes it possible to present to the user the sheet size and sheet type used by JobD, the remaining sheet of zero, the sheet feeding unit, and the sheet type that is not set in any sheet feeding unit.

  FIG. 16 is a flowchart illustrating details of the mismatch check process (S1307) when the mismatch check button 704 according to the second embodiment is pressed. In addition, the part which is common in FIG. 14 which concerns on above-mentioned Embodiment 1 is shown with the same symbol. This process is realized by the CPU 212 of the controller unit 205 executing a program that is read from the ROM 207 or the HDD 209 and loaded in the RAM 208.

  The difference from FIG. 14 is that in FIG. 14, the process transits to S1402 after the mismatch icon is displayed in S1415. On the other hand, in FIG. 16, after transitioning to S1416 after S1415, the mismatch icon (1503 in FIG. 15) is displayed, and then the no-sheet icon (1504 in FIG. 15) is displayed when there is no sheet. Transition to the process for

As a result, as shown in FIG. 15, for one print job, a warning mark 1503 indicating that there is no sheet setting for any sheet feeding unit, and a sheet corresponding to any sheet feeding unit are displayed. A warning mark 1504 indicating the absence can be displayed at the same time.
[Embodiment 3]
In FIG. 7 according to the first embodiment, when the mismatch check button 704 is pressed, only the print job selected in the job hold list 702 is checked when the button 704 is pressed. It was.

  Here, as shown in FIG. 11, it is assumed that the print job is made non-selected after the warning marks 1101 and 1102 are displayed by pressing the mismatch check button 704. An embodiment in which the display state of the warning mark 1101 or the warning mark 1102 is maintained even after such an operation is performed is conceivable.

  The user performs various operations using the operation screen of the job hold function as shown in FIG. 7, and it is highly assumed that various trial and error operations are naturally performed in the process. That is, an operation is such that a print job that has been selected once is deselected, and the print job is selected again at a later timing. Considering the convenience at the time of the user's operation, even if the print job is in the non-selected state, the print job selected by the user and subjected to the mismatch check is selected again at a later timing. Corresponds to a print job candidate. In consideration of such a situation, it is not always a good idea to reset the display of the warning marks 1101 and 1102 when the selected print job is set to the non-selected state. It may be preferable to maintain

Therefore, in the third embodiment, as shown in FIG. 17, even when the selected print job (JobD) is changed to the non-selected state, warning marks 1503 and 1504 displaying the mismatch inspection result are displayed. Keep the display state.
[Embodiment 4]
After the mismatch check button 704 is pressed, a warning mark 1101 or a warning mark 1102 is displayed for each of the jobs displayed in the hold job list 702 in FIG. 11 and equivalent drawings. After these marks are displayed, the mismatch check button 704 is pressed again, and the display state is maintained until updated.

  By storing this display state together with print job data and print settings stored in the saved document storage area 512 in a non-volatile manner, a further effect can be obtained. That is, the mismatch check result can be stored in a permanent form. As a result, for example, even when the power of the digital printing machine 102 is turned off and the power is turned on again, the result of the mismatch inspection performed before turning off the power can be held at the next power on. is there. As a result, when the power is turned on, the result of the mismatch inspection performed before the power is turned off can be displayed in the hold job list 702 without pressing the mismatch inspection button 704 again.

  As a result, for example, even if the user turns off the digital printing machine to interrupt the work in the middle of the work and turns on the power to resume the work, the work can be continued easily. Can be confirmed.

  In FIG. 19, 1900 is a controller, 1901 is a CPU, 1902 is a RAM, 1903 is a program ROM, and 1904 is a data ROM. The CPU 1901 controls the operation of the printing apparatus 1800 based on a program stored in the program ROM 1903. The RAM 1902 is used as a main memory when the CPU 1901 operates and an area (work area) for temporarily storing information. The data ROM 1904 stores fixed information such as fonts that are called when the CPU 1901 executes the program. A network interface (I / F) 1905 is connected to the network 1804 and receives a job from the host computer. A printer interface (I / F) 1906 connects the printer engine 1908 and the controller 1900. The external storage device 1907 is a large-capacity storage device such as a hard disk or a flash memory. The CPU 1901, RAM 1902, ROM 1903, 1904, interfaces 1905, 1906, external storage device 1907, and UI (user interface) 1909 are connected via a system bus 1910. The UI 1909 includes an operation panel including a touch panel, hard keys, a display unit, and the like that accept operations performed by the user.

  FIG. 20 is a block diagram illustrating a software configuration of the controller 1900 of the printing apparatus 1800 according to the fifth embodiment and its peripheral configuration.

  The UI control unit 2001 connects the UI 1909 and the job control unit 2004. A network control unit 2002 controls the network interface 1905. The document management unit 2003 stores the job. A job control unit 2004 controls job execution by the controller 1900. An image processing unit 2005 expands the input job and generates image data for printing. A printer control unit 2006 controls the printer engine 1908 via the printer interface 1906. The setting storage unit 2007 stores various setting information set from the UI 1909, and paper settings are also stored here. Reference numerals 2010 to 2014 denote sheet feed stages mounted on the printer engine 1908, and here, five sheet feed stages are mounted.

  With the above configuration, a hold job submitted from the outside is temporarily stored in the external storage device 1907 (FIG. 19) and managed by the document management unit 202003. Note that the control processing and management processing of the parts indicated by the above-mentioned 2001 to 2007 are realized by the CPU 1901 executing the program in the program ROM 1903.

  FIG. 21 is a diagram illustrating an example of a hold job list displayed on the UI 1909 of the printing apparatus according to the fifth embodiment.

  Reference numeral 2101 denotes a list of hold jobs held in the external storage device 1907, in which a predetermined number of held jobs are displayed. In the job list 2101, there are two states where a job is selected. That is, there are a current selection state selected as an operation target for one job and a multiple selection state selected as a correspondence of operations for a plurality of jobs. The currently selected job is always included in the multiple selection job.

  Reference numeral 2102 denotes a currently selected job, which is represented by a colored background of the job display. Three jobs indicated by reference numerals 2102 to 2103 indicate a plurality of selected hold jobs, and the selected order is expressed by numbering. In FIG. 21, job1 (job 1) to job3 (job 3) are selected in this order. Reference numeral 2104 denotes an update button, and 2105 denotes an icon indicating that the job is a media mismatch. When the update button 2104 is pressed, the mismatch icon 2105 is updated to the latest state. The update button 2104 is grayed out and cannot be pressed when there are no plurality of selected jobs. A paper replacement button 2106 is a transition button to a paper replacement screen for performing paper replacement (switching the paper feed destination) for the current selected job. A print button 2107 is a button for instructing printing to execute and print a plurality of selected hold jobs in the order of selection. The paper substitute button 2106 is grayed out and cannot be pressed if there is no current selection job. When there are a number of hold jobs that do not fit in the job list 2101, other hold jobs that are not currently displayed can be displayed by pressing the scroll button 2108.

  In FIG. 21, a media mismatch has occurred in job 1. That is, when job 1 requests the paper size and paper type set in each paper feed stage to be used, the paper size and paper type actually set in each paper feed stage are It is identifiable that it is different from the request. In this case, when job 1 is selected as shown in FIG. 21 and sheet substitute button 2106 is pressed, the screen transitions to the screen shown in FIG.

  FIG. 22 is a diagram illustrating an example of a sheet replacement screen displayed on the UI 1909 of the printing apparatus 1800 according to the fifth embodiment. This screen is displayed by pressing the paper substitute button 2106 while the current selection job (for example, job 1) is selected as shown in the screen of FIG.

  Reference numeral 2201 denotes a paper list used by the current selected job (job 1). [] Shown at the left end of the list indicates a paper feed stage. For example, 2202 requests the paper feed stage 1 to request the paper size A4 and the media type (Plain (plain paper)). Is displayed. Further, no substitute paper for the paper in the paper feed stage 1 is set, and no media mismatch occurs. That is, it is indicated that the paper of the size and type requested by the job 1 is set in the paper feed stage 1.

  Reference numeral 2203 denotes the currently selected paper feed stage, and the background color is added to indicate that the paper feed stage is being selected. In 2203, this job 1 requests the paper size A3 and the media type (Heavy) for the paper feed stage 3, but the paper set in the paper feed stage 3 does not satisfy the conditions. . That is, the paper feed stage 3 is in a state of no paper. Therefore, by changing the paper feed destination to the paper feed stage 4, it is set so that paper of the size and type requested by the job 1 can be fed. An icon 2204 indicates that a media mismatch has occurred in the paper feed stage 3. That is, this job 1 requests the paper size A3 and the media type (Heavy (thick paper)) from the paper feed stage 3, but the paper feed stage 3 does not have a sheet that meets the conditions. A media mismatch has occurred. Instead of the paper feed stage 3, a paper feed stage 4 that contains paper of the paper size and type required by the job 1 is designated.

  A “change paper selection” button 2205 is a button for transitioning to a screen for selecting an alternative paper. The “to paper destination before change” button 2206 is a button for canceling the substitution setting for each paper. An OK button 2207 is a button for confirming the selected substitute sheet. A cancel button 2208 is a button for canceling the substitute sheet temporarily set on this screen.

  FIG. 23 is a flowchart for describing processing in which the controller 1900 of the printing apparatus 1800 according to the fifth embodiment displays a job list screen. A program for executing this processing is stored in the program ROM 1903, and this processing is achieved by the CPU 1901 executing the program.

  This process is started when an event instructing display of the job list screen is issued. First, in step S601, for example, as shown in FIG. 21, a list of hold jobs managed and stored by the document management unit 2003 is displayed in a predetermined order. Here, the hold job is a job that has been printed or is an unprinted job and saved in the external storage device 1907. When the job list screen is displayed for the first time or when switched from another function and displayed, the CPU 1901 sets “none” for both the current selection job and the multiple selection job in step S602. In step S <b> 603, the CPU 1901 waits for a user input operation using the UI 1909.

  If there is any input in S603, the process proceeds to S604, and the CPU 1901 determines what the input is. If the input is, for example, the user's finger touches a job in the job list 2101, that is, if a job selection instruction is given, the process advances to step S <b> 605, and the CPU 1901 determines that the job (currently selected job) ) Or not. Otherwise, the process proceeds to S606, where the selected job is set as the current selected job, and the job is displayed with a background color, for example, as indicated by 2102 in FIG. In step S607, the CPU 1901 determines whether the job is already a target for multiple selection. If the job is not a target for multiple selection, the process proceeds to step S608, and assigns a selection order number in addition to one of the multiple selection jobs. The job list 2101 is displayed again. The process advances to step S603 to wait for the next input from the UI 1909. If it is determined in step S607 that the job has already been selected, a selection order number is not processed, and the process advances to step S603.

  On the other hand, if it is determined in S605 that the job is already the current selection job, the processing proceeds to S609, where the CPU 1901 determines that the selected job is an instruction to remove the selected job from the current selection job, and displays the job without the background color. In step S610, since the job is also included in a plurality of selection targets, the CPU 1901 removes the job from the selection target, reassigns the selection order number to each job, and displays the job list 2101 again. The process advances to step S603 to wait for the next input from the UI 1909.

  If it is determined in step S604 that the update button 2104 has been pressed while there is a selected job, the process advances to step S611, and the CPU 1901 updates the media mismatch state for a plurality of selected jobs, and obtains the result. Displayed on the job list 2101. The process advances to step S603 to wait for the next input from the UI 1909. The processing of S611 will be described later with reference to the flowchart of FIG.

  If another button is operated in S604, the process proceeds to S612. In S612, it is determined whether or not the paper substitute button 2106 has been pressed. If the paper substitute button 2106 has not been pressed, the process proceeds to S615, and processing corresponding to the pressed button is performed, and the process proceeds to S603. If it is determined in step S612 that other buttons, such as the print button 2107, have been pressed, the respective processes such as printing a plurality of selected jobs in the order of selection are performed. To do.

  On the other hand, if it is determined in step S612 that the paper substitute button 2106 has been pressed, the process advances to step S613, and the CPU 201 displays, for example, paper information for displaying a paper substitute screen as shown in FIG. 22 for the currently selected job. Execute display processing. In step S614, the media mismatch status of the job is updated, and the job list 2101 is displayed again. The above processing is continuously executed until the job list screen is switched to another screen. Note that the processing of S613 will be described later with reference to the flowchart of FIG.

  According to this processing, a list of hold jobs can be displayed on the UI 1909, and the user can select a desired job from the job list display and print it. At that time, it is also possible to easily check whether the size and type of paper used for printing by the selected job matches the size and type of paper set in the paper feed tray. If the size and type of paper used for printing by the selected job does not match the size and type of paper set in the paper feed tray, the paper of the size and type used for the job is stored. It is possible to execute another job by designating another paper source.

  FIG. 24 is a flowchart for describing processing for determining a media mismatch state of a plurality of selected jobs by the controller 1900 of the printing apparatus 1800 according to the fifth embodiment. A program for executing this processing is stored in the program ROM 1903, and this processing is achieved by the CPU 1901 executing the program. This process corresponds to the details of the process of S611 in FIG.

  First, in step S701, the CPU 1901 determines whether there is a job for which the media mismatch state has not been determined among the information on the plurality of selected jobs. If processing for all the selected jobs has been completed, the processing proceeds to step S709. Proceed to In step S <b> 709, the CPU 1901 acquires the determination result of the media mismatch state of the selected job, and ends this process.

  On the other hand, in S701, if there is a job that has not yet been subjected to the media mismatch status determination process, the process advances to S702 to determine whether the job is a target of media mismatch determination. If it is determined that the job is not a target job, the process advances to step S701 to perform processing for the next job. If it is determined in step S702 that the job is a target of media mismatch determination, the process advances to step S703, and the CPU 1901 determines whether information on a sheet to be used in the job has been acquired. If it is determined that the job has not been acquired, the process advances to step S704, and the information on the paper used by the job is acquired and stored with the three attributes of the paper feed stage, size, and media type (paper type), and the process advances to step S705. Here, when different sheets of one job use paper of the same paper feed stage, paper size, and media type, they are grouped as the same. If it is determined in step S703 that the information on the sheet to be used in the job has been acquired, the process advances to step S705.

  In step S <b> 705, the CPU 1901 determines whether determination processing has been completed for all paper feed stages used in the job. When the determination process is completed for all the paper feed stages, the process advances to step S708, and the CPU 1901 selects the next job among the selected jobs, and advances to step S701.

  On the other hand, if it is determined in step S705 that the determination process has not been completed for all the paper feed stages used in the job, the process advances to step S706, and the CPU 1901 determines the obtained paper feed stage information in the paper feed stage. Determine if there is a media mismatch and save the result. The process advances to step S707, and the process advances to step S705 with the next paper feed stage as a determination target. In this way, when the processing of all the selected jobs is completed in S701, the stored determination results of each job are acquired, and this processing is ended.

  As a result, in the selected job, does the paper size and paper type of the paper feed tray requested by the job match the paper size and paper type actually set in the paper feed tray? Can be determined. When multiple jobs are selected, in each of the multiple jobs, the paper size and paper type of the paper source requested by the job, and the paper size actually set in that paper source It can be determined whether the paper type matches.

  FIG. 25 is a flowchart for describing processing in which the controller 1900 of the printing apparatus 1800 according to the fifth embodiment displays a paper substitute screen. A program for executing this processing is stored in the program ROM 1903, and this processing is achieved by the CPU 1901 executing the program. This process corresponds to the details of the sheet replacement screen display process of S613 in FIG.

  First, in step S <b> 801, when the CPU 1901 determines that there is no current selection job or a job that is not a paper replacement target, this processing ends without performing the paper replacement screen display processing. Otherwise, the process advances to step S802, and the CPU 1901 determines whether or not the paper information used for the job has been acquired. If the paper information has been acquired, the process advances to step S804. If the paper information has not been acquired, the process advances to step S803, and as in step S704 in FIG. Acquire and save with three attributes. Then, the process proceeds to S804.

  In step S804, the CPU 1901 determines whether the media mismatch determination process for all sheets used in the job has been completed. If the determination process for all sheets has been completed, the process proceeds to step S807. If not, the process proceeds to step S805. Proceed to In step S805, the CPU 1901 determines a media mismatch for each sheet. In step S806, if a substitute sheet has already been set, information on the substitute sheet and the media mismatch status on the sheet are displayed, and the process advances to step S804. Note that the processing of S805 will be described later with reference to the flowchart of FIG.

  In step S807, the CPU 1901 displays a list of sheet information used in the job as shown in FIG. 22 in a state where no sheet is selected. The process advances to step S808 to wait for input from the UI 1909. If there is an input from the UI 1909, the process advances to step S809, and the CPU 1901 determines the input. If the CPU 1901 determines in step S809 that the instruction is for selecting a sheet, the process advances to step S810, and the CPU 1901 determines whether the sheet is not selected. If it is determined that it has not been selected, the process advances to step S811 to display the selected paper with a background color and advances to step S808. On the other hand, if it is determined that it has already been selected, the process advances from S810 to S812, and the CPU 1901 removes the selected paper from the selected paper, displays it without the background color, and advances to S808. These processes in S809 to S812 are processes for switching the selection / non-selection of paper information.

  On the other hand, if it is determined in step S809 that the “paper change selection” button 2205 for selecting changed paper is pressed, the process advances to step S814 via step S813. In step S814, the CPU 1901 temporarily sets the sheet selected on the change sheet selection screen as an alternative sheet, and the process advances to step S816. If the “to paper before change” button 506 is pressed in S809, the process advances to S815 via S813. In step S815, the CPU 1901 deletes the alternative sheet if the selected sheet is set, and proceeds to step S816. In step S816, the CPU 1901 determines a media mismatch for the selected paper. In step S817, the display of the icon 2204 indicating the mismatch status of the selected paper is updated, and the flow returns to step S808. Note that the processing of S816 will be described later with reference to the flowchart of FIG.

  If it is determined in step S808 that the OK button 2207 or the cancel button 2208 is pressed, the process advances to step S818. In the case of the OK button 2207, the process advances to step S819, and the CPU 1901 determines and saves the substitute sheet information set on this screen as an actual one instead of a temporary one, and ends the processing. On the other hand, in the case of the cancel button 2208, the process advances to step S820 to discard the substitute sheet and the deletion instruction set on this screen, validate the original substitute sheet information, and end the process.

  FIG. 26 is a flowchart illustrating processing in which the controller 1900 of the printing apparatus 1800 according to the fifth embodiment determines the presence / absence of a media mismatch for each sheet. A program for executing this processing is stored in the program ROM 1903, and this processing is achieved by the CPU 1901 executing the program. This process corresponds to the details of the processes in S706 of FIG. 24 and S805 and S816 of FIG.

  First, in step S <b> 901, the CPU 1901 obtains, from the printer engine 1908, paper information set for each paper feed stage of the printer engine 1908. This paper information is stored in the controller 1900 as well as the printer engine 1908. In this case, the information is obtained from the setting storage unit 2007. In step S902, the CPU 1901 determines whether a substitute sheet is set for the sheet obtained from the job. If an alternative sheet is set here, the process advances to step S903, and the CPU 1901 advances to step S905 with the alternative sheet as a determination target. On the other hand, if a substitute sheet is not set, the process advances to step S904, and the CPU 1901 advances to step S905 with the sheet itself as a determination target.

  In step S <b> 905, the CPU 1901 determines whether the information about the paper feed stage, size, and media type of the target paper matches all the paper information of the printer acquired in step S <b> 901. If they match, the process proceeds to S906, and the CPU 1901 determines that there is no media mismatch and proceeds to S908. On the other hand, if they do not match, the process proceeds to S907, and the CPU 1901 determines that there is a media mismatch and proceeds to S908. In step S908, the CPU 1901 writes the determination result in the paper information and ends the process.

  According to the processing described above, when the operator displays a list of hold jobs, selects a plurality of jobs to be printed, and presses the update button 2104 before instructing the start of printing, the operator selects the media for each selected job. The mismatch is determined and the result is displayed.

  Even if there are many hold jobs, the number of jobs to be actually printed is usually not so large, and is about several to 100 at most. For this reason, the determination of the media mismatch can be performed within a few seconds even for a CPU with low performance.

  This media mismatch determination is performed only when the operator deliberately presses the update button 2104. For example, when the job list is scrolled to search for a job, the media mismatch determination is not performed. For this reason, the operator does not feel the stress that the display is slow.

  Further, when a job in which a media mismatch has occurred is selected and a paper replacement screen is displayed, for example, as shown in FIG. Further, if another paper is used to avoid a media mismatch, there is an advantage that it can be immediately determined whether the media mismatch is eliminated.

  As described above, according to the fifth embodiment, when a hold job is instructed to print, the paper in the paper feed stage designated by the job matches the paper actually stored in the paper feed stage. You can check whether you want to start before instructing to start printing. Further, since the media mismatch determination is performed only for the selected job and the media mismatch is not determined for the other jobs, the time and load required for determining the media mismatch can be reduced.

  Further, when there is a paper mismatch, it is possible to specify an alternative paper feed stage paper with a simple operation, thereby eliminating the troublesome operation of the operator.

[Embodiment 6]
In the above-described fifth embodiment, a plurality of jobs are selected from a plurality of hold jobs, and the update button 2104 is pressed to determine whether there is a media mismatch in the selected jobs. On the other hand, even if it is determined whether or not there is a media mismatch when executing a job at the moment when the job is selected, the processing time can be shortened if there is only one job. Embodiment 6 will be described below in which it is determined at the timing when a job is selected whether or not there is a media mismatch in the job. Note that the hardware configuration and system configuration of the apparatus according to the sixth embodiment are the same as those of the fifth embodiment, and a description thereof will be omitted.

  FIG. 27 is a flowchart for describing processing in which the controller 1900 of the printing apparatus 1800 according to the sixth embodiment of the present invention displays a job list screen. A program for executing this processing is stored in the program ROM 1903, and this processing is achieved by the CPU 1901 executing the program.

  Note that the processing of S1001 to S1008 and S1010 to S1016 is the same as S601 to S615 of the flowchart of FIG.

  The difference from the fifth embodiment is that in S1007, the CPU 1901 determines whether or not the job is already a target for multiple selection, and if it is not a target for multiple selection, the process proceeds to S1008, in addition to one of the multiple selection jobs. A selection order number is assigned and the process proceeds to S1009. On the other hand, if it is already a plurality of selection targets in S1007, the process proceeds to S1009. In step S1009, the CPU 1901 determines whether there is a media mismatch for the job. If there is a mismatch, the CPU 1901 adds an icon, redisplays the job list 2101, proceeds to step S1003, and waits for the next input.

  According to the processing described above, when the operator displays a list of hold jobs and selects a job to be printed, every time the job is selected, the operator determines the presence or absence of a media mismatch. Since such processing is performed for each job, even a non-high performance CPU can be processed for several tens of milliseconds. Therefore, it is considered that the operator does not feel stress because the display of the screen is delayed.

  Similarly to the fifth embodiment, when scrolling the job list to search for a job, it is not determined whether or not there is a media mismatch, so that there is no need to feel the stress that the display is slow.

  Also, if a UI that can select 100 jobs from the beginning or a UI that can specify a range is selected instead of selecting one by one from the job list, it takes time in seconds to determine whether there is a media mismatch. It may be. However, since it does not change as a whole when pressing the update button after selecting a job, it seems that the operator does not feel uncomfortable. Note that even if a job is selected, an operator who does not need to determine whether or not there is a media mismatch can be switched to the method of the fifth embodiment.

[Embodiment 7]
In the fifth embodiment described above, the presence / absence of a media mismatch is determined on the assumption that the paper used by the job has all the information such as the paper size, paper feed stage, and media type. However, there are not many cases in which all of this information is set on the paper of the job that is actually input. For example, there is a case where the paper feeder is not designated in the job designation and “AUTO” (automatic) is used, and the printing apparatus searches the paper feeder for paper suitable for the job and feeds the paper. In some cases, such as the front cover, the back cover, and the insertion sheet, the job is specified only by the paper feed stage, and the paper size and media type are not specified. In such a case, only the paper feed stages match and the paper size and the media type do not match, so that any job with an inserted sheet is determined to be a media mismatch.

  Another problem is that the paper size and media type are set as information on the paper set in the paper feed stage, but the actual printing device may be unable to feed paper because the paper feed stage is pulled out. . In some cases, the paper feed tray is closed, but no paper is stored therein (out of paper).

  Hereinafter, Embodiment 7 for determining the presence or absence of a media mismatch in these cases will be described. Note that the hardware configuration and system configuration of the apparatus according to the seventh embodiment are the same as those in the fifth embodiment, and a description thereof will be omitted.

  FIG. 28 is a flowchart for describing processing in which the controller 1900 of the printing apparatus 1800 according to the seventh embodiment of the present invention determines whether or not there is a media mismatch for each sheet. A program for executing this processing is stored in the program ROM 1903, and this processing is achieved by the CPU 1901 executing the program. This process corresponds to the details of the processes in S706 of FIG. 24 and S805 and S816 of FIG. Here, the processing from S1101 to S1104 is the same as S901 to S904 in FIG.

  In step S1105, the CPU 1901 determines whether the designation of the paper feed stage of the target job is “AUTO”. If so, the process advances to step S1106. In step S <b> 1106, the CPU 1901 determines whether any of the paper feed stages of the printing apparatus 1800 has a paper feed stage that accommodates paper whose specified paper size and media type match. If there is a matching paper feed stage, the process advances to step S1107, and the CPU 1901 determines whether the paper feed stage is out of paper. Further, if it is determined in step S1107 that the sheet is not out, the process advances to step S1108, and the CPU 1901 determines whether or not the sheet feed tray is in a drawn state. If it is determined that it is not in the pulled-out state (open), the process proceeds to S1109, and the CPU 1901 determines that there is no mismatch and proceeds to S1111.

  On the other hand, if none of the paper feed stages match the paper size and the media type in S1106, if the paper feed stage is out of paper in S1107, or if the paper feed stage is open in S1108, the process advances to S1110. move on. In step S1110, the CPU 1901 determines that there is a mismatch and proceeds to step S1111. The CPU 1901 writes the determination result in the paper information of the job, and ends this processing.

  In step S1105, the CPU 1901 proceeds to step S1112 if the paper feed stage designated by the target job is not “AUTO” but specifically designates a paper feed stage. Check the paper size and media type for the job. If neither of them is designated, the process advances to step S1113, and the CPU 1901 obtains information on the paper size and media type set for the designated paper feed stage from the paper setting information of the printing apparatus. Then, the paper size and media type set in the paper feed stage are adopted as the paper size and media type of the job, and the process advances to S1114. If it is determined in step S1112 that the job specifies one or both of the paper size and the media type, the process advances to step S1114.

  In step S <b> 1114, the CPU 1901 determines whether the paper size and the media type match for the paper in the designated paper feed stage. If there is a matching paper feed stage, the process proceeds to S1107, and if not, the process proceeds to S1110. In step S1110, the CPU 1901 determines that there is a mismatch and proceeds to step S1111. The CPU 1901 writes the determination result in the paper information of the job, and ends this processing.

  According to the processing described above, when the designation of the paper feed stage used by the held job is “AUTO”, the paper size and the media type match among the paper feed stages of the printing apparatus. Search for a paper feed tray containing paper. If there is a paper feed stage, a media mismatch does not occur, but if there is no matching paper in any paper feed stage, it is determined that there is a media mismatch.

  Also, if the paper used by the job includes paper that is not printed and just overlaid on the deliverable, such as the front cover, back cover, and insert paper, before determining whether there is a media mismatch, Set the specified paper size and media type for the specified paper source.

  As a result, if there is paper in the paper feed stage, there is no media mismatch, and if there is no paper, there is no media mismatch.

  Furthermore, if the paper feed stage is out of paper, or if the paper feed stage is open and cannot be fed as it is, it is determined that there is a media mismatch.
