Description

  The present invention relates to a data processing apparatus that is communicably connected to an image forming apparatus such as a printer, a multifunction peripheral, or a multifunction peripheral. The present invention also relates to an image forming system including a data processing apparatus and an image forming apparatus. Further, the present invention relates to a driver program used for the data processing apparatus and the image forming system.

  2. Description of the Related Art Conventionally, a printer or an image forming apparatus having a printer function (for example, a multifunction device or a copier) receives a print file from a data processing device (for example, a personal computer) as a user terminal and prints the file. Print based on the file. For example, a user uses a data processing apparatus to instruct printing of a file using application software (for example, electronic document browsing software), and then a driver program that is started is in a format that can be interpreted by a printer or the like. The print file is generated, and the print file is transmitted to a printer or the like.

In order to prevent the occurrence of an error in printing, a history when an abnormality occurs may be stored. An example of such a print control apparatus is described in Patent Document 1. Specifically, the print control device disclosed in Patent Document 1 causes an image corresponding to predetermined document data to be printed by a predetermined printing device, and when an abnormality occurs in printing by the printing device, the document data in which the printing abnormality has occurred is displayed. Corresponding history management means for accumulating the contents of a predetermined item related to the cause of the printing abnormality as history data, and history determination means for judging whether the contents of the items in the document data match the contents of the history data. When it is determined by the history determination means that they match, a control means is provided for stopping the printing when a print stop instruction is received before printing the document data. With this configuration, an error to be generated (printing abnormality) is to be avoided in advance (see Patent Document 1: Claim 1, paragraph [0020], etc.).
JP2007-241609

  Here, an error that occurs during printing is large in the size of the file data to be printed, so the size of the file for printing also increases (for example, high resolution image data), and image processing mounted in the image forming apparatus There is an overflow that does not fit in the working memory (work memory). Furthermore, this overflow is likely to occur when a function that increases the memory usage in the image forming apparatus, such as an aggregation process or an enlargement process, is used. For this reason, conventionally, when printing a file with a large data size, the user divides one file into pages that are predicted not to cause overflow (for example, a cut-and-try measure (for example, 100 pages). The file was printed 10 pages at a time).

  However, in this case, in order to print one file, the user has to issue a print instruction a plurality of times, which is complicated. In addition, it is necessary to determine the number of pages in one printing while taking into consideration the effect of function use that increases the memory usage. In addition, when the file in which the overflow occurs is a frequently used conference document, explanatory document, or document, it may be necessary to take this cut-and-try measure each time. Further, even if the user predicts that no overflow will occur and divides and prints in page units, an overflow may occur. If an overflow occurs, the image forming apparatus stops as an error, and the user must restart printing after taking error recovery measures (such as removal of paper in the conveyance path). In addition, if such printing failures are repeated, there is a problem that the user is uncomfortable and paper is wasted and time is wasted.

  Here, looking at the invention described in Patent Document 1, there is no description regarding the overflow of the memory, and the invention described in Patent Document 1 cannot cope with the overflow problem. Further, even if history data is left for overflow, the invention described in Patent Document 1 merely shows the history at the time of overflow occurrence and cannot prevent the occurrence of overflow. Therefore, even in the invention described in Patent Document 1, it is necessary to take a cut-and-try measure to avoid overflow, and no solution is shown for the above-described problem.

  In view of the above problems, an object of the present invention is to prevent the occurrence of overflow by automatically dividing a print file while referring to history data when printing a file in which overflow occurs. .

In the same case as the file that has caused an overflow before, a plurality of print files are generated by dividing the print file so that the size of one print file is less than the data amount, and the image forming apparatus Decided to send to.

  According to this configuration, when printing a large file in which an overflow occurs, the occurrence of an overflow can be prevented by automatically dividing the print file while referring to the history data. Therefore, if the history data can be obtained, printing can be completed without any cut-and-try operation, and thereafter, overflow occurs during printing, and printing is not repeated.

For the print function, a print setting confirmation screen for confirming the setting change is displayed on the display, and the setting input unit accepts the setting change. According to this configuration, since the user is prompted to cancel the setting of the print setting or change the setting that causes the overflow, the occurrence of the overflow can be further prevented.

  Further, the invention according to claim 3 is the invention according to claim 2, wherein the history data is printed when an overflow has occurred and when an overflow has occurred before but no overflow has occurred thereafter. Including the data indicating the presence / absence of setting of the predetermined printing function, and the control unit causes the display to display the function set when printing can be performed without overflow as a setting example display screen; did.

Therefore, the user can easily recognize the print function that should be canceled or changed the setting of the print settings, and the ease of making the user's judgment can be improved.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the control unit is configured such that the file for generating the print file is the same as the file that caused an overflow before. If the function set when printing is successful without overflow recorded in the history data and the function set in the current printing are the same, refer to the history data at the time of success. The print file is divided. According to this configuration, even if the print setting for increasing the memory usage in the image forming apparatus is made, it is possible to complete the printing without causing an overflow.

The image adding unit 85 includes, for example, watermark characters and copy-forgery-inhibited pattern character data appearing as a result of copying, for words such as “secret”, “copy prohibited”, “sample”, and “copy”. This is the part that performs the overlapping process. The resolution changing unit 86 is a part that changes the resolution of the image data. The color changing unit 87 is a part that performs processing relating to the print color, such as dropping image data from color to black and white. The page replacement unit 88 is a part that performs processing to change the order of pages in the case of bookbinding printing such as weekly magazine binding. As described above, at the time of printing, a printing file is transmitted from the terminal 2 to the multifunction device 3, the printing file is sent to the image processing unit 8 via the control unit 7, and the image processing unit 8 performs image processing.

(Print configuration)
Next, an example of items that can be set for printing in the terminal 2 of the present embodiment will be described with reference to FIGS. 5 and 6. 5 and 6 are diagrams illustrating an example of a print setting screen in the image forming system 1 according to the embodiment of the present invention. Although various print settings are possible in the terminal 2, in this description, the function that is problematic from the viewpoint of the usage amount of the image memory 81 in the multifunction machine 3 will be mainly described.

  First, FIG. 5A is an example of the basic setting screen 91 among the setting screens displayed when printing is performed on the terminal 2. For example, the basic setting screen 91 is displayed when the driver program 24 is activated when printing is instructed by each application software 25 in the terminal 2. Then, the user can set the function used for printing by inputting the setting screen displayed on the display 21 with the mouse 23 or the like.

  On the basic setting screen 91 shown in FIG. 5A, basic items that are frequently set by the user regarding printing, such as the paper size, the printing direction, and the number of copies, can be set. When the setting is completed, when the user presses the OK button 91a, generation of a print file and transmission to the multifunction device 3 are started. The cancel button 91b is pressed when printing is stopped. A plurality of tabs are arranged at the top of the screen. In FIG. 5A, the basic setting tab 91c is selected.

  When the user selects the layout tab 92 with the mouse 23 or the like, as shown in FIG. 5B, a booklet printing check box 92a, a page aggregation check box 92b, and a scaling check box 92c are displayed. The Although not shown in each figure, if selected, a letter-shaped check is entered. When the booklet printing check box 92a is selected and printing is performed, the page replacement unit 88 is operated to change the order of the pages in the printing file as in the case of a weekly magazine, and the booklet is folded in half. A printed material in the form can be obtained.

  When the page aggregation check box 92b is selected and printing is performed, the aggregation processing unit 83 is operated to execute a plurality of pages (for example, 2, 4, 6, 8, 9, 12, 16, 25). , 32 sheets, etc.) can be obtained. Then, in the pull-down menu format, the number of pages to be consolidated and the page layout can be set by inputting to the consolidated page number column 92d and the layout column 92e. It should be noted that hereinafter, in the description relating to aggregate printing, for example, it is described in a format of “Nin1 (N is the number of pages to be aggregated)” such as “2 in 1”. If the zooming check box 92c is selected and printing is performed, the zoom processing unit 84 is operated to specify the scaling factor in the scaling factor field 92f to obtain a printed matter in which the image has been enlarged or reduced. be able to.

  Next, when the user selects the print quality tab 93 with the mouse 23 or the like, a function relating to the print quality can be set as shown in FIG. In the quality setting field 93a, the print quality (for example, the higher the quality, the higher the resolution) can be set in a pull-down menu format. The multifunction device 3 is operated by the resolution changing unit 86 to form image data, and the resolution is changed by switching the on / off speed of the exposure unit 51 at the designated resolution. For example, the printing resolution can be changed to 1200 dpi, 600 dpi, 300 dpi, etc., and the user can define the quality.

  In the color item, for example, the color used in the printed material can be set in the pull-down menu format in the color mode column 93b. In the item of the color mode, for example, “color (using the four-color image forming unit 50)” and “monochrome (using only the black image forming unit 50K)” can be selected. The color changing unit 87 can form black and white image data from a print file containing color data.

  Next, when the user selects the extended function tab 94 with the mouse 23 or the like, a watermark button 94a and a security / watermark button 94b are displayed. If the watermark button 94a is pressed, a character to be inserted on another screen can be set (for example, “copy prohibited”). If printing is performed after setting, the image adding unit 85 functions and a watermark character is displayed. Can be obtained. Similarly, if the security / watermark button 94b is pressed, the image adding unit 85 functions to set a character to be embedded in another screen (for example, “secret”, “copy prohibited”, etc.). ) If printing is performed after the setting, a printed matter in which a copy-forgery-inhibited pattern character (appears in a copy when copied) can be obtained. For example, image data corresponding to each watermark is formed at each terminal 2, attached to a file for printing, can be transmitted to the multifunction device 3, and image data of each watermark within each multifunction device 3. May be generated.

  When the function for printing as described above is set by the driver program 24, the setting indicating the setting content is reflected in the print file or attached as setting data and transmitted. Then, the multifunction device 3 performs image processing based on the print file by, for example, instructing the image processing unit 8 to perform image processing to be executed by looking at the setting data, etc. The image to be printed is printed.

(Increase usage of image memory 81)
Next, although the image memory 81 of the image processing unit 8 receives the print file stored in the HDD 33a or the like of the multifunction machine 3, an increase in the usage amount of the image memory 81 due to print settings will be described.

  First, in aggregate printing, all image data of pages to be aggregated in a print file is secured in the area of the image memory 81. Thereafter, rotation processing and alignment processing are performed to adjust the direction and arrangement of images on the printed material. For example, in the case of 2 in 1, after rotating image data for two pages by 90 degrees, two pages are integrated into one page, and the zoom processing unit 84 or the like performs reduction processing. For example, in the case of 16 in 1, the image data area for 16 pages is secured, and the reduction process is performed while securing the page order (array within one page). Accordingly, it is necessary to secure an area of image data for a plurality of pages, and the memory usage in the image memory 81 increases due to the necessity of securing a working space for rotating work or the like.

  Next, in the enlargement process, since each page of the print file is enlarged in the enlargement process, the memory capacity required in the image memory 81 simply increases. For example, when an A4 size image is enlarged to A3, the area of the image is about twice, so if the resolution is the same, the memory usage is about twice.

  Next, in the booklet printing, the order of pages to be printed (image data) is changed. For example, the image memory 81 stores the image data for all the pages to be booklet printed in the image memory 81 and then changes the order. Replace. Therefore, a capacity sufficient to store all pages is required. Regarding the image quality, the higher the resolution, the larger the number of pixels for the same area, so the data amount per page increases.

  As for color and black and white, for example, if color has 256 gray levels for RGB, 8 bits for each color of R, G, and B are required per pixel. If so, 8 bits per pixel and 1 bit per pixel are sufficient if binarization is performed. Therefore, in the case of color, the size of the image data is larger than that of gray or a binarized image. For image addition, in addition to the image data for each page, watermark data for overlaying each image data and image data for security watermark are required. The usage amount of the image memory 81 increases by the amount of the added image.

  Therefore, the amount of memory used in the image memory 81 is increased by adding functions such as an aggregation function, an enlargement function, a booklet printing function, a color setting, a print quality (resolution), and an image addition, as compared with a case where printing is simply performed. is there. When these function settings are performed, the image memory 81 may overflow. Therefore, in the following, overflow of the image memory 81 and prevention of occurrence will be described.

(Historical data)
Next, based on FIG. 7, a measure for preventing the occurrence of overflow according to the embodiment of the present invention will be described. FIG. 7 is an example of history data (history list LS) when an overflow occurs according to the embodiment of the present invention.

  The image memory 81 mounted on the multifunction machine 3 is not unlimited, and is limited from the viewpoint of space and manufacturing cost. The multifunction machine 3 is usually equipped with a sufficient image memory 81. However, there are still cases where it is necessary to secure a print setting such as aggregation and an area for a print file that is sequentially sent. It may not fit in 81 and overflow (overflow).

  When an overflow occurs, appropriate printing cannot be continued, such as loss of image data in the overflowed portion, so that the control board 31 locks and stops the printing operation or the like. Specifically, an interrupt signal is input from the image processing unit 8 to the CPU 32 of the control board 31, the control board 31 stops the printing operation, and warning data indicating that an overflow has occurred in the terminal 2 that has transmitted the print file. Send. Upon receiving this warning data, the driver program 24 displays an error occurrence on the display 21 of the terminal 2.

  This overflow can occur when the size of the original file to be printed is large (for example, a PDF file of several hundred pages). Further, it may occur even when the data amount for one page in the print file is large. Further, for example, even when the multifunction device 3 is receiving the print file, the multifunction device 3 can start image formation of the previously received print file. However, the image memory 81 discards the image that is discarded upon completion of image formation. If there are more print files sent than data, there may be an overflow after printing to some extent.

  An overflow is also likely to occur when a printing function that increases the amount of use of the image memory 81 is set. In particular, when the data amount for one page is large, overflow is likely to occur when the print function is set. If an overflow occurs every time, for example, a file for a conference, an explanation, or the like that is frequently printed and a file related to the material is generated, the convenience of the user is impaired. Therefore, when an overflow occurs, the multifunction machine 3 of the present embodiment stores the status and print settings at that time as history data.

  In the terminal 2 of this embodiment, when printing the same file that has previously overflowed with reference to the history data, the printing file is automatically divided and transmitted to the multifunction device 3. Thereby, the user can prevent the occurrence of overflow by simply executing printing again without executing printing in a cut-and-try manner.

  Specifically, in the case where an overflow occurs, the multifunction machine 3 according to the present embodiment overflows from the first page in addition to information (for example, a file name) that specifies the file that caused the overflow as history data and print settings. It stores the number of pages that can be printed without printing, and the amount of data in the print file for the pages from the first page until the overflow occurs.

  In subsequent printing of the file causing the overflow, the terminal 2 (driver program 24) receives the history data stored in the storage unit 33 or the HDD 33a of the multifunction device 3 from the multifunction device 3, and there is no error. The print file is divided in units of pages while suppressing the size of one print file to a size equal to or smaller than the data amount (size) of the print file having the number of pages that can be executed. Further, referring to the history data, the print result and the print setting when the terminal 2 generates the print file by dividing it are combined with (corresponding to) the data that caused the overflow before and combined as the history data. The machine 3 stores it in the storage unit 33 and the like. The terminal acquires this history data at the time of printing.

  That is, the terminal 2 controls the apparatus, and when an overflow occurs in which the data cannot be stored in the image memory 81 mounted on the multifunction machine 3, the file name that caused the overflow and the top of the print file A control unit 7 that acquires history data including information indicating the amount of data from the page to the page that could be printed by the MFP 3 without overflowing by communicating with the MFP 3 (the acquired history data is the RAM 73 or the HDD 74). And the control unit 7 prints one file when the file to be generated by the confirmation based on the history data is the same as the file that caused the overflow before. Multiple print files are divided into pages so that the size of the print file is less than the amount of data, and sent to the MFP 3 That.

  An example of such history data is shown in FIG. In the history data (history list LS) shown in FIG. 7, the file name to be printed when an overflow occurs, whether or not printing has been completed without overflow, the number of pages that could be printed until the overflow occurred, the first page To the page printed without overflow (data amount, illustrated as X1 to X5 in FIG. 7), the size of the largest of the divided print files when no overflow occurs (Data amount, exemplified as Y1 to Y3), print setting contents such as aggregate printing, and the like are stored in the storage unit 33 of the multifunction machine 3 as history data. Specifically, the history data is stored for an aggregate printing function, an enlarged printing function, a resolution setting function, a printing color setting function, an image addition function, and a page replacement function. Further functions may be added.

  As shown in FIG. 7, for a file that has overflowed even once, the history is accumulated both when the overflow occurs and when the file can be printed without overflow. Then, for example, as shown in the second line (numbered line 1-2) in the table of FIG. 7, the history data in the first line (numbered line 1-1) is printed without overflow in the history data. Since the print file is divided by referring to the data amount (X1 value) of the print file for the number of pages that can be executed, if the print settings are the same, printing will not occur after the next time. Can do. For example, among the divided print files, the second and subsequent print files can be transmitted after all of the previous print files have been printed and the image memory 81 is empty.

  Here, when the print settings are different, the print file may be divided by referring to the previous history data. However, how much the use amount of the image memory 81 increases depending on the print setting may depend on what kind of file is printed. Also, there may be no overflow depending on the print settings. Therefore, it is difficult to predict whether an overflow will occur. Therefore, in the MFP 3 of this embodiment, when the print settings are different, the print file is not divided for the time being. Then, history data is accumulated.

  For example, in the second row of the table (the row of number 1-2), the central printing is not performed and the monochrome printing is performed, whereas in the third row of the table (the row of number 1-3), 2in1 and Color printing and print settings are different. Further, in the fourth row of the table (numbered 1-4), the page is replaced by adding a watermark image or printing a booklet, and the settings are different from those of numbers 1-2 and 1-3. Therefore, overflow may occur even when the print file is divided by referring to the history of the second line (numbered line 1-2) of the table.

  However, in the MFP 3 of the present embodiment, the history data is collected, and for the settings once printed, the number of pages that can be printed without overflow and the size of the print file for the number of pages are set. After that, if the same print settings are made for the same file and printing is executed, printing can be performed without causing overflow. For example, line number 1-2 or line number 1-5

  Although such an overflow prevention measure is also sufficiently effective, the terminal 2 (driver program 24) of the present embodiment acquires history data from the storage unit 33 of the multifunction machine 3 and prints it in order to prevent overflow. If the file to be generated has caused an overflow in the past, confirm the change of the print setting with the user and suggest it. Therefore, this will be described below.

(Proposal for changing print settings)
Next, based on FIG. 8 and FIG. 9, confirmation and proposal of print setting change according to the embodiment of the present invention will be described. FIG. 8 is a diagram illustrating an example of a setting screen as an example of an overflow prevention measure according to the embodiment of the present invention. FIG. 9 is a diagram showing an example of a screen showing past printing success examples according to the embodiment of the present invention.

  First, FIG. 8 will be described. FIG. 8 shows an example of a print setting confirmation screen 95 displayed on the display 21 of the terminal 2 when the terminal 2 communicates with the multifunction device 3 and recognizes that the file to be printed has previously overflowed. Is shown.

  In the print setting confirmation screen 95, a display for calling attention to the fact that an overflow has occurred in the file to be printed before is displayed in the uppermost part. On the print setting confirmation screen 95, print settings that increase the usage amount of the image memory 81 in the multifunction machine 3 are displayed. In the area assigned to each print setting, a current setting display field 96 set by the user and a setting change field 97 for displaying the changed setting by a pull-down method are arranged. Further, for example, a description of how the setting is changed and the overflow is less likely to occur is also displayed.

  In the current setting display field 96a of the area F1 related to the aggregate setting, the aggregate print setting previously set by the user using the driver program 24 is displayed (FIG. 8 shows the case of 16 in 1 as an example). Then, as the number of aggregations increases, the number of pages to be stored in the image memory 81 increases, so that the usage amount of the image memory 81 tends to increase. Therefore, the user can input a change selection for reducing the number of aggregations in the setting change field 97a. Note that FIG. 8 shows an example in which the amount of use of the image memory 81 is reduced by reducing to 4 in 1.

  Next, in the current setting display field 96b of the area F2 relating to the enlargement setting, the enlargement print setting previously set by the user in the driver program 24 is displayed (FIG. 8 shows the case of 200% as an example). . If the image memory 81 is enlarged, the amount of use of the image memory 81 is increased. For example, the user can input a change to reduce the degree of enlargement in the setting change field 97b. FIG. 8 shows an example in which the usage amount of the image memory 81 is reduced to 100% (same size).

  In the current setting display field 96c in the resolution-related area F3, the resolution setting previously set by the user in the driver program 24 is displayed (FIG. 8 shows the case of high image quality as an example). In the case of high image quality, the number of pixels for the same area increases, so the amount of use of the image memory 81 increases. Therefore, for example, the user can input a change to reduce the resolution in the setting change field 97c. FIG. 8 shows an example in which the usage amount of the image memory 81 is reduced to normal.

  In the current setting display field 96d in the color setting area F4, the print color setting previously set by the user in the driver program 24 is displayed (FIG. 8 shows the case of color as an example). In color, the number of bits required for one pixel is larger than in the case of monochrome. Therefore, for example, as shown in FIG. 8, the user can input a change in the setting change field 97d to reduce the usage amount of the image memory 81 to black and white.

  In addition, in the current setting display field 96e of the area F5 related to image addition, the setting for image addition previously set by the user in the driver program 24 is displayed (FIG. 8 shows the case of a watermark as an example). When an image is added, the usage amount of the image memory 81 increases. Therefore, for example, as shown in FIG. 8, the user can input a change in the setting change field 97 e to eliminate the addition of an image and reduce the usage amount of the image memory 81.

  In the current setting display field 96f of the area F6 related to page replacement, the image addition setting previously set by the user in the driver program 24 is displayed (FIG. 8 shows the case of booklet printing as an example). When the pages are replaced, the usage amount of the image memory 81 increases to secure a work area. Therefore, for example, as shown in FIG. 8, the user can input a change in the setting change field 97 f to eliminate page replacement and reduce the usage amount of the image memory 81.

  That is, the terminal 2 includes an input / output device such as a display 21 for displaying a setting screen for setting printing in the multifunction device 3 and a keyboard 22 and a mouse 23 for setting a printing function to be used. The control unit 7 uses a predetermined print function as a result that the MFP 3 is likely to cause an overflow when the file to be generated is the same as the file that caused the overflow before. A print setting confirmation screen 95 for confirming the setting change is displayed on the display 21 and the setting change by the keyboard 22 or the like is accepted.

  In this way, when printing a file that has previously overflowed, the terminal 2 proposes a change in print settings so that the amount of use of the image memory 81 is as small as possible. It is possible to recognize the possibility of the occurrence of overflow and to prevent the occurrence of overflow.

  Furthermore, a link 98 can be provided at the bottom of the print setting confirmation screen 95 for displaying a print setting example in which no overflow has occurred in the history data. When the link 98 is clicked with the mouse 23 or the like, a setting example display screen 99 in which printing can be executed without overflow in the past as shown in FIG. 9 is displayed on the display 21 of the terminal 2.

  That is, the history data includes data indicating whether or not a predetermined print function has been set when an overflow has occurred, and when an overflow has occurred before and printing can be performed without overflow thereafter. Then, the control unit 7 causes the display 21 to display the function set when printing is possible without overflow as the setting example display screen 99. The user can change the print setting on the print setting confirmation screen 95 shown in FIG. 8 with reference to an example in which printing can be performed without overflow in the past. If the same setting as in the past is made, it is sufficient to divide the print file in the same manner as in the previous time by referring to the history data. In this case, the file can be printed without causing overflow. .

  Note that it is extremely rare that the size of the data of the first page of the print file is too large and overflow occurs, and even one page cannot be printed. Even in such a case, since overflow has occurred, it is stored as history data (in this case, the column for error-free pages and the column for error-free data amount in the history list shown in FIG. 7 are zero). . When printing is attempted again for a file that could not be printed, for example, the driver program 24 displays a print setting confirmation screen 95 and recommends a setting for reducing the amount of use of the image memory 81. become. If an overflow occurs even if all the print settings are canceled, the installed image memory 81 is essentially insufficient, and it is required to increase the image memory 81.

(Control flow)
Next, an example of a control flow for preventing overflow according to the embodiment of the present invention will be described with reference to FIG. FIG. 10 is a flowchart illustrating an example of overflow prevention control according to the embodiment of the present invention.

  First, the start in FIG. 10 is a point in time when the user gives an instruction to perform printing by using the multifunction machine 3 as a printer with each application software 25. Then, in response to the print execution instruction, the driver program 24 is activated on the terminal 2, and the terminal 2 confirms the file to be printed (step # 1). Next, the terminal 2 inquires the multifunction device 3 about the file to be printed and checks whether there is an overflow occurrence history (step # 2). If there is no history (No in Step # 2), printing is performed without dividing the print file (Step # 3), and the multi function device 3 checks whether or not an overflow has occurred (Step # 4). If an overflow occurs (Yes in step # 4), the multi function device 3 stores the history as history data (step # 5). If no overflow occurs (No in step # 4), the control process is terminated (END).

  On the other hand, if there is an overflow occurrence history (Yes in step # 2), the terminal 2 receives and acquires the history data (history list LS) of the file to be printed from the multifunction device 3, and stores it in the RAM 73, for example. (Step # 6). Then, the terminal 2 refers to and confirms the history data, and displays the print setting confirmation screen 95 on the display 21 (step # 7).

  Then, the terminal 2 confirms the setting on the print setting confirmation screen 95, and confirms whether the setting content matches the setting of the past successful example that has been printed without causing an overflow (step # 8). If it matches the past success example (Yes in step # 8), for example, the size of the largest print file in the current print and the past success example is the same with reference to the past success example. Thus, the size of each print file is determined, and the print file is divided (step # 9). That is, the control unit 7 sets the function that is set when the file for generating the print file is the same as the file that caused the overflow before and the printing is successfully performed without the overflow recorded in the history data. If the functions set in the current printing are the same, the history file at the time of success is referred to, and the print file is divided in the same manner.

  On the other hand, if the current print setting does not match the past success example (No in step # 8), it is confirmed whether there is a failure example with the same setting in the history data (step # 10). . If there is a failure example (Yes in step # 10), the print file is divided by setting the size of the print file as many as the number of pages that could be printed without overflow (step # 10). 11). If there is no failure example (No in Step # 10), the process proceeds to Step # 3, and history data is obtained.

  After the print file is divided (steps # 9 and 11), the terminal 2 sequentially transmits the print file to the multi-function device 3, and the multi-function device 3 performs, for example, the second and later of the divided files. A print file is received every time printing of the previously received print file is completed, and a print result and its setting are added to the history data (step # 12 → end). Then, after image processing or the like is performed, printing is performed.

  Thus, according to the present embodiment, when printing a large file in which overflow occurs, the occurrence of overflow can be prevented by automatically dividing the print file while referring to the history data. . Therefore, if the history data can be obtained, the cut and try operation is not performed at all, and thereafter, an overflow occurs during printing, and printing is not performed again. Accordingly, there is no waste of paper and waste of time (deterioration of productivity of the image forming apparatus), and there is no discomfort to the user, so that convenience for the user can be greatly improved.

  Further, since the user is prompted to change the print setting that causes the overflow on the print setting confirmation screen 95, the occurrence of the overflow can be further prevented. On the setting example display screen 99, it is possible to indicate to the user the criteria for determining whether or not an overflow will occur or what overflow will occur if any printing function is set. Therefore, the user can easily recognize the print function that should be canceled or changed the setting of the print settings, and the ease of making the user's judgment can be improved.

  Next, another embodiment will be described. In the above embodiment, the MFP 3 stores the number of pages that can be printed from the first page until an overflow occurs and the amount of data for that page as history data, but instead, until an overflow occurs from the first page. The number of pages that the multi-function device 3 can receive from the terminal 2 and the data amount for the pages may be used as history data.

  In the above-described embodiment, the case where the multifunction machine 3 stores the history data is shown from the viewpoint of sharing the history data so that all the joint users of the multifunction machine 3 can accumulate and use the history data. Each terminal 2 may store history data in a nonvolatile manner (for example, stored in the HDD 74). Accordingly, it is possible to divide a print file that does not cause overflow without performing communication with the multifunction device 3.

  In the above-described embodiment, the operation of the terminal 2 of the data processing apparatus has been mainly described. However, the present invention is an image forming system including a data processing apparatus and an image forming apparatus (for example, the multifunction machine 3), and It can also be understood as an invention of a driver program for a data processing device.

  The embodiment of the present invention has been described above, but the scope of the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention.

  The present invention can be applied to a data processing apparatus connected to an image forming apparatus, an image forming system including the image forming apparatus and the data processing apparatus, and a driver program installed in a terminal.
