Embodiments for Carrying Out the Invention

[0009] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the disclosed matters, and not all combinations of the features described in the following embodiments are essential for the solution means of the present disclosure. The same reference numerals are assigned to the same components.

[0010] (Overview) At the time of copy printing, there is known an enlarged printing function in which the original image scanned and read is enlarged, printed separately on a plurality of printing media, and one printed matter is created by bonding the printing media. In the enlarged printing function for roll paper among the printing media, printing is performed with the output paper size set within the size range of the roll paper to be installed. Also, at the time of enlarged printing, it is necessary to set the direction in which the printing media is divided. Depending on the output paper size and the dividing direction, the number of printed copies of the printing media obtained from the roll paper changes. For switching the dividing direction, the user selects whether to divide the long side portion or the short side portion of the image to be enlarged, and the image forming apparatus changes the number of divisions according to the dividing direction.

[0011] In general copy printing, this number of divisions is calculated based on the original image for enlarged printing after it is read, and the size of the paper after enlarged printing and the dividing direction, and is substantially displayed as the remaining number of printed copies at the timing during printing execution. In this way, after the actual printing process has started, the user is in a state where the number of divisions is substantially notified, and the user cannot grasp whether the division will be performed with the desired number of divisions before printing starts.

[0012] As described above, even in the form of printing as a bonding guide, it has not been possible to notify the user of the number of divisions before enlargement printing. In the present disclosure, the number of divisions is determined before starting printing at the time of copy printing, and the determined number of divisions is notified to the user. According to this operation, reprinting can be avoided.

[0013] (First Embodiment) FIG. 1 is a diagram showing an external appearance example of an image forming apparatus 1 according to the first embodiment. FIG. 2 is an enlarged front view of the operation unit 120 of FIG. 1. FIG. 3 is a block diagram showing the configuration of the control system of the image forming apparatus 1 of FIG. 1. As shown in FIG. 1, an original platen 101, a roll paper feeding unit 104, and a cut paper feeding unit 103 are provided on the upper part of the housing 100 of the image forming apparatus 1. A memory card slot 110, an operation unit 120, and a paper discharge tray 105 are provided on the front part of the housing 100 of the image forming apparatus 1. The original platen 101 is a glassy transparent table. Below the original platen 101, a scanner 325 of FIG. 3 is provided. An openable and closable original cover 102 is provided on the original platen 101. When an original is placed on the original platen 101, the original is read by the scanner 325. The original cover 102 prevents the reading light from leaking to the outside when reading the original by the scanner 325. Thus, the image forming apparatus 1 of FIG. 1 is shown as an example of a multifunction printer having a reading function such as the scanner 325 of FIG. 3.

[0014] The cut paper feeding unit 103 is provided with a cut paper insertion slot. The size and shape of the cut paper insertion slot accommodate various sizes of cut paper. Cut paper is set in the cut paper feeding unit 103 as a recording medium. For example, recording media with finished dimensions conforming to various standards can be set in the cut paper feeding unit 103. Various standards for cut paper include, for example, A-series, B-series, and ANSI standards. ANSI includes, for example, the LTR standard standardized as ANSI A. The roll paper feeding unit 104 is provided with a roll paper insertion slot. The size and shape of the roll paper insertion slot accommodate various sizes of roll paper. Roll paper is set in the roll paper feeding unit 104 as a recording medium. For example, recording media with finished dimensions conforming to various standards can also be set in the roll paper feeding unit 104. Various standards for roll paper include, for example, A1 rolls, A2 rolls, 24-inch rolls, 18-inch rolls, and 17-inch rolls. It is also possible to set cut paper in the cut paper feeding unit 103 and simultaneously set roll paper in the roll paper feeding unit 104. The recording medium set in the cut paper feeding unit 103 or the roll paper feeding unit 104 is transported to the printing unit having the print head 330 shown in Figure 3, printing is performed, and the printed material is discharged from the output tray 105 shown in Figure 1. A memory card slot 110 and an operation unit 120 are provided above the output tray 105. The memory card slot 110 is provided with an insertion slot for a memory card 323. When the memory card 323 is inserted into the memory card slot 110, the image data stored on the memory card 323 is read, and printing of the read image data becomes possible. The operation unit 120 is a user interface that accepts operations from the user. Based on the operations from the user received by the operation unit 120, various setting values ​​are accepted and various processes are initiated. In this embodiment, an inkjet system is assumed, but it is not particularly limited to this. Electrophotographic methods are also acceptable.

[0015] Figure 2 is an enlarged front view of the operation unit 120 of Figure 1. As shown in Figure 2, the operation unit 120 includes a power button 210A, a stop button 210B, a start button 210C, a display unit 230, and a touch panel unit 220. The display unit 230 displays a graphical user interface (hereinafter referred to as GUI). The display unit 230 is made of, for example, a glass panel. The touch panel unit 220 is laminated on the back surface of the display unit 230. The touch panel unit 220 is made of a touch panel, a liquid crystal panel, etc. The touch panel unit 220 accepts operation of the GUI. The display unit 201 displays the status of the image forming apparatus 1, print settings, image previews read from the memory card, etc., in GUI form. The status of the image forming apparatus 1 is, for example, ink information or information on the stored recording medium. The ink information is, for example, information indicating the type of ink such as cyan, magenta, yellow, and black, and the remaining amount of ink. The recording medium information is, for example, information indicating the size of the roll paper stored in the roll paper feed unit 104. Examples of roll paper sizes include 18-inch rolls, 24-inch rolls, A1-inch rolls, and A2-inch rolls. The touch panel unit 220 accepts user operations on the GUI displayed on the display unit 230. For example, the user can change print settings, etc., via the touch panel unit 220. The touch panel unit 220 can also accept user operations from other means. For example, when the user presses the power button 210A, the power to the image forming apparatus 1 is turned on or off. When the user presses the start button 210C, the operation of the image forming apparatus 1 (copying or printing) begins. The operation of the image forming apparatus 1 is, for example, copying or printing image data to the recording medium. When the user presses the stop button 210B, the operation to the image forming apparatus 1 is canceled or the operation of the image forming apparatus 1 is stopped. Note that when referring collectively to the various buttons in Figure 2, such as the power button 210A, stop button 210B, and start button 210C, they will be called operation buttons 210.Note that the operation buttons 210 shown in Figure 2 are just examples and are not limited to these. Furthermore, a GUI corresponding to the operation buttons 210 may be displayed on the display unit 230, and the GUI corresponding to the operation buttons 210 may be operated by the user via the touch panel unit 220.

[0016] Figure 3 is a block diagram showing the configuration of the control system of the image forming apparatus 1 shown in Figure 1. The image forming apparatus 1 comprises a CPU 301, program memory 303, data memory 304, panel control circuit 317, memory card control circuit 321, and internal bus 302 as the configuration of the control system. The CPU 301, program memory 303, data memory 304, panel control circuit 317, and memory card control circuit 321 are connected via the internal bus 302. The CPU 301 executes processing according to the contents of the ROM-type program memory 303 and the contents of the RAM-type data memory 304, for example, via one internal bus 302. The data memory 304 is used as either a work memory 305 or an image memory 306. The work memory 305 can temporarily store parameters necessary for various processes used when the CPU 301 executes a control program. The image memory 306 stores image data formed on a recording medium.

[0017] Furthermore, the image forming apparatus 1 includes an interface control circuit 307, a motor control circuit 309, a head control circuit 313, a sensor control circuit 314, and a scanner control circuit 324 as part of its control system configuration. The CPU 301 controls the interface control circuit 307 and can receive print job data from the host computer 308 connected via an external interface. Alternatively, the CPU 301 can also control the interface control circuit 307 and notify the host computer 308 connected via an external interface of the status of the image forming apparatus 1. The CPU 301 can control various motors that drive the mechanisms of the image forming apparatus 1 via the motor control circuit 309. Examples of these motors include a transport motor 310, a carriage motor 311 (also referred to as a CR motor 311), and a recovery motor 312. The transport motor 310 drives the paper feed roller, transport roller, and paper discharge roller located inside the housing 100, transporting the recording medium from the paper feed unit to the paper discharge tray 105. The CR motor 311 reciprocates the carriage that holds the print head 330. The recovery motor 312 drives the head recovery mechanism and performs recovery operations to maintain the print head 330 in an appropriate state by controlling it in synchronization with the carriage drive. The CPU 301 can control the print head 330 via the head control circuit 313. By controlling the print head 330 in synchronization with the reciprocating movement of the carriage, an image is formed on the recording medium. The CPU 301 can control the sensor light source 341 of the paper sensor 340 and acquire the output voltage of the optical sensor 343 via the sensor control circuit 314. The cassette sensors 326 and 327 consist of a photo interrupter and a mechanical switch. The cassette sensors 326 and 327 detect when the user inserts or removes the paper feed unit, and the CPU 301 can acquire this detection via the sensor control circuit 314. The CPU 301 controls the operation unit 120 via the panel control circuit 317. It can display desired information on the display unit 230 located on the operation unit 120 and monitor user operations on the operation buttons 210 on the operation unit 120.The CPU 301 can control the scanner 325 via the scanner control circuit 324 and read the image of the document placed on the document glass 101. The CPU 301 can read and write various files in the memory card 323 inserted in the memory card slot 110 via the memory card control circuit 321. The image read by the scanner 325 is stored in the image memory 306 in the data memory 304 and can then be sent to the host computer 308 or saved as an image file on the memory card 323. It is also possible to use the image read by the scanner 325 as a copy function by controlling the printing mechanism to print it directly. The CPU 301 may be in the form of a microprocessor made of a single microchip, or it may be in the form of a central processing unit in cooperation with other CPUs.

[0018] (Print settings information) Figure 4 shows an example of the display of the display unit 230 in Figure 2. In the example in Figure 4, a use case is assumed in which the user selects the copy function via the GUI displayed on the display unit 230, and then selects the enlarged print setting from the copy function type options. Window 400 contains multiple panes. The multiple panes display the print setting information set by the user. The print setting information includes recording medium information, print quantity information, and size information after enlarged printing. Each of the multiple panes is located in the upper left, upper right, center, and lower left, respectively. The pane in the upper left displays the recording medium information 401, including the size and type of roll paper to be printed. In the example in Figure 4, the recording medium information 401, which indicates that the roll paper size is A1 roll paper and the paper type is plain paper, is displayed in the upper left pane. The upper right pane displays the print quantity information. In the example in Figure 4, the print quantity information, which indicates that the print quantity is 1 sheet, is displayed in the upper right pane. The center pane displays the print icon 403 and the output size 404. The print icon 403 is set based on the enlarged print setting information. The print icon 403 is displayed as an icon that mimics the division position and number of divisions of the cut-sheet original image. For example, print icon 403 shows an example of dividing the short side of a cut-sheet original image into two parts. Furthermore, the cut-sheet original image used for print icon 403 does not have to be the original image intended for copying, as it only needs to intuitively indicate the division position and number of divisions. In other words, print icon 403 can be any icon image that mimics the divided form of the original image. Output size 404 shows the size information after enlargement printing based on the recording medium information. Output size 404 indicates that the LTR cut-sheet original image will be enlarged and printed to become the final ANSI-E output. The lower left pane shows a print settings button 405 for switching the enlargement printing settings. By pressing the print settings button 405, the user can transition the current window 400 to a window that updates the print settings information.

[0019] (Printed in two sections and enlarged) Figure 5 is a schematic diagram illustrating the series of steps involved in generating the final product by dividing the original document into two parts using the image forming apparatus 1 shown in Figure 1, then enlarging and printing them, and finally joining them together. Figure 5(a) shows an example of a cut-sheet original image generated when the cut-sheet original document is scanned by the scanner 325. Figure 5(b) shows an example of the cut-sheet original image in Figure 5(a) being divided and enlarged. Note that Figure 5 does not accurately reflect the enlargement ratio. Figure 5 is used as a diagram to intuitively illustrate enlarged and divided printing. Here, we consider a use case in which the long side of an A4 cut-sheet original image is divided into two parts, enlarged and printed onto A1 roll paper, and then the enlarged prints are joined together to obtain an A0 final product. In this use case, the divided original document fits within the width of the A1 roll paper. Therefore, by joining the divided original document, it is possible to obtain an A0 final product while maintaining the aspect ratio of the cut-sheet original image. However, if the two-part original document does not fit within the width of an A1 roll of paper, it is necessary to divide the long side of the A4 cut-sheet original document into three parts instead of two to maintain the aspect ratio of the cut-sheet original image. Next, we will explain an example of dividing the long side of an A4 cut-sheet original document into three parts.

[0020] (3-part and enlarged print) Figure 6 is a schematic diagram illustrating the series of steps involved in generating the final product by dividing the original document into three parts using the image forming apparatus 1 in Figure 1, then enlarging and printing them, and finally joining them together. Figure 6(a) shows an example of a cut-sheet original document image generated when the cut-sheet original document is scanned by the scanner 325. Figure 6(b) shows an example of the cut-sheet original document image in Figure 6(a) being divided and enlarged. Note that Figure 6 does not accurately reflect the enlargement ratio. Figure 6 is used as a diagram to intuitively illustrate enlarged and divided printing. Here, we consider a use case in which the long side of an A4 cut-sheet original document image is divided into three parts, enlarged and printed onto A1 roll paper, and then the enlarged prints are joined together to obtain an A0 final product. In this use case, the divided original document fits within the width of the A1 roll paper. Therefore, by joining the divided original document, it is possible to obtain an A0 final product while maintaining the aspect ratio of the cut-sheet original document image. Even if the document is divided into four or more sections, if the divided sections fit within the width of an A1 roll of paper, but the two-sectioned section does not, then a three-sectioned section is preferable from the standpoint of not wasting roll paper.

[0021] (Enlarged printing on roll paper) Figure 7 shows examples of combinations of roll paper sizes and enlargement division methods used for enlarged printing. Note that A0 size is 841mm x 1189mm. A4 size is 210mm x 297mm. The roll width of A1 roll paper is 594mm. The roll width of A2 roll paper is 420mm. The roll width of 24-inch roll paper is 609.6mm. The roll width of 17-inch roll paper is 431.8mm. As shown in Figure 7, there are two types of division: long-side division and short-side division. Furthermore, long-side division includes 2-way and 3-way division. In Figure 7, use cases that result in 3-way division include A2 roll paper, 18-inch roll paper, and 17-inch roll paper. In other words, when enlarging an A4 cut sheet original by dividing its long side in half and then printing it on A2 roll paper, 18-inch roll paper, or 17-inch roll paper, the divided original will not fit within the width of each roll paper. This means that the aspect ratio of the final A0 output cannot be maintained at the same aspect ratio as the A4 cut sheet original. Figure 7, correlation diagram 700, shows the correlation between roll paper size and enlargement division method. Correlation diagram 700 includes roll paper size pattern 701, enlargement division method pattern 702, and print icon 703. Roll paper size pattern 701 includes patterns for A1 roll paper, A2 roll paper, 24-inch roll paper, 18-inch roll paper, and 17-inch roll paper. Enlargement division method pattern 702 includes long-side division and short-side division. The print icon 703 is an icon determined based on the roll paper size pattern 701 and the enlargement and division method pattern 702, and it displays how the paper will be enlarged and divided. Next, referring to Figure 7, examples of how the number of divisions determined for each division setting is displayed will be explained using Figures 8 and 9.

[0022] Figure 8 shows an example of how the print icon 803 changes when switching from short-side splitting to long-side splitting. Figure 8(a) shows an example of window 800 displaying print setting information. Figure 8(b) shows an example of print setting window 810 displayed when the print setting button 601 in Figure 8(a) is pressed. Figure 8(c) shows an example of splitting method setting window 820. Figure 8(d) shows an example of window 800 after the print setting information has been updated. In this embodiment, it is assumed that the display unit 230 in Figure 2 supports GUI, but it is not limited to this. The display unit 230 in Figure 2 may also support CUI (Character User Interface). In this case, display items can be appropriately selected using hardware keys (not shown). Thus, it is possible to update print settings even with a simple UI (User Interface) such as CUI. Furthermore, a simple UI such as CUI can be used to support IoT devices that require low power consumption.

[0023] In the example shown in Figure 8(a), print settings information is displayed via a GUI similar to that in the example shown in Figure 4. For example, the upper left pane displays recording medium information 801, indicating that the roll paper size is A2 roll paper and the paper type is plain paper. The upper right pane displays print count information 802, indicating that the number of prints is 1. The center pane displays a print icon 803 and an output size 804. The print icon 803 shows an example of dividing the cut paper original image into two sections along the short side. The output size 804 indicates that the LTR cut paper original image will be enlarged and printed to produce the final ANSI-E output. The lower left pane displays a print settings button 805. When the print settings button 805 is pressed, the print settings window 810 shown in Figure 8(b) is displayed.

[0024] In the example shown in Figure 8(b), the current print settings information is displayed in the print settings window 810. The print settings window 810 includes a magnification menu, a paper feed position menu, a print quality menu, and a split method menu 813. Referring to the magnification menu, the magnification is set to 1:1. Referring to the paper feed position menu, the paper feed position is set to the roll paper position. Referring to the print quality menu, the print quality is set to standard. Referring to the split method menu 813, the split method is set to short-side split. When the split method menu 813 is selected by the user, the split method setting window 820 shown in Figure 8(c) is displayed.

[0025] In the example shown in Figure 8(c), the selectable division methods are displayed as a division method list in the division method settings window 820. The division method list includes options for short-side division and long-side division 825. When item 825 is selected, window 800 shown in Figure 8(d) is displayed. The print icon 803 in Figure 8(d) is displayed in a configuration where the long side is divided into three sections.

[0026] Figure 9 is a flowchart illustrating the display process of the print icon according to the selection in Figure 8. The process shown in Figure 9 is executed when the window 800, which displays the print settings information, is operated. Note that some or all of the functions of the steps in Figure 9 may be implemented by hardware such as an ASIC or electronic circuit. The symbol "S" in the description of each process means that it is a step in the flowchart. It is also assumed that the size of the roll paper to be enlarged and the size of the final output are set in advance.

[0027] In S901, the CPU 301 determines whether a division method has been selected. There are two division methods: long-side division and short-side division. Short-side division divides the short side of the original image into two parts, and since it fits within the width of the pre-selected roll paper, it is possible to obtain the final output while maintaining the aspect ratio of the original image. On the other hand, long-side division divides the long side of the original image, and first attempts to divide it into two parts. If the size obtained by dividing it into two parts does not fit within the width of the pre-selected roll paper, it is impossible to obtain the final output while maintaining the aspect ratio of the original image. In this case, it attempts to divide it into three parts. Therefore, the subsequent processing changes depending on the division method selected by the user, so the CPU 301 first determines whether a division method has been selected by the user. If a division method has been selected, the CPU 301 proceeds to the S902 process. If a division method has not been selected, the CPU 301 continues the S901 process. CPU301 performs the processing of S901 based on the user's actions in the partition method setting window 820 shown in Figure 8(c).

[0028] In S902, the CPU 301 determines whether the paper is divided along the longer side. If it is divided along the longer side, the CPU 301 determines whether it will be divided into two or three sections, depending on the roll paper size, as shown in Figure 7. If the CPU 301 determines that it is divided along the longer side, it proceeds from S902 to S903. In S903, the CPU 301 determines whether the print paper size is A2 roll paper, 17-inch roll paper, or 18-inch roll paper. If the print paper size is determined to be A2 roll paper, 17-inch roll paper, or 18-inch roll paper, the CPU 301 proceeds from S903 to S904. In S904, the CPU 301 displays a print icon indicating a three-section division and terminates the process. If the print paper size is neither A2 roll paper, 17-inch roll paper, nor 18-inch roll paper, the CPU 301 proceeds from S903 to S905. In other words, CPU301 uses S903's processing to extract the parts of the long-side division that cannot be divided into two, so that parts that can be divided into two are processed with two divisions, and only when absolutely necessary are parts processed with three divisions.

[0029] On the other hand, if CPU301 determines that it is not a long-side split, it proceeds from processing S902 to processing S905. In S905, CPU301 displays a print icon for a two-way split and terminates processing. In other words, the processing for the short-side split is executed.

[0030] (Notification method) In the S904 and S905 processes, the number of divisions is notified to the user by displaying a print icon 1003, but the user can also know the number of divisions in other ways. For example, the number of divisions may be notified to the user by voice. In this case, the image forming apparatus 1 only needs to have a voice synthesis function and a speaker. Alternatively, the operation unit 120 may vibrate according to the number of divisions. In this case, a vibrator may be provided inside the operation unit 120. Alternatively, the information on the number of divisions may be sent by email to a device such as a smartphone held by the user. In this case, the image forming apparatus 1 only needs to have an email sending function. Alternatively, the number of divisions may be notified to the user by the number of times a buzzer is output. In this case, the image forming apparatus 1 only needs to have a buzzer. In short, the image forming apparatus 1 only needs to have a notification function to notify the user of the number of divisions before enlarging and dividing the original image and copying and printing it onto a recording medium.

[0031] (effect) Based on the above explanation, the CPU 301 determines the number of divisions required to enlarge and copy the original image onto the recording medium, based on the size of the recording medium. Before copying, the CPU 301 notifies the user of the determined number of divisions. Since the number of divisions notified is determined based on the size of the recording medium, it is possible to notify the user of the exact number of divisions. Therefore, the CPU 301 can avoid reprinting.

[0032] (Second embodiment) In the first embodiment, an example was described in which print icons for each division determined based on the print settings information in Figure 4 are displayed. In the second embodiment, an example is described in which the user intentionally changes the number of divisions. Note that the differences from the first embodiment will be mainly explained, and explanations of configurations similar to the first embodiment will be omitted as appropriate.

[0033] Figure 10 shows an example of switching the display of the print icon according to the second embodiment. In the second embodiment, a use case in which the user changes the division method as a means of intentionally changing the number of divisions is described. A use case in which the user changes the print paper size as a means of intentionally changing the number of divisions is described in the third embodiment. Furthermore, a use case in which the user is prompted to change either the division method or the print paper size is described in the fourth embodiment.

[0034] Figure 10(a) shows an example of window 1000 displaying print settings information. Figure 10(b) shows an example of the settings item window 1100 displayed when the split switching button 1006 in Figure 10(a) is pressed. Figure 10(c) shows an example of the split method setting window 820. Figure 10(d) shows an example of window 1000 after the print settings information has been updated.

[0035] In the example shown in Figure 10(a), print setting information is displayed via a GUI similar to the example in Figure 8, except for the split switching button 1006. For example, the upper left pane displays recording medium information 1001, indicating that the roll paper size is 18-inch roll paper and the paper type is plain paper. The upper right pane displays print count information 1002, indicating that the number of prints is 1. The center pane displays the print icon 1003 and the output size 1004. The print icon 1003 shows an example of splitting a cut-sheet original image into two sections along the short side. The output size 1004 indicates that the LTR cut-sheet original image is enlarged and printed to produce the final ANSI-E output. The lower left pane displays the print setting button 1005. The lower right pane displays the split switching button 1006. When the split switching button 1006 is pressed, the settings item window 1100 shown in Figure 10(b) is displayed. The settings item window 1100 includes a change menu 1103. The change menu 1103 displays a list of switching methods. This list displays options for selecting the division method and changing the number of divisions. When the option for selecting the division method is selected, the division method settings window 820 shown in Figure 10(c) is displayed.

[0036] In the example shown in Figure 10(c), the selectable division methods are displayed as a division method list in the division method settings window 820. The division method list includes options for short-side division and long-side division 825. When item 825 is selected, window 1000 in Figure 10(d) is displayed. The print icon 1003 in Figure 10(d) is changed to a display of the long-side 3-part division in the icon display area 1007 of the central pane.

[0037] Figure 11 is a flowchart illustrating the process of displaying the print icon according to the selection in Figure 10. The process shown in Figure 11 is executed when the window 1000, which displays the print setting information, is operated. Note that some or all of the functions of the steps in Figure 11 may be implemented by hardware such as an ASIC or electronic circuit. The symbol "S" in the description of each process means that it is a step in the flowchart. It is also assumed that the size of the roll paper to be enlarged and the size of the final output are set in advance. Furthermore, the process shown in Figure 11 from S1101 onwards is the same as the process shown in Figure 9, so its explanation is omitted.

[0038] In S1101, the CPU 301 determines whether the split-screen toggle button 1006 is selected or not. If it is determined that the split-screen toggle button 1006 is selected, the CPU 301 proceeds from processing S1101 to processing S901. If it is determined that the split-screen toggle button 1006 is not selected, the CPU 301 continues processing S1101.

[0039] (effect) Based on the above explanation, a split switching button 1006 may be provided to switch between the long side and the short side when performing an enlarged split. If the CPU 301 determines that the split switching button 1006 has been selected, it may execute the process shown in Figure 9. Such a process makes it possible for the user to intentionally change the number of divisions.

[0040] (Third embodiment) In the second embodiment, a use case was described in which the user changes the division method as a means of intentionally changing the number of divisions. In the third embodiment, a use case was described in which the user intentionally changes the number of divisions from 2 to 3. Note that the differences from the first and second embodiments will be mainly explained, and explanations of configurations similar to the first and second embodiments will be omitted as appropriate.

[0041] Figure 12 shows an example of switching the display of the print icon according to the third embodiment. In the third embodiment, a use case is described in which the user changes the print paper size as a means of intentionally changing the number of divisions.

[0042] Figure 12(a) shows an example of window 1000 displaying print settings information. Figure 12(b) shows an example of the settings item window 1100 displayed when the split switching button 1006 in Figure 12(a) is pressed. Figure 12(c) shows an example of the number of divisions change window 1200. Figure 12(d) shows an example of the print paper size setting window 1205. Figure 12(e) shows an example of the number of divisions display window 1400. Figure 12(f) shows an example of window 1000 after the print settings information has been updated.

[0043] In the example shown in Figure 12(a), print setting information is displayed in window 1000 via a GUI similar to that in the example shown in Figure 10(a). For example, the upper left pane displays recording medium information 1001, indicating that the roll paper size is A1 roll paper and the paper type is plain paper. The upper right pane displays print count information 1002, indicating that the number of prints is 1. The center pane displays the print icon 1003 and the output size 1004. The print icon 1003 shows an example of dividing the cut paper original image into two along the long side. The output size 1004 indicates that the LTR cut paper original image is enlarged and printed to produce the final ANSI-E output. The lower left pane displays the print setting button 1005. The lower right pane displays the split switching button 1006. When the split switching button 1006 is pressed, the settings item window 1100 shown in Figure 12(b) is displayed. The settings item window 1100 includes a change menu 1103. The change menu 1103 displays a list of switching methods, similar to Figure 10(b). When the item for changing the number of divisions is selected, the division number change window 1200 shown in Figure 12(c) is displayed.

[0044] In the example shown in Figure 12(c), the item "Select Paper Size" is displayed as an option in the division number change window 1200. When the item "Select Paper Size" is selected, the print paper size setting window 1205 shown in Figure 12(d) is displayed. In the example shown in Figure 12(d), a list of selectable paper sizes is displayed in the print paper size setting window 1205. When a paper size is selected from the list of selectable paper sizes, the division number display window 1400 shown in Figure 12(e) is displayed. For example, if 18-inch roll paper is selected from 18-inch roll paper, 24-inch roll paper, A1-inch roll paper, and A2-inch roll paper, the message "The number of divisions is 3" is displayed in the division number display window 1400. After the division number display window 1400 is displayed, window 1000 shown in Figure 12(f) is displayed. The print icon 1003 in Figure 12(f) is changed to a display showing the long side divided into three sections. Alternatively, instead of displaying the division count window 1400 in Figure 12(e), the division count may be displayed for each paper size in the print paper size setting window 1205 in Figure 12(d).

[0045] Figure 13 is a flowchart illustrating the display process of the print icon according to the selection in Figure 12. The process shown in Figure 13 is executed when the window 1000, which displays the print settings information, is operated. Note that some or all of the functions of the steps in Figure 13 may be implemented by hardware such as an ASIC or electronic circuit. The symbol "S" in the description of each process means that it is a step in the flowchart. It is also assumed that the size of the roll paper to be enlarged and the size of the final output are set in advance.

[0046] In S1301, the CPU 301 determines whether the split-screen toggle button 1006 is selected or not. If it is determined that the split-screen toggle button 1006 is selected, the CPU 301 proceeds to process S1302. If it is determined that the split-screen toggle button 1006 is not selected, the CPU 301 continues the process of S1301. For example, if the split-screen toggle button 1006 of window 1000 in Figure 12(a) is pressed, the settings item window 1100 in Figure 12(b) will be displayed.

[0047] In S1302, the CPU 301 determines whether or not it has received a request to change the number of divisions. If it determines that it has received a request to change the number of divisions, the CPU 301 proceeds to process S1303. If it determines that it has not received a request to change the number of divisions, the CPU 301 continues the process of S1302. For example, if an item to change the number of divisions is selected in the setting item window 1100 in Figure 12(b), the division number change window 1200 in Figure 12(c) is displayed, and the CPU 301 proceeds to the process of selecting the paper size.

[0048] In S1303, the CPU 301 determines whether or not it has received a request to change the paper size. If it determines that it has received a request to change the paper size, the CPU 301 proceeds to process S1304. If it determines that it has not received a request to change the paper size, the CPU 301 continues the process of S1303. For example, if the item "Select paper size" in Figure 12(c) is selected, the print paper size setting window 1205 in Figure 12(d) will be displayed.

[0049] In S1304, the CPU 301 determines whether the print paper size is A2, 17-inch, or 18-inch. If the print paper size is determined to be A2, 17-inch, or 18-inch, the CPU 301 proceeds from processing S1304 to processing S1305. Here, each roll of A2, 17-inch, and 18-inch paper can be divided into two sections if the short side is divided, but if the long side is divided, it must be divided into three sections to maintain the aspect ratio between the original image and the final output. In S1305, the CPU 301 determines whether the division will be along the long side based on the number of divisions and the paper size. If it is determined that the division will be along the long side based on the number of divisions and the paper size, the CPU 301 proceeds from processing S1305 to processing S1306. In S1306, the CPU 301 sets the display setting of the print icon to a three-section icon and proceeds from processing S1306 to S1308. If it is determined that the paper will not be divided along the long side based on the number of divisions and the paper size, the CPU 301 proceeds from processing S1305 to processing S1307.

[0050] Here, if in S1304 it is determined that the print paper size is neither A2, 17-inch, nor 18-inch, the CPU 301 proceeds from processing S1304 to processing S1307. In S1307, the CPU 301 sets the display setting of the print icon to a two-part icon and proceeds from processing S1307 to processing S1308. In S1308, the CPU 301 displays the number of divisions and terminates processing. The number of divisions is displayed using text, for example, as shown in Figure 12(e).

[0051] (effect) Based on the above explanation, if the size of the recording medium is changed, the display of the icon image may be changed accordingly. With this process, the display of the icon image will also change according to the change, making it possible for the user to intentionally change the number of divisions.

[0052] (Fourth embodiment) In the third embodiment, a use case was described in which the user intentionally changes the number of divisions by changing the print paper size and switching from 2 divisions to 3 divisions. In the fourth embodiment, a use case was described in which the user intentionally changes the number of divisions by changing the print paper size and switching from 3 divisions to 2 divisions. The configuration for changing from 3 divisions to 2 divisions can be one in which the division method and the print paper size are changed. Note that the differences from the first to third embodiments will be mainly explained, and explanations of configurations similar to the first to third embodiments will be omitted as appropriate.

[0053] Figure 14 shows an example of switching the display of the print icon according to the fourth embodiment. In the fourth embodiment, a use case is described in which the user intentionally changes the number of divisions from 3 to 2.

[0054] Figure 14(a) shows an example of window 1000 displaying print setting information. Figure 14(b) shows an example of the setting item window 1100 displayed when the split switching button 1006 in Figure 14(a) is pressed. Figure 14(c) shows an example of the setting change guide window 1300. Figure 14(d) shows an example of the setting change window 1305. Figure 14(e) shows an example of the print paper size setting window and the split method setting window. Figure 14(f) shows an example of the number of divisions display window 1400. Figure 14(g) shows an example of window 1000 after the print setting information has been updated.

[0055] In the example shown in Figure 14(a), print setting information is displayed in window 1000 via a GUI similar to that in the example shown in Figure 12(a). For example, the upper left pane displays recording medium information 1001, indicating that the roll paper size is A2 roll paper and the paper type is plain paper. The upper right pane displays print count information 1002, indicating that the number of prints is 1. The center pane displays the print icon 1003 and the output size 1004. The print icon 1003 shows an example of dividing the long side of a cut sheet original into three parts. The output size 1004 indicates that the cut sheet original image from the LTR will be enlarged and printed to produce the final ANSI-E output. The lower left pane displays the print setting button 1005. The lower right pane displays the split switching button 1006. When the split switching button 1006 is pressed, the settings item window 1100 shown in Figure 14(b) is displayed. The settings item window 1100 includes a change menu 1203. The change menu 1203 displays a list of switching methods, similar to that shown in Figure 12(b). When the item for changing the number of divisions is selected, the setting change guide window 1300 shown in Figure 14(c) is displayed, followed by the setting change window 1305 shown in Figure 14(d). The setting change guide window in Figure 14(c) displays the message, "Please change one of the settings." This is because there are multiple setting items required to change the number of divisions. If the item "Select paper size" is selected in the setting change window 1305 in Figure 14(d), the division method setting window, similar to that of the second embodiment, is displayed in the foreground from the window group 1306 in Figure 14(e). On the other hand, if the item "Select division method" is selected in the setting change window 1305 in Figure 14(d), the print paper size setting window, similar to that of the third embodiment, is displayed in the foreground from the window group 1306 in Figure 14(e). Depending on the item selected in the window group 1306 in Figure 14(e), the division count display window 1400 in Figure 14(f) is displayed, followed by the window 1000 in Figure 14(g). In one example in Figure 14(f), "The number of divisions is 2" is displayed, and in one example in Figure 14(g), the print icon 1003, which has been changed to a 2-way division along the long side, is displayed.Furthermore, if long-side division and two-part division are possible, only A1 roll paper or 24-inch roll paper are available; therefore, the GUI should be designed so that other options cannot be selected. In other words, when the paper size and division method are selected, the processing is performed under the constraints of the correlation diagram 700 in Figure 7.

[0056] Figure 15 is a flowchart illustrating the display process of the print icon according to the selection in Figure 14. The process shown in Figure 15 is executed when the window 1000, which displays the print setting information, is operated. Note that some or all of the functions of the steps in Figure 15 may be implemented by hardware such as an ASIC or electronic circuit. The symbol "S" in the description of each process means that it is a step in the flowchart. It is also assumed that the size of the roll paper to be enlarged and the size of the final output are set in advance. Furthermore, the processes S1501 to S1502 in Figure 15 are the same as the processes S1301 to S1302 in Figure 13. The processes S1507 to S1511 in Figure 15 are the same as the processes S1304 to S1308 in Figure 13. The processes S1503 to S1506 in Figure 15 are different from the process S1303 in Figure 13.

[0057] In S1503, the CPU 301 displays a guide. For example, the settings change guide window 1300 shown in Figure 14(c) is displayed. In S1504, the CPU 301 determines whether a paper size has been selected or not. If it is determined that a paper size has been selected, the CPU 301 proceeds from the S1504 process to the S1505 process. For example, in the settings change window 1305 shown in Figure 14(d), the item "Select paper size" is selected, and the paper size is changed. On the other hand, if it is determined that no paper size has been selected, the CPU 301 proceeds from the S1504 process to the S1506 process. For example, in the settings change window 1305 shown in Figure 14(d), the item "Select division method," which is an item other than "Select paper size," is selected, and the division method is changed.

[0058] (effect) Based on the above explanation, the CPU 301 may re-notify the number of divisions in accordance with the change in the size of the recording medium. Furthermore, the CPU 301 may re-notify the number of divisions in accordance with the change in either the long side or the short side. These processes improve usability because the number of divisions is re-notified in accordance with changes in the size or division method of the recording medium.

[0059] <Other Embodiments> Although various examples and embodiments of this disclosure have been described above, the spirit and scope of this disclosure are not limited to the specific descriptions herein. This disclosure is not limited to the embodiments described above, and various modifications may be made. Furthermore, this disclosure may combine some of the embodiments described above as appropriate.

[0060] (Variation 1) For example, we have described an example where a roll of paper is divided as a recording medium, but the system is not limited to this. For example, a cut sheet of paper may be divided, and then the printout may be enlarged to a size larger than the size of the divided cut sheet.

[0061] (Modification 2) Furthermore, while we have described an example where the original paper size is LTR (letter size; 215.9 × 279.4 mm) and the enlarged paper size is ANSI-E (864 × 1118 mm), we are not limited to this example. For instance, the original paper size may be A4 (210 × 297 mm) and the enlarged paper size may be A0 (841 × 1189 mm).

[0062] (Variation 3) Furthermore, while the first to fourth embodiments described use cases assuming that print setting information has been selected in advance, there is no need to limit the process to this. The selection may be made while the process is running. Figure 16 is a flowchart illustrating the display process of a print icon according to a modified example. Note that the processes S901 to S905 in Figure 16 are the same as the processes S901 to S905 in Figure 9, so their explanation will be omitted.

[0063] In S1601, the CPU 301 determines whether a print paper size has been selected. If it is determined that a print paper size has been selected, the CPU 301 proceeds from processing S1601 to processing S1602. The print paper size is the size of the recording medium to which the output will be printed when the original image is enlarged, divided, and copied onto the recording medium. For example, roll paper can be used as print paper. If it is determined that a print paper size has not been selected, the CPU 301 continues processing S1601. In S1602, the CPU 301 determines whether an enlargement size has been selected. If it is determined that an enlargement size has been selected, the CPU 301 proceeds from processing S1602 to processing S901. The enlargement size is the size of the final output. For example, an A0 final output can be obtained by scanning an A4 cut sheet original, enlarging and dividing the original image, copying it onto A1 roll paper, and then cutting and pasting the copied pieces. On the other hand, if it is determined that an enlargement size has not been selected, the CPU 301 continues processing S1602.

[0064] Based on the above explanation, even if print settings information is not prepared in advance, it is possible to improve usability by setting the print settings information as needed.

[0065] (Modification 4) Although an example of notifying the number of divisions has been described according to the correlation diagram 700 in Figure 7, the CPU is not limited to this. The size of the original image and whether the divided images obtained by enlarging and dividing the original image fit within the width of the storage medium may be determined each time. For example, the CPU 301 may increase the number of divisions if the divided images obtained by enlarging and dividing the original image do not fit within the width of the recording medium. Alternatively, the CPU 301 may decide to set the number of divisions to 2 if the divided images obtained by enlarging and dividing the original image fit within the width of the recording medium. Alternatively, the CPU 301 may decide to set the number of divisions to 3 if the divided images obtained by enlarging and dividing the original image do not fit within the width of the recording medium. Alternatively, the CPU 301 may determine that the divided images do not fit within the width of the recording medium if the aspect ratio of the final result obtained by pasting multiple copied images onto the recording medium is different from the aspect ratio of the original image.

[0066] (Variation 5) Furthermore, while we have described an example of intuitively notifying the number of divisions using the print icon 803 or print icon 1003, or an example of notifying the number of divisions in text as shown in Figure 12(e), we are not limited to these. For example, the number of divisions may be displayed in the central pane of window 1000. By displaying the number of divisions in window 1000 and notifying the user of the number of divisions, the CPU 301 can accept an instruction to perform copy printing when the user presses the start button 210C on the operation unit 120. In other words, the CPU 301 may notify the number of divisions on the screen where the print settings information is displayed. Alternatively, the CPU 301 may accept an instruction to perform copy printing when the start button 210C is pressed while the number of divisions is displayed on the screen where the print settings information is displayed.

[0067] The present invention can also be realized by supplying a program that implements one or more of the functions of the above-described embodiments to a system or device via a network or storage medium, and by having one or more processors in the computer of that system or device read and execute the program. It can also be realized by a circuit (e.g., an ASIC) that implements one or more functions. Furthermore, the program may be recorded on a recording medium readable by a computer and provided.
