  The printer 10 includes a CPU 11 and a ROM 12 that function as a control unit according to the present invention, a RAM 13 and an NVRAM 14 that function as a storage unit according to the present invention, and a network interface 15. The CPU 11 executes various control programs and image data processing programs (see FIG. 2) stored in the ROM 12, and stores the execution results in the RAM 13 or the NVRAM 14 which is a non-volatile memory. To control. The ROM 12 stores an image data processing program shown in FIG. 2, a control program for executing various operations of the printer 10, a control table, and the like. The NVRAM 14 stores user settings for various functions in the printer 10. The user setting includes a margin width in “poster printing” to be described later, and is set to a user-desired setting value by a user operation using the operation unit 18. The network interface 15 realizes bidirectional data communication between the computers 20 and the like connected via a communication line 30 such as a LAN.

  The printer 10 includes a printing unit 16, a display unit 17, and an operation unit 18. The printing unit 16 forms a print image on a recording sheet, a plastic sheet, or the like using one or a plurality of colorants (toner, ink, or the like) by, for example, an electrophotographic method or an inkjet method. The display unit 17 includes a liquid crystal display, a lamp, and the like, and is configured to be able to display various setting screens and operation states of the apparatus. The operation unit 18 includes a plurality of buttons and is used when a user inputs various instructions.

  On the other hand, the computer 20 includes a CPU 21, a ROM 22, a RAM 23, a hard disk drive 24, an operation unit 25 including a keyboard and pointing device, a display unit 26 including a display, a network interface 27 connected to the communication line 30, and the like. The hard disk drive 24 stores various control programs such as application software for creating the print image data 50 and a printer driver for controlling the operation of the printer 10.

  In the first embodiment, the user can make a setting for instructing so-called “poster printing” when creating the print image data 50 using the computer 20. In the “poster printing”, in order to obtain a printed matter having a large output size (for example, a poster or a banner), a print image 51 related to one print image data 50 is divided into a plurality of divided images corresponding to the size of the recording paper. This means that the output is divided into two. The recording sheets on which the plurality of divided images generated by the “poster printing” are printed are connected together in an appropriate arrangement, thereby providing a poster or banner desired by the user.

  In the first embodiment, the image data processing program shown in FIG. 2 is executed by the CPU 11 of the printer 10 when the print image data 50 generated by the computer 20 is transmitted to the printer 10 via the communication line 30. Executed.

  The print image data 50 in this case only needs to include an instruction to execute “poster print” and one print image 51. The print image 51 itself in the print image data 50 does not need to have a large size from the beginning. For example, the print image 51 may be enlarged by enlarging on the printer 10 side. In the following description, as a specific example, the print image data 50 relating to the A3 size print image 51 is “poster printed”, and printed on two sheets of A4 size recording paper. explain.

  When the execution of the image data processing program according to the first embodiment is started, the CPU 11 of the printer 10 first receives print image data 50 that is a target of “poster printing” from the computer 20 (S1). Thereafter, the CPU 11 stores the received print image data 50 in the RAM 13, and proceeds to S2.

  In S <b> 2, the CPU 11 sets a plurality of divided areas for the print image 51 of the received print image data 50. Specifically, the CPU 11 sets the first divided area 70A and the second divided area 70B corresponding to the A4 size side by side with respect to the A3 size print image 51 (see the left diagrams in FIGS. 3 and 4). When the setting of the plurality of divided areas is completed, the CPU 11 shifts the process to S3.

  When the process proceeds to S3, the CPU 11 executes the target image position specifying process, and based on the print image 51 of the received print image data 50 and the plurality of divided areas set in the print image 51 in S2, the print image 51 is printed. The position of the target image 60 is specified, and the position of the target image 60 in each divided area constituting the divided boundary line 71 is specified. Here, the target image 60 is a portion of the print image 51 of the print image data 50 where an image is recorded on a recording sheet or the like using one or more colorants (toner, ink, etc.). Yes, it means the part that is the target of image recording. That is, a portion of the print image 51 excluding the target image 60 becomes a blank portion where no image is formed with one or a plurality of colorants. When the target image position specifying process (S3) ends, the CPU 11 shifts the process to S4.

  In S4, the CPU 11 determines whether or not the target image 60 is located on the division boundary 71 based on the plurality of divided regions set in S2 and the processing result of the target image position specifying process (S3). To do. Here, the division boundary line 71 means a boundary between a plurality of adjacent divided areas, and is set as a boundary between the first divided area 70A and the second divided area 70B as shown in FIG. When the target image 60 is on the division boundary line 71 (S4: YES), the CPU 11 shifts the process to S5. On the other hand, when the target image 60 is not on the division boundary line 71 (S4: NO), the CPU 11 shifts the process to S6.

  In S <b> 5, the CPU 11 executes a normal margin setting process and performs settings related to the margin 80 arranged in the divided image obtained by dividing the print image 51 into a plurality of divided regions. Specifically, the CPU 11 sets a margin width W of a margin 80 extending along the boundary based on the division boundary line 71 among the boundaries of one division image divided from the print image 51 based on one division area. To do. As illustrated in FIG. 3, when generating the first divided image 76A and the second divided image 76B obtained by dividing the print image 51 based on the first divided region 70A and the second divided region 70B, the CPU 11 A predetermined value (excluding “0”) is set for the margin width W for the margin 80 arranged along the lower edge of the divided image 76A. When the normal margin setting process (S5) ends, the CPU 11 shifts the process to S7.

  In step S6, the CPU 11 executes a marginless setting process, and sets the margin 80 arranged in the divided image obtained by dividing the print image 51 into each of a plurality of divided areas. Specifically, the CPU 11 sets the margin width of the margin 80 extending along the boundary based on the division boundary line 71 among the boundaries of one division image divided from the print image 51 based on one division area to “0”. To "". As shown in FIG. 4, when generating the first divided image 76A and the second divided image 76B obtained by dividing the print image 51 based on the first divided region 70A and the second divided region 70B, the CPU 11 By setting the margin width W of the margin 80 arranged along the lower edge of the divided image 76A to “0”, the margin 80 is set to “none”. When the blank space setting process (S6) ends, the CPU 11 shifts the process to S7.

  In S7, the CPU 11 determines whether the value of the margin width W set by the normal margin setting process (S5) or the no margin setting process (S6) is different from the user set value of the margin width W stored in the NVRAM 14. Judge whether or not. When the value of the margin width W is different from the user set value (S7: YES), the CPU 11 shifts the process to S8. On the other hand, when the value of the margin width W matches the user setting value (S7: NO), the CPU 11 shifts the process to S11.

  In S <b> 8, the CPU 11 executes a confirmation display process and displays a change confirmation window 85 on the display unit 17. As shown in FIG. 5, the change confirmation window 85 includes “printing related to the divided image with a margin width W different from the user setting” and “print output relating to the divided image with the margin width W different from the user setting”. Message to ask whether or not to allow the user to continue. When the confirmation display process (S8) ends, the CPU 11 shifts the process to S9.

  In step S9, the CPU 11 determines whether a change permission operation has been performed. In the first embodiment, the change-permitted operation refers to an operation of selecting the “YES” button of the change confirmation window 85 shown in FIG. 5 by operating the operation unit 18, and to a divided image with a margin width W different from the user setting. This means that the continuation of the print output is allowed. When the change permissible operation is performed (S9: YES), the CPU 11 shifts the process to S11. On the other hand, when the change permissible operation has not been performed (S9: NO), the CPU 11 shifts the process to S10. The case where the change-permitted operation is not performed means a case where an operation for selecting the “NO” button of the change confirmation window 85 shown in FIG.

  In S10, the CPU 11 executes a margin setting process based on the selection operation performed on the “NO” button in the change confirmation window 85 shown in FIG. 5 (S9: NO). In this case, the CPU 11 reads the user setting value of the margin width W from the NVRAM 14 and arranges the margin 80 of the margin width W according to the user setting value along the boundary based on the division boundary line 71. In this margin setting process (S10), the CPU 11 determines that the target image 60 does not exist on the division boundary line 71 (S5: NO) and the margin 80 based on the user setting value and the divided image. A boundary indicating image 90 is added to the boundary portion between the two (ie, the boundary of the divided image based on the divided boundary line 71) (see FIG. 6). When the margin setting process (S10) ends, the CPU 11 proceeds to S11.

  In S11, the CPU 11 selects the print image data 50 received in S1, the plurality of divided areas (for example, the first divided area 70A and the second divided area 70B) set in S2, and any one of S5, S6, and S10. A plurality of pieces of divided image data are generated based on the margin width W set by. As shown in FIGS. 3 and 4, the CPU 11 first divides the print image 51 related to the print image data 50 based on the first divided area 70 </ b> A and the second divided area 70 </ b> B, so that the first divided image 76 </ b> A is obtained. The second divided image 76B is specified. Then, for each of the first divided image 76A and the second divided image 76B, the CPU 11 sets the margin 80 having the margin width W set by any one of S5, S6, and S10 along the boundary corresponding to the division boundary line 71. The first divided image data 75A and the second divided image data 75B are generated respectively. At this time, the CPU 11 performs image processing such as enlargement / reduction / movement of each divided image (first divided image 76A, second divided image 76B) as necessary, and positions of the divided images according to the presence or absence of the margin 80. Variations may be adjusted. Thereafter, the CPU 11 stores the first divided image data and the second divided image data in the RAM 13, and proceeds to S12.

  In step S12, the CPU 11 executes print execution processing to read the generated divided image data from the RAM 13 and print them on the recording paper by the printing unit 16, respectively. At this time, since the margin 80 based on the margin width W is formed in each divided image data, as shown in the right diagrams in FIGS. 3 and 4, the user uses the margin 80 to divide each divided image data. By connecting the recording paper on which the image is printed, a large-sized printed matter from which the print image 51 is output can be configured.

  As described above, according to the printer 10 according to the first embodiment, the CPU 11 executes the image data processing program (see FIG. 2), whereby the first set for the print image 51 of the print image data 50. Based on the one divided area 70A and the second divided area 70B, first divided image data 75A and second divided image data 75B relating to a divided image obtained by dividing the print image 51 into a plurality of divided areas may be generated. it can.

  Then, according to the printer 10, by executing the processes of S <b> 3 to S <b> 6, an appropriate margin width W is set based on the position of the target image 60 with reference to the boundary of the divided image corresponding to the divided boundary line 71. The divided image data in which the margin 80 is arranged along the division boundary line 71 can be generated. Therefore, according to the printer 10, the output result of a plurality of divided images (first divided image 76A and second divided image 76B) having an appropriate margin width W based on the plurality of divided image data generated in S11. Can be provided. As shown in the right diagrams of FIGS. 3 and 4, in the output result of each divided image, a margin 80 having an appropriate margin width W according to the position of the target image 60 is formed. For example, the margin 80 can be used to connect the output results of the divided images, and even when the print image 51 is reconstructed, deterioration in appearance can be suppressed.

  As shown in FIG. 3, according to the printer 10, when the position of the target image 60 is specified to be on the division boundary line 71 (S <b> 4: YES), the printer 10 extends along the division boundary line 71. The value of the margin width W of the margin 80 is set to a value larger than 0 (S5). Thereby, according to the printer 10, when the output results of the respective divided images (the first divided image 76A and the second divided image 76B) are pasted using the margin 80, the first divided image 76A and the second divided image 76A are combined. A gap between the divided images 76B can be eliminated, and even when the print image 51 is reconstructed, deterioration in appearance can be suppressed. If the margin width W is set to 0 in this case, two recording sheets are used when the recording sheet on which the first divided image 76A is formed and the recording sheet on which the second divided image 76B is formed. There will be a little gap in between. From the gap between the two recording sheets, the pattern and color behind the recording sheet (for example, the pattern and color of the wall on which the recording sheet is posted) can be seen, and the print image 51 is divided. Therefore, the appearance of the print image 51 as a whole is deteriorated.

  As shown in FIG. 4, according to the printer 10, when it is determined that the position of the target image 60 is not on the division boundary line 71 (S <b> 4: NO), the margin extending along the division boundary line 71. The margin width W of 80 is set to 0 (S6). Thus, according to the printer 10, when the output results of the respective divided images (first divided image 76A and second divided image 76B) are pasted together, it is possible to accurately align the boundaries of the divided images. Even if the print image 51 is reconstructed, it is possible to suppress a decrease in appearance. In this case, if the margin width W is set to a value larger than 0, the blank image of the first divided image 76A and the margin 80 are continuous, so the boundary between the first divided image 76A and the margin 80 is I don't know. Therefore, by adding the boundary indicating image 90, it is difficult to accurately align the boundary of the divided image unless the boundary position between the divided image and the margin is suggested.

Further, according to the printer 10, when it is determined that the value of the margin width W set in the normal margin setting process (S5) or the no margin setting process (S6) is different from the user setting value of the margin width W. The change confirmation window 85 is displayed on the display unit 17 (S7: YES).
Thus, according to the printer 10, when each divided image data is generated with a margin width W different from the user setting value of the margin width W stored in the NVRAM 14, the change confirmation window 85 prompts the user in advance. Confirmation can be requested and the intention of the user can be reflected.

  Furthermore, according to the printer 10, it is determined that the generation of the margin 80 having a margin width W different from the user setting value is not permitted (S9: NO), and the target image 60 does not exist on the division boundary line 71. In the case (S4: NO), in the margin setting process (S10), the boundary instruction image 90 indicating the boundary between the divided image and the margin 80 can be added to the divided image data (see FIG. 6). As a result, according to the printer 10, as shown in FIG. 6, even when the boundary between the divided image and the margin 80 is difficult to understand, the boundary position of the divided image is clearly grasped by the boundary instruction image 90. can do. Therefore, when the output medium of each divided image is pasted, it can be accurately positioned with respect to the boundary of the divided image. Therefore, according to the printer 10, it is possible to suppress deterioration in appearance when the print image 51 is reconstructed. can do.

(Second Embodiment)
Next, an embodiment (second embodiment) different from the above-described first embodiment will be described in detail with reference to the drawings. The printer 10 and the computer 20 according to the second embodiment have the same basic configuration as the printer 10 and the computer 20 according to the first embodiment, and the processing contents of the image data processing program are different. Accordingly, the description of the same configuration and processing contents as in the first embodiment is omitted.

  As shown in FIG. 7, in the image data processing program according to the second embodiment, the CPU 11 first receives print image data 50 from the computer 20 via the communication line 30 (S21). The process according to S21 is the same process as S1 in the first embodiment. Thereafter, the CPU 11 provisionally sets a plurality of divided areas (first divided area 70A and second divided area 70B) for the print image 51 of the print image data 50 (S22). Thereafter, the CPU 11 shifts the process to S23.

  In step S23, the CPU 11 sets the margin width W of the margin 80 arranged along the division boundary 71 set in the print image 51 of the print image data 50 to the user setting of the margin width W stored in the NVRAM 14. Set based on the value. When the setting of the margin width W is completed, the CPU 11 shifts the process to S24.

  In S24, the CPU 11 executes target image position specifying processing. In the target image position specifying process (S24), the CPU 11 performs a print image 51 of the received print image data 50 and a plurality of divisions temporarily set to the print image 51 in S2 as in S3 according to the first embodiment. Based on the area, the position of the target image 60 in the print image 51 is specified, and the position of the target image 60 in each divided area constituting the divided boundary line 71 is specified. Thereafter, the CPU 11 shifts the processing to S25.

  In S25, the CPU 11 determines whether or not the target image 60 is located on the division boundary line 71 based on the plurality of divided regions temporarily set in S22 and the processing result of the target image position specifying process (S3). To do. When the target image 60 is on the division boundary line 71 (S25: YES), the CPU 11 shifts the process to the normal margin setting process (S26). The processing content of the normal margin setting process (S26) is the same as that of the first embodiment, and the margin width W of the margin 80 extending along the boundary based on the division boundary line 71 is set (see FIG. 3). Thereafter, the CPU 11 shifts the process to S30. On the other hand, when the target image 60 is not on the division boundary line 71 (S25: NO), the CPU 11 shifts the process to S27.

  In S27, the CPU 11 determines whether the edge distance is smaller than a predetermined value. Here, the edge distance means the shortest distance between the boundary of the divided image and the target image 60 included in the divided image, and as shown in FIGS. 8 and 9, the edge in the first divided image 76A. The distance is referred to as “first edge distance LA”, and the edge distance in the second divided image 76B is referred to as “second edge distance LB”. Further, the predetermined value means a distance that is displaced due to a user's hand shake or the like when the recording sheets on which the divided images are printed are pasted together. For example, the predetermined value is a distance that is 1 mm when output to the recording sheet. .

  When the edge distance is smaller than the predetermined value (S27: YES), the CPU 11 shifts the process to S28. On the other hand, when the edge distance is equal to or greater than the predetermined value (S27: NO), the CPU 11 proceeds to the normal margin setting process (S26), and the margin width W of the margin 80 extending along the boundary based on the divided boundary line 71. Is set (see FIG. 3). Thereafter, the CPU 11 shifts the process to S30.

  In S28, the CPU 11 executes a margin reduction setting process. In this margin reduction setting process (S28), the CPU 11 reduces the margin width W of the margin 80 arranged along the dividing boundary 71 by a predetermined amount of correction width D. Thereafter, the CPU 11 shifts the process to S29.

  In S29, the CPU 11 executes the divided image correction process, and reduces the margin width W of the margin 80 by the margin reduction setting process (S28). to correct. After completing the divided image correction process (S29), the CPU 11 shifts the process to S30.

  Here, processing contents of the margin reduction setting process (S28) and the divided image correction process (S29) will be described with specific examples with reference to FIGS. As a specific example, one print image 51 is divided into a first divided image 76A and a second divided image 76B based on the first divided region 70A and the second divided region 70B.

  As shown in FIG. 8, before the processing of the margin reduction setting process (S28) and the divided image correction process (S29), the edge distance in the first divided image 76A is defined as “first edge distance LA”, and the margin width of the margin 80 is set. Is “margin width W”. Similarly, the edge distance of the second divided image 76B at this time is defined as “second edge distance LB”. After the margin reduction setting process (S28) and the divided image correction process (S29), the edge distance in the first divided image 76A is set to “first edge distance LA ′”, and the margin width of the margin 80 is set to “margin width”. W ′ ”. Similarly, the edge distance of the second divided image 76B after this processing is defined as “second edge distance LB ′”.

  As shown in FIG. 9, when the margin reduction setting process (S28) is executed, the margin 80 in the first divided image 76A is reduced by the correction width D from the margin width W before processing, and becomes the margin width W ′. . In this case, in the divided image correction process (S29), for the first divided image 76A, the CPU 11 has blank data corresponding to the correction width D along the divided boundary line 71 in the inner portion of the first divided image 76A. Is added. Accordingly, the first edge distance LA ′ after the divided image correction process (S29) is a distance obtained by adding the correction width D to the first edge distance LA before the process (see FIG. 9).

  On the other hand, in the second divided image 76B adjacent to the first divided image 76A via the divided boundary line 71, the CPU 11 determines the target image 60 included in the second divided image 76B in the divided image correction process (S29). Then, it is moved closer to the division boundary 71 by the correction width D. Thus, the second edge distance LB ′ after the divided image correction process (S29) is a distance obtained by reducing the correction width D from the second edge distance LB before the process (see FIG. 9).

  With reference to FIG. 7 again, processing contents after S30 of the image data processing program according to the second embodiment will be described. When the process proceeds to S30, the CPU 11 determines that the print image data 50 received in S21 and a plurality of divided areas set in the print image 51 of the print image data 50 (for example, the first divided area 70A and the second divided area). 70B) and the processing result (the processing result of S26 or S28 to S29) related to the margin 80 and the like, a plurality of pieces of divided image data are generated. Thereafter, the CPU 11 stores the first divided image data and the second divided image data in the RAM 13, and the process proceeds to S32.

  In S <b> 31, the CPU 11 reads out each generated divided image data from the RAM 13 by executing a print execution process, and prints it on a recording sheet by the printing unit 16. At this time, since the margin 80 based on the margin width W is formed in each divided image data as shown in the right diagrams in FIGS. 3 and 4 and FIG. 9, the user can use the margin 80 for each divided image. By connecting the recording sheets on which the divided images related to the data are printed, a large-sized printed matter from which the print image 51 is output can be configured.

  As described above, according to the printer 10 according to the second embodiment, by executing the margin reduction setting process (S28) and the divided image correction process (S29), in the divided image data in which the margin 80 is set, The distance between the boundary of the divided images and the target image 60 (for example, the first edge distance LA ′) is a predetermined value or more. Therefore, according to the printer 10 according to the second embodiment, when the recording sheet of the other divided image is pasted on the margin 80 of the recording sheet of one divided image, the one divided image becomes the other divided image. Can be prevented from being hidden by the recording paper. Thereby, according to the printer 10, even when the recording paper is pasted and the print image 51 is reconstructed, a part of the print image 51 is not lost, and deterioration in appearance is suppressed. Can do.

  Further, according to the printer 10 according to the second embodiment, the margin width W of the margin 80 is reduced by the correction width D by the margin reduction setting process (S28), and is adjacent via the division boundary line 71. The contents of the first divided image 76A and the second divided image 76B are corrected by the divided image correction process (S29) (see FIGS. 8 and 9). In this divided image correction process (S29), the positional relationship between the target image 60 in the first divided image 76A and the target image 60 in the second divided image 76B is maintained in the same manner as before the margin reduction setting process (S28). be able to. That is, according to the printer 10, it is possible to prevent the appearance from being deteriorated when the print image 51 is reconstructed by pasting the recording sheets by reducing the margin width W accompanying the margin reduction setting process (S 28).
