The print data for printing the constituent parts of the predetermined figure can be created at the end of each print medium so that the figure is formed. As a result, when a plurality of print media on which printing has been performed are overlapped in page order, the right side, left side, plane side, and bottom side of the bundle of sheets when the cover side is the front side (in the present invention, “ A predetermined figure is formed on at least one of the end aggregate surfaces “). Therefore, the viewer of the printed matter can easily confirm that a part of the printing medium is removed or lost only by confirming whether or not the graphic is correctly formed. In addition, since it is difficult to accurately copy up to the printing position of the graphic component, confirm whether the graphic is correctly formed by checking whether the graphic is correctly formed. It is possible to determine whether the copy is a duplicate. Also, it is possible to create print data that forms a management pattern with a different pattern every time print data is created. Therefore, information can be managed by associating the person who instructed printing on the printing medium, the printing time, the printing location, and the like with the management figure. Each time print data is created, at least one of the width of the component in the direction along the edge of the print medium, the print position of the component on the first page, and the print position of the component on the last page Different print data can be created. Therefore, management figures can be specified based on these and information can be managed.
According to the print data creation device of the third aspect of the present invention, the plurality of print media are stacked in the page order, whereby the end gathering surface formed by gathering the end portions of the print media is predetermined. The print data for printing the constituent parts of the predetermined figure can be created at the end of each print medium so that the figure is formed. As a result, when a plurality of print media on which printing has been performed are overlapped in page order, the right side, left side, plane side, and bottom side of the bundle of sheets when the cover side is the front side (in the present invention, “ A predetermined figure is formed on at least one of the end aggregate surfaces “). Therefore, the viewer of the printed matter can easily confirm that a part of the printing medium is removed or lost only by confirming whether or not the graphic is correctly formed. In addition, since it is difficult to accurately copy up to the printing position of the graphic component, confirm whether the graphic is correctly formed by checking whether the graphic is correctly formed. It is possible to determine whether the copy is a duplicate. Further, the print data creation device does not create print data for forming a predetermined figure on the end aggregate surface unless the image data acquired by the image data acquisition means is image data of confidential information. . Therefore, it is possible to prevent unnecessary processing from being performed, and it is possible to form a predetermined graphic on the end surface only when it is necessary to check whether the printing medium is removed or to manage information.

In other words, on the end gathering surface, the constituent parts are successively arranged in a certain direction to form a sampling confirmation figure. As a result, if a part of the plurality of printing media is extracted, lost, or not overlapped in the page order, the ends of the constituent parts of the sampling confirmation graphic do not match each other. Therefore, the viewer of the printed matter can easily confirm that there is no error in the extraction or loss of the printing medium and the page order simply by confirming that the ends of the constituent parts of the sampling confirmation figure are coincident with each other. be able to.

In addition to the effect of the invention described in claim 4 , the print data creation device according to claim 5 of the present invention has a width in the direction along the end of each constituent part constituting the sampling confirmation graphic. Is divided by the number of printed sheets. And the extraction confirmation figure formed in an edge part gathering surface turns into a straight line extended on the diagonal of the edge part gathering surface used as a rectangle. Therefore, the viewer of the printed matter can easily recognize that the first page or the last page is missing unless a straight line is applied to the corners of the end gathering surfaces. Also, if there is straight line distortion or unevenness, you can immediately notice that there is an abnormality such as missing page or duplication, so it is easier than when the drawing confirmation figure is another figure. You can notice abnormalities.

However, the printing apparatus 1 may be configured to receive image data in a data format necessary for printing and create only print data for forming the management graphic 30 and the sampling confirmation graphic 40.

  Next, the RAM 12 will be described. As shown in FIG. 1, the RAM 12 is provided with at least a received image data storage area 121 and a created print data storage area 122. In the received image data storage area 121, image data received from another device such as the computer apparatus 2 is temporarily stored. The created print data storage area 122 stores print data created based on the received image data.

  Next, details of the received image data storage area 121 of the RAM 12 will be described. As described above, the image data received from the other device by the printing apparatus 1 according to the present embodiment includes, in addition to the content of information including images and characters, an ID for identifying the transmission source device, the number of printed sheets, and paper. Data indicating the size and whether the content of the information is confidential information is included. As shown in FIG. 2, the received image data storage area 121 of the RAM 12 includes a transmission source ID storage area 1211, a content storage area 1212, a print number storage area 1213, a paper size storage area 1214, and confidentiality.

In the example illustrated in FIG. 2, the ID of the device that is the transmission source of the image data is “g7h8”, the number of printed sheets is 20, and the sheet size is A4 size. In the confidentiality storage area 1215, “1” indicating that the information included in the received image data is confidential information is stored.

  Next, the HDD 13 will be described. As shown in FIG. 1, the HDD 13 is provided with at least a management graphic pattern data storage area 131. As shown in FIG. 3, in the management graphic pattern data storage area 131, a pattern of management graphic 30 (see FIG. 4) for enabling management of information printed on printing paper (hereinafter referred to as “management graphic pattern”). Is stored in association with the image data transmission source and the printing date and time. Specifically, as a management graphic pattern, a transmission source ID for identifying a transmission source device, a printing date and time, the number of prints “P”, and values “X, Y, Z” used when creating the management graphic. The line width “D” of the management graphic 30, the coordinates indicating the printing position of the component 31 (see FIG. 4) of the management graphic 30 on the first page, and the printing of the component 32 (see FIG. 4) on the last page. The coordinates indicating the position are stored.

  Next, the management graphic 30 and the sampling confirmation graphic 40 will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of the printed matter 21 in which the management graphic 30 is formed on the first end aggregate surface 23 and the sampling confirmation graphic 40 is formed on the second end aggregate surface 24.

  The management graphic 30 is a graphic for enabling management of information printed on each printing paper constituting the printed matter 21. In the present embodiment, a plurality of printing sheets are stacked in page order, whereby a management graphic 30 is formed on a straight line on the first end portion collecting surface 23 on the right side when the cover 22 is the front side. The The print data for forming the management graphic 30 includes the management graphic every time printing is performed based on the three values “X, Y, Z” determined by the date, hour, and minute of the printing date and the number of printed sheets. Created with different patterns. That is, the management graphic 30 has at least one of the line width D, the print position of the component part 31 on the first page, the print position of the component part 32 on the last page, and the number of component parts determined by the number of prints P. It is created differently from the management figure of other printed matter that has already been printed. The management graphic pattern is stored in the management graphic pattern data storage area 131 (see FIG. 3) in association with the image data transmission source and the printing date and time. Therefore, the management graphic 30 can specify the device that transmitted the image data to the printing apparatus 1 and the date and time when printing was executed. Further, by storing each device in association with the user of the device, the user who has executed printing can be specified. Therefore, management of information printed on the printed matter 21, that is, management of the user who executed printing and the printing date and time can be easily performed.

  The sampling confirmation graphic 40 is a graphic for facilitating the confirmation of sampling or loss of printing paper. In the present embodiment, a plurality of printed printing sheets are overlapped in page order, so that a sampling confirmation graphic 40 is placed on a diagonal line of the second end aggregate surface 24 that is a flat surface when the cover 22 is the front side. Is formed. As for the constituent parts of each printing paper constituting the sampling confirmation figure 40, the left end coincides with the right end of the constituent part of the previous page, and the right end part is the left side of the constituent part of the next page. Is printed at a position that coincides with the edge of the. Furthermore, the widths in the left-right direction of each component are all equal. As a result, if some of the plurality of printing papers are extracted, lost, or not overlapped in page order, the ends of the constituent parts of the sampling confirmation graphic 40 do not match. Further, when the printed matter 21 is duplicated by copying, it is impossible to accurately copy to the printing position of the constituent part, so that the sampling confirmation figure 40 is not formed straight on the diagonal line. Accordingly, it is possible to easily confirm that the printing paper has been removed, lost, page order error, duplication by copying, and the like by using the extraction confirmation graphic 40.

  Next, the operation of the printing apparatus 1 configured as described above will be described with reference to FIGS. FIG. 5 is a flowchart of main processing performed in the printing apparatus 1, FIG. 6 is a flowchart of management graphic data creation processing executed in the main processing, and FIG. 7 is a sampling confirmation graphic executed in the main processing. It is a flowchart of a data creation process. In the printing apparatus 1, when the power is turned on, the program stored in the ROM 11 is read out and started up in the RAM 12, and the main process shown in FIG. 5 is executed by the CPU 10.

  As shown in FIG. 5, when the main process is started, it is first determined whether image data has been received (S1). The printing apparatus 1 according to the present embodiment is connected to a computer device 2 (see FIG. 1) or a device such as a portable terminal that displays information via an external communication I / F 19 (see FIG. 1). The image data can be received. If it has not been received (S1: NO), it is determined whether or not an instruction to turn off the power by operating the power switch 14 has been issued (S10).

  On the other hand, when image data is received from another device (S1: YES), the received image data is stored in the received image data storage area 121 (see FIG. 2) of the RAM 12 (S2). Then, based on the value of the confidentiality storage area 1215 in the received image data storage area 121, it is determined whether or not the received image data is image data of confidential information (S3). If “0” indicating that it is not confidential information is stored and it is determined that the received image data is not confidential information image data (S3: NO), the management graphic 30 and the sampling confirmation graphic 40 are formed. The print data for printing is not created, but only the print data for printing the contents of the information is created (S8), the printing process is performed (S9), and the process proceeds to determining whether the power is turned off. (S10).

  If “1” indicating confidential information is stored in the confidentiality storage area 1215 and it is determined that the received information is confidential information (S3: YES), the number of printed sheets is plural. It is determined whether or not there is (S4). In the printing apparatus according to the present embodiment, a figure is formed by using the end gathering surfaces 23 and 24 (see FIG. 4) formed by overlapping a plurality of printing sheets. Accordingly, when it is stored in the print number storage area 1213 of the received image data storage area 121 that the number of prints is one (S4: NO), only print data for printing the contents of information is stored. It is created as it is (S8). If the received image data is image data of confidential information (S3: YES) and the number of printed sheets is plural (S4: YES), management graphic data creation processing is performed (S5).

  As shown in FIG. 6, in the management graphic data creation process, first, the current date (A), hour (B), and minute (C) counted by the counter 18 (see FIG. 1) are read (S11). . For example, if the current date and time is 20:50 on November 25, “25” indicating the day is A, “20” indicating the hour is B, and “50” indicating the minute is C. Read out. Next, the print number P is read from the print number storage area 1213 (see FIG. 2) (S12). Then, based on the paper size stored in the paper size storage area 1214 (see FIG. 2), the vertical width H of the printing paper is read (S13). Specifically, the vertical width H and the horizontal width L of the printing paper are stored in the ROM 11 according to each paper size. Here, the vertical width H according to the paper size is read from the ROM 11.

  Next, an x coordinate (see FIG. 4) is set in which the upper right end of the printing paper is the origin O and the lower side is positive (see FIG. 4). The length per unit of the x coordinate varies depending on the vertical width H read based on the paper size, and is “H / 60 (mm)”. Therefore, the position where the x coordinate is 60 is the lower right end of the printing paper.

  Next, X, Y, and Z values that are values for determining the management graphic pattern are determined. First, it is determined whether or not there is N satisfying “3N = A”, that is, whether or not the value of A that has already been read is a multiple of 3 (S15). If N satisfying this condition exists (S15: YES), “X = A, Y = B, Z = C” is set (S16), and the process proceeds to S20. Further, when there is no N that becomes “3N = A” (S15: NO), it is determined whether or not there is N that becomes “3N = A−1” (S17). (S17: YES), “X = B, Y = C, Z = A” is set (S18), and the process proceeds to S20. If there is no N that becomes “3N = A−1” (S17: NO), “X = C, Y = A, Z = B” is set (S19), and the process proceeds to S20. .

  Next, various processes for determining the management graphic pattern are performed. First, the line width D, which is the width in the x-coordinate direction of each component forming the management figure 30, is obtained by “D = 0.1X (mm)” (S20). Then, the coordinate x of the center of the component part of the management figure 30 on the p-th page (1 ≦ p ≦ P) is “x = {(Z−Y) (p−1) / (P−1)} + Y”. It is obtained (S21). Therefore, the center coordinate x of the component part of the management graphic 30 is “x = Y” on the first page, and “x = Z” on the P page which is the last page. Further, since the value of x changes by a certain amount each time the number of pages advances, the management figure 30 is formed on a straight line on the first end aggregate surface 23 (see FIG. 4).

  Next, processing for avoiding overlapping management graphic patterns is performed. First, a management graphic pattern for confidential information for which print data has already been created, which is stored in the management graphic pattern data storage area 131 (see FIG. 3) of the HDD 13, is read (S22). Then, it is determined whether or not there is the same pattern among the read management graphic patterns (S23). Specifically, the line width D, the coordinates of the constituent parts of the management graphic on the first page, the coordinates of the constituent parts of the management graphic on the last page, and the number of printed sheets are compared, and all of them have the same value. In other words, it is determined that the same pattern exists. If the same pattern exists (S23: YES), 0.1 is added to the value of the line width D (S24), and the process returns to the determination in S23. If there is no same pattern (S23: NO), the process returns to the main process.

  Next, returning to the description of FIG. 5, when the management graphic data creation process (S5) is completed, the created management graphic data is stored in the management graphic pattern data storage area 131 in association with the transmission source device and the printing date and time. (S6). Then, a sampling confirmation graphic data creation process is performed (S7).

  As shown in FIG. 7, in the sampling confirmation graphic data creation process, first, the number of printed sheets P is read from the number of printed sheets storage area 1213 (see FIG. 2) (S31), and the horizontal width L of the printing sheet is based on the sheet size. Is read out (S32). Then, the y-coordinate (see FIG. 8) is set with the upper left end of the printing paper as the origin O ′ and the right as positive (S33). The length per unit of the y coordinate varies depending on the lateral width L and is “L / P (mm)”.

  Next, various processes for determining the printing position, width, and the like of the sampling confirmation graphic 40 are performed. First, the line width K, which is the width in the y-coordinate direction of each component part forming the sampling confirmation figure 40, is obtained by “K = L / P (mm)” (S34). That is, the line width K of the constituent part of the sampling confirmation figure 40 is equal to the length per unit of the y coordinate. Then, the coordinate y of the left end of the constituent part of the sampling confirmation graphic 40 on the p-th page is obtained by “y = p−1” (S35), and the process returns to the main process. Accordingly, the coordinate y at the left end of the constituent part of the sampling confirmation graphic 40 is “y = 0” on the first page and “y = P−1” on the P page which is the last page. Further, the value of y changes by one coordinate each time the number of pages advances, and the line width K in the y-coordinate direction of each component is equal to the length of one coordinate. Therefore, the constituent portion of the first page is applied to the upper left end portion of the printing paper, and the constituent portion of the final page is applied to the upper right end portion of the printing paper. Further, on the second end gathering surface 24 (see FIG. 4), the sampling confirmation figure 40 is formed on a diagonal line.

  Next, returning to the description of FIG. 5, when the sampling confirmation graphic data creation process (S7) is completed, print data is created, and the created print data is stored in the created print data storage area 122 of the RAM 12 (S8). . Here, when the management graphic data and the sampling confirmation graphic data are created, print data for printing the constituent parts of the graphic on the edge of each print sheet is created together with the contents of the information included in the image data. Is done. In addition, the width | variety of the direction perpendicular | vertical to the edge part of the component part of the management figure 30 and the extraction confirmation figure 40 is predetermined to the specific value. Then, printing on the printing paper is performed based on the created print data (S9), and it is determined whether the power is turned off (S10). If the power is not turned off (S10: NO), the process returns to the determination of S1, and if the power is turned off (S10: YES), the main process is terminated.

  Next, a management graphic and a sampling confirmation graphic formed on the end gathering surface of the printed material will be described. FIG. 8 is a diagram in which five printing papers 62 constituting the printed matter 61 are arranged, and FIG. 9 is a diagram showing a second end gathering surface 64 when the printing papers 62 shown in FIG. It is.

  First, the management graphic 30 will be described with reference to FIGS. The example shown in FIG. 4 shows the management figure 30 formed by creating the management graphic pattern “print 4” shown in FIG. 3 from the image data of the example shown in FIG. The management graphic data creation process (see FIG. 6) described above is performed. First, since the printing date and time is 20:50 on November 25, “A = 25, B = 20, C = 50” is set, the number of printed sheets is “P = 20”, and the vertical width of the A4 size printing paper. “H = 297” is read, and the x coordinate is set at the right end of the printing paper. Next, since the value of A satisfies “3N = A−1”, “X = B = 20, Y = C = 50, Z = A = 25”, and the line width “D = 2 (mm)”. Is calculated. Then, the center coordinate x of the component part of the management graphic 30 on the p-th page is obtained for each page by “x = −25 (p−1) / 19 + 50”. As a result, the coordinates of the constituent parts of the management graphic 30 on the first page are 50, and the coordinates of the constituent parts on the last page are 25.

  Next, processing for avoiding overlapping management graphic patterns is performed. The created management graphic pattern includes the management graphic pattern of “Print 3” (see FIG. 3) for which print data has already been created, the line width D, the coordinates of the first page component, and the last page component. All the coordinates and the number of printed sheets are the same. Therefore, 0.1 is added to the line width D to make “D = 2.1 (mm), and a management graphic pattern different from the pattern of“ print 3 ”is created. Then, print data is created based on the management graphic pattern, and printing is performed.

  Then, as shown in FIG. 4, the printed management sheets are overlapped in the page order, so that a unique management graphic 30 is formed on the first end aggregate surface 23 formed by gathering the right ends of the printing sheets. The The width of each component constituting the management figure 30 in the x coordinate direction is constant at 2.1 mm. The center of the component 31 of the cover 22 has an x-coordinate value of 50 and a length per unit of the x-coordinate of “297/60 (mm)”. × 297/60 (mm) ”is the downward direction. The center of the component 32 of the last page is “25 × 297/60 (mm)” from the upper right end because the value of the x coordinate is 25.

  Next, the drawing confirmation graphic will be described with reference to FIGS. Here, in order to simplify the explanation, a printed material 61 composed of five printing papers 62 having a lateral width L of 120 mm is taken as an example, and the sampling confirmation formed on the second end gathering surface 64 of the printed material 61 is confirmed. The graphic 60 will be described. The creation of the sampling confirmation graphic pattern is performed by the above-described sampling confirmation graphic data creation processing (see FIG. 7). First, the number of printed sheets “P = 5” and the horizontal width “L = 120” of the printing paper are read, and the y coordinate is set at the upper end of the printing paper. Next, the line width “K = 120/5 = 24 (mm)” in the y-coordinate direction of each component is calculated. Then, the coordinate y of the left end of the constituent part of the sampling confirmation graphic 60 on the p-th page is obtained for each page by “y = p−1”.

  Then, as shown in FIG. 8, the first sheet (front side in FIG. 8) of the printing paper 62 is on the right side by one coordinate (24 mm) from the upper left edge and on the second sheet from the upper left edge. Are printed at the left end of the component 63, each having a width of 24 mm in the y-coordinate direction. Similarly, the third sheet is right by two coordinates from the upper left corner, the fourth sheet is right by three coordinates from the upper left corner, and the fifth sheet is right by four coordinates from the upper left corner. Are printed on the left end of each of them. Therefore, the component 63 of the first sampling confirmation graphic 60 is applied to the upper left end of the printing paper, and the component 63 of the last page is applied to the upper right end of the printing paper.

  Then, as shown in FIG. 9, when the printed printing sheets 62 are overlapped in page order, the left end of the component part 63 of the second to fifth pages coincides with the right end of the component part 63 of the previous page. Further, the right end of the constituent portion 63 of the first to fourth pages coincides with the left end of the constituent portion 63 of the next page. Then, the sampling confirmation graphic 60 is formed on the diagonal line of the second end aggregate surface 64.

  As described above, according to the printing apparatus 1 of the present embodiment, a predetermined figure is formed on the end gathering surfaces 23, 24, 64 formed by gathering the ends of the printing paper. It is possible to create print data for printing a constituent part of a predetermined graphic on the edge of each printing paper. By confirming that the figure is formed without any defect, the user can easily confirm that a part of the confidential information has been extracted, lost, or illegally copied. Furthermore, by associating the device that transmitted the image data to the printing apparatus 1, the printing time, and the like with the graphic, it is possible to manage confidential information included in the image data.

  Specifically, every time print data is created, the print data is created so that a unique management graphic 30 having a different line width D, print position, etc. is formed, and confidential information is printed. The management graphic pattern is stored in association with the device that has issued the time and print instruction. Thereby, confidential information can be managed using the management graphic 30.

  Further, the printing apparatus 1 can create print data for forming the sampling confirmation figures 40 and 60. The constituent parts of the sampling confirmation figures 40 and 60 are printed at positions that coincide with the ends of the constituent parts of adjacent pages, and the sampling confirmation figures 40 and 60 are formed on the diagonal lines of the second end gathering surfaces 24 and 64. It is formed. Accordingly, if a part of the printing paper is extracted, lost, or not overlapped in the page order, the ends of the constituent parts of the sampling confirmation figures 40 and 60 do not coincide with each other. Can be easily confirmed. Further, it is possible to confirm that the first page and the last page are not missing simply by confirming that the sampling confirmation figures 40, 60 are hooked on the corners of the second end portion collecting surfaces 24, 64. Only when the image data transmitted to the printing apparatus 1 is data related to confidential information, print data for forming the management graphic 30 and the sampling confirmation graphics 40 and 60 can be created. Therefore, these figures can be formed on the end aggregate surfaces 23, 24, 64 only when necessary.

  In the above embodiment, the CPU 10 that receives image data from another device via the external communication I / F 19 in S1 shown in FIG. 5 functions as an “image data acquisition unit”. Further, the CPU 10 that determines whether or not the number of printed sheets is plural in S4 of FIG. 5 functions as a “printed number determining unit”, and the management graphic 30 and the sampling confirmation graphic 40 correspond to “predetermined graphic”. Further, in S5 to S8 in FIG. 5, the CPU 10 that creates the print data for printing the constituent parts of the management graphic 30 and the sampling confirmation graphic 40 functions as “print data creation means”.

  In addition, the CPU 10 that creates print data for printing the constituent parts of the sampling confirmation figures 40 and 60 in the sampling confirmation graphic data creation process shown in FIG. 7 and S8 of FIG. 5 functions as “sampling confirmation graphic data creation means”. . Further, in S34 of FIG. 7, the CPU 10 that calculates the line width K of the constituent parts of the sampling confirmation figures 40 and 60 functions as “constituent part width calculating means”. Further, in the management graphic data generation process shown in FIG. 6 and in S8 of FIG. 5, the CPU 10 that generates the print data for printing the components of the management graphic 30 functions as “management graphic data generation means”, and is shown in FIG. The management graphic pattern data storage area 131 of the HDD 13 corresponds to “management graphic pattern storage means”. Further, in S3 of FIG. 5, the CPU 10 that determines whether or not the image data is image data related to confidential information functions as “confidential information determination means”. The print control unit 17 corresponds to “printing means”.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention. First, the management figure 30 and the sampling confirmation figures 40 and 60 of the present embodiment are all figures that look like straight lines on the end aggregate surfaces 23, 24, and 64, but these figures need to be straight lines. Absent. For example, other figures such as a circle, a polygon, a character picture, and a barcode can be printed as the management figure 30 and the sampling confirmation figures 40 and 60.

  Further, in the present embodiment, print data for forming two types of figures, that is, the management figure 30 and the sampling confirmation figures 40 and 60 is created, but print data for forming only one of them may be created. For example, if it is determined in S3 shown in FIG. 5 that the image data is not confidential information, it is possible to create only the sampling confirmation graphic data without creating the management graphic data. In the present embodiment, the print data for forming the management graphic 30 and the sampling confirmation graphics 40 and 60 is created only when the received data is image data of confidential information, but it is not image data of confidential information. In some cases, these figures may be formed.

  In the management graphic pattern data storage area 131 of the HDD 13 (see FIG. 3), the transmission source ID, the date and time, the number of printed sheets, the line width D, the coordinates of the configuration part of the management graphic 30 on the first page, the configuration part on the last page Coordinates are stored. Then, by comparing these values, duplication of the same management graphic data 30 is avoided, but the value stored as the management graphic pattern can be changed. For example, the present invention can be realized without storing the number of printed sheets, and the name of a user who uses the transmission source device may be stored instead of the transmission source ID. Alternatively, a printing apparatus capable of performing color printing may be used, and the color of the component part of the management graphic 30 may be changed and stored as a management graphic pattern.

  In the present embodiment, print data is created in the printing apparatus 1. However, print data for configuring the graphic described in this embodiment is created on a device such as a portable terminal that displays information such as images and characters, and a computer device that can create documents and images, The generated print data may be transmitted to the printing apparatus. That is, the “print data creation apparatus” according to the present invention is not limited to a printing apparatus that performs printing, and can be realized as various other apparatuses. In the present embodiment, when image data is received from another device (S1: YES, see FIG. 5), processing for creating print data is performed. However, image data may be stored in advance, and print data for the image data may be created when a print instruction for the stored image data is input.

  Further, in the present embodiment, the management graphic 30 and the sampling confirmation graphics 40 and 60 are formed on the edge gathering surface by printing the graphic component on the edge of each printing paper, that is, the edge of the printing paper. . Therefore, it is necessary to execute so-called borderless printing, which is a printing process in which no border is formed on the printing paper. Therefore, it may be determined whether or not borderless printing can be executed before print data is created (for example, between S2 and S3 shown in FIG. 5). In this case, if it is determined that borderless printing cannot be performed, the print data for printing only the contents of the image data may be created without creating the print data for printing the components of the graphic (S8, FIG. 5). reference). In addition, when the borderless printing cannot be executed, it may be set not to create the print data itself.
