Description

  The present invention relates to a printing system.

  Conventionally, when PDF (Portable Document Format) direct printing is performed using pre-punched paper, an image may be printed on a hole portion of the paper and the image may be lost. Therefore, the printing position of the image on the paper is adjusted by performing processing such as reducing the image to be printed.

  In addition, as a method for printing an image on paper, a plurality of rectangular drawing data representing a print area is prepared in advance, and output information edited with a predetermined paper size within the paper size based on the selected rectangular drawing data. A method for deriving an enlargement or reduction ratio for printing the image is disclosed (for example, see Patent Document 1).

  However, in Patent Document 1 described above, for example, when images of different document sizes are printed on the same size of paper, even if the magnification for storing the images of different document sizes on a predetermined paper can be derived, for example, It was impossible to print an image on a predetermined sheet with the image arranged in the center.

  That is, for example, in order to place images of different document sizes in the center on a predetermined sheet, image adjustment parameters for placing the image in the center are calculated for each job to be printed and moved by the driver. There is a problem in terms of user convenience because the amount must be entered.

  Here, a conventional printing position adjustment method will be described with reference to FIGS. FIG. 1 is a diagram showing images of different document sizes for a predetermined paper size.

  As shown in FIG. 1, in order to print images of different document sizes on a predetermined paper size, the user is requested to reduce the reduction ratio for placing each image on paper and the reduced image to the center. Therefore, it is necessary to have the amount of movement to be arranged in each print job input for each print job.

  FIG. 2 is a diagram illustrating an example in which images having different document sizes are reduced at the same reduction rate. FIG. 3 shows an example in which the movement amount is calculated so that the original size image of case 1 is arranged at the center of the paper, and the original size images of case 1 and case 2 are moved based on the calculated movement amount. FIG.

  Specifically, as shown in FIG. 2, the user first inputs a reduction ratio so as to fit an image of each original size on a sheet of a predetermined sheet size, and reduces the image. Next, as shown in FIG. 3, the user first calculates the amount of movement, which is a parameter for adjusting the image position, and moves the image so that the original size image of case 1 is placed in the center of the paper. .

  At this time, when the same movement amount as the original size image of case 1 is set for the original size image of case 2, the original size image of case 2 does not fit in the paper and a part of the image is missing. It is printed in the state.

  As described above, if the same setting is collectively set for all jobs to be printed, an image may be lost depending on the document size. Therefore, when printing images with different document sizes, for example, by placing them in the center of the paper, the user must calculate the amount of image movement for each print job and set the amount of movement for each print job. It took a lot of work.

  FIG. 4 is a diagram showing an example in which an original size image of case 1 is arranged at the center of the paper. FIG. 5 is a diagram showing an example in which the original size image of case 2 is arranged at the center of the paper. As shown in FIG. 4, in order to place the original size image of case 1 at the center of the paper, the user sets the x1 position adjustment length in the X-axis direction and the Y-axis direction with the lower left corner of the paper as the origin. Then, the amount of movement with the position adjustment length of y1 is calculated, and the position of the image is adjusted based on the calculated amount of movement.

  Further, as shown in FIG. 5, in order to place the document size image of case 2 in the center of the paper, the user adjusts the position adjustment length of x2 in the X-axis direction and the Y-axis direction with the lower left corner of the paper as the origin. Then, the movement amount to be the position adjustment length of y2 is calculated, and the position adjustment of the image is performed based on the calculated movement amount.

  The present invention has been made in view of the above points, and even when images of different document sizes are mixed in PDF direct printing, by performing the same setting for all print jobs, An object is to arrange and print an image at a position intended by the user.

  In order to achieve the above object, the present invention is a printing system in which a computer terminal and an image forming apparatus are connected via a network, and the image forming apparatus prints an image file transmitted from the computer terminal, The computer terminal includes: a print setting unit that sets a paper size of a sheet on which an image based on an image file to be printed is printed, an arrangement position where the image is arranged, and a magnification of the image; and the image to be printed A file and a control unit that transmits the paper size, the arrangement position, and the magnification set by the print setting unit to the image forming apparatus via the network, and the image forming apparatus includes: Based on the paper size, the arrangement position, and the magnification transmitted from the computer terminal, the data is transmitted via the network.

  The present invention can also be configured as an image forming method, an image forming program, and a recording medium on which the program is recorded.

  According to the present invention, even when images of different document sizes are mixed in PDF direct printing, the same setting is made for all print jobs, whereby the images are arranged at positions intended by the user. Can be printed.

<Example of image position adjustment command by PJL>
Here, the PJL command given for image position adjustment based on the user setting in the job control unit 13 of the client PC 10 described above will be described.

  FIG. 9 is a diagram illustrating an example of image reduction in an image position adjustment command by PJL. The image position adjustment command for image reduction (SCALE) by PJL is given based on a reduction rate of, for example, an input range of 0.1% to 100.0% input by the user.

  As shown in FIG. 9, when the reduction ratio a1 is input to the print job image by the user, a command of the reduction ratio a1 is given as a PJL command, and the print job image is reduced based on the PJL command. The

  FIG. 10 is a diagram showing an example of corner position designation in an image position adjustment command by PJL. The image position adjustment command for the corner (CORNERLOCK) designation (CORNERLOCK) by PJL is input by the user, for example, a reference for setting the printing position when printing an image on printing paper. It is given based on the position of the lower, upper right, lower left, upper left corner (corner), the center of the paper, and the like.

  As shown in FIG. 10, for example, when the center (CENTER) is input as the corner position of the image of the print job on the printing paper by the user, a command for specifying the center position is given as the PJL command. The image of the print job is arranged at the center position with respect to the paper to be printed.

  FIG. 11 is a diagram illustrating an example of the image movement amount in the image position adjustment command by PJL. The image position adjustment command for the image movement amount by the PJL is an image movement amount (VERTICAL MARGIN) in the X-axis direction (left-right direction) as a margin amount at a designated corner position input by the user, and Y It is given based on the image movement amount (HORIZONTALMALGIN) in the axial direction (vertical direction).

  Note that the image position adjustment command for the image movement amount is premised on being used together with the above-described corner position designation (CORNERLOCK) command in FIG. 10, and when the user designates the center (CENTER) in the corner position designation. The command is invalid.

  Based on the image movement amount PJL command described above, the image of the print job moves based on the image movement amount input in the X-axis direction and the Y-axis direction with the designated corner position of the paper to be printed as the origin. To do.

  Here, the image of the print job moves with the designated corner position of the printing paper as the origin. For example, when the image of the printing job is a square image of the document size, the printing paper is designated first. After aligning the corner position with the corner position of the quadrilateral image of the print job (after matching), the print job image will be X with the specified corner position of the print paper as the origin. It means moving in the axial direction and the Y-axis direction.

  The image adjustment command for the image movement amount is, for example, the image movement amount in the X-axis direction positive (+) and the image movement amount in the Y-axis direction with the lower left corner of the printed paper as the origin. Is given a positive (+) sign in the upward direction.

  In this embodiment, in order to improve the operability without considering the sign of the image moving direction with the lower left corner of the paper as the origin, the user designates the corner position using a setting screen as shown in FIG. 11, for example. The image movement amount can be input as the margin amount at the corner position.

  As shown in FIG. 11A, when the user designates the corner position as “lower left” (CORNERLOCK “BOTTOMLEFT”), the sign of the margin amount (image movement amount) on the setting screen is set in the X-axis direction. It can be displayed as positive (+) in the right direction indicated by an arrow and positive (+) in the upward direction indicated by an arrow in the Y-axis direction.

  Similarly, as shown in FIG. 11B, when the user designates the corner position as “lower right” (CORNERLOCK “BOTTOMRIGHT”), the sign of the margin amount on the setting screen is indicated by an arrow in the X-axis direction. Can be displayed as positive (+) in the left direction indicated by, and positive (+) in the upward direction indicated by an arrow in the Y-axis direction.

  Similarly, as shown in FIG. 11C, when the user designates the corner position as “upper left” (CORNERLOCK “TOPLEFT”), the sign of the margin amount on the setting screen is indicated by an arrow in the X-axis direction. It can be displayed as positive (+) in the right direction shown and positive (+) in the downward direction shown by the arrow in the Y-axis direction.

  Similarly, as shown in FIG. 11D, when the user designates the corner position as “upper right” (CORNERLOCK “TOPRIGHT”), the sign of the margin amount on the setting screen is indicated by an arrow in the X-axis direction. It can be displayed as positive (+) in the left direction shown and positive (+) in the downward direction shown by the arrow in the Y-axis direction.

<Flowchart showing Calculation Processing of Calculation Processing Unit 23>
Next, calculation processing of the calculation processing unit 23 in the PDF processing unit 22 of the image forming apparatus 20 will be described. FIG. 12 is a flowchart showing calculation processing of the calculation processing unit.

  As shown in FIG. 12, the calculation processing unit 23 in the PDF processing unit 22 of the image forming apparatus 20 sets the image reduction ratio (SCALE) from the control information of the print job held in the job control holding unit 21. It is judged whether it is (S10). When the reduction rate is set (YES in S10), the calculation processing unit 23 sets the set reduction rate (SCALE value) as the reduction rate of the movement amount calculation information used in the calculation process (S11). ).

  Next, the calculation processing unit 23 determines whether a corner position (CORNERLOCK) is set (S12). If the corner position is not set (NO in S12), a preset default value such as the upper right is set (S13). When the corner position is set (YES in S12), the set corner position (CORNERLOCK value) is set as the corner position of the movement amount calculation information (S14).

  Next, the calculation processing unit 23 determines whether a margin amount (MARGIN value) is set (S15). If the image movement amount is not set (NO in S15), a preset default value “0 (zero)” or the like is set (S16). If the image movement amount is set (YES in S15), the set margin amount (MARGIN value) is set as the image movement amount of the movement amount calculation information (S17).

  Next, the calculation processing unit 23 uses the setting values set in the processing of S11, S14, and S17, the paper size of the print paper to be printed, and the document size of each print job, and print job for the print paper. The printing position of the image is calculated (S18).

  Next, the print processing unit 24 renders an image of the print job based on the print position calculated in the process of S18 (S19). Thereby, the process is terminated.

  When the reduction ratio is set to “100%” in the processing of S11 described above, the calculation of the print position in S18 is performed based on the corner position in S14 and the set value of the image movement amount in S17. The

  In addition, the processes of S10, S12, and S15 described above may be performed prior to the process of S10, or may be performed prior to the process of S12. The order of each process is not limited to the order shown in FIG.

  In addition, the setting values set in each process of S11, S14, and S17 are values input and designated by the user on the client PC 10.

<Specific example when the corner position of the image of the print job is designated as “upper right” or “center”>
Next, a specific example of calculation processing calculated by the calculation processing unit 23 when the corner position of the image of the print job is designated as “upper right” or “center” will be described.

  First, with reference to FIGS. 13 to 15, images of different document sizes (case 1 and case 2) are reduced to a% with respect to the paper size to be printed (vertical: ycm, horizontal: xcm). A calculation process in the case where printing is instructed to bring the image to the upper right of the paper to be printed and to set the margin in the x-axis direction to x3 cm and the margin in the y-axis direction to y3 cm will be described.

  Among the print instructions, the user inputs, for example, “reduction ratio a%”, “corner position is upper right”, and “margins are x3 cm, y3 cm” in the print setting unit 12 of the client PC 10. At this time, as different document sizes, the document size of case 1 is “vertical: y1 cm, horizontal: x1 cm”, and the document size of case 2 is “vertical: y2 cm, horizontal: x2 cm”.

  Here, FIG. 13 is a diagram illustrating an example in which images of different document sizes are reduced to a%. As shown in FIG. 13, when the user inputs a reduction ratio a%, the original size image of case 1 is “vertical: y1 cm × a%, horizontal: x1 cm × a%, relative to the paper size to be printed. To be reduced. The original size image of case 2 is reduced as “vertical: y2 cm × a%, horizontal: x2 cm × a%” with respect to the paper size to be printed.

  Next, FIG. 14 is a diagram showing an example in which an image of a document size reduced to a% is brought to the upper right of the sheet. Even when the user designates the corner position as the upper right corner, the calculation processing unit 23 uses the lower left corner of the paper to be printed as the origin, and the right direction of the x axis is positive (+) and the upper direction of the y axis is positive. Calculate to move the image as (+).

  Therefore, in the case of FIG. 14, the calculation processing unit 23 moves the X-axis direction movement amount = x− (x1 × with respect to the movement amount for moving the document size image of Case 1 with the lower left corner of the paper as the origin. a%), the amount of movement in the Y-axis direction = y− (y1 × a%). Regarding the movement amount of the original size image in case 2, the movement amount in the X-axis direction = x− (x2 × a%) with the lower left corner of the paper as the origin, and the movement amount in the Y-axis direction = y− (y2 × a %).

  Next, FIG. 15 is a diagram illustrating an example in which a margin is set by designating the upper right corner of the sheet as the corner position. As shown in FIG. 15, after the corner position is designated as the upper right corner of the paper by the user, when a margin amount of x3 cm in the x-axis direction and y3 cm in the y-axis direction is input, the calculation processing unit 23 prints The amount of movement of the job image is calculated as follows.

  The calculation processing unit 23 calculates the movement amount of the original size image of case 1 as the movement amount in the X axis direction = −x3 and the movement amount in the Y axis direction = −y3 with the lower left corner of the paper as the origin. Further, the movement amount of the document size image in case 2 is calculated as the movement amount in the X axis direction = −x3 and the movement amount in the Y axis direction = −y3 with the lower left corner of the paper as the origin.

  As described above, the calculation processing unit 23 reduces an image having an original size different from the paper size (vertical: xcm, horizontal: ycm) to a%, brings the image to the upper right of the paper, and the margin in the x-axis direction is x3 cm. When the margin in the y-axis direction is set to y3 cm, calculation is performed as follows for case 1 and case 2 having different document sizes.

  The calculation processing unit 23 moves the X-axis direction movement amount = x− (x1 × a%) − x3 with respect to the original size image of Case 1 with the lower left corner of the paper as the origin, and the Y-axis direction movement amount = y− (y1). Xa%) -y3. For the document size image of Case 2, the movement amount in the X-axis direction = x− (x2 × a%) − x3 with the lower left of the paper as the origin, and the movement amount in the Y-axis direction = y− (y2 × a%) − Calculate as y3.

  Next, a description will be given of calculation processing in a case where images of different document sizes (case 1 and case 2) are reduced to a% with respect to the paper size to be printed, and the original size images are respectively arranged at the center of the paper to be printed. To do.

  In the above case, it is assumed that the user inputs, for example, “reduction ratio a1%” and “arrange in the center” in the print setting unit 12 of the client PC 10.

  Here, FIG. 16 is a diagram illustrating an example in which an image having a different document size is arranged at the center of the sheet. As shown in FIG. 16, when the user inputs a reduction ratio a1%, the original size of case 1 is “vertical: y3cm = y2cm × a1” with respect to the paper size to be printed (vertical: y1 cm, horizontal: x1 cm). %, Width: x3 cm = x2 cm × a1% ”, and the document size of case 2 is reduced as“ vertical: y5 cm = y4 cm × a1%, width: x5 cm = x4 cm × a1% ”.

  Next, FIG. 17 is a diagram illustrating an example of image position adjustment in which an original size image of case 1 is arranged at the center of the paper. FIG. 18 is a diagram illustrating an example of image position adjustment in which an original size image of case 2 is arranged at the center of the sheet.

  As shown in FIGS. 17 and 18, when the user sets the image of the print job to be arranged at the center of the paper, the calculation processing unit 23 determines the movement amount of the original size image of Case 1 on the lower left side of the paper. With the corner as the origin, the movement amount in the X-axis direction = (x1-x3) / 2, and the movement amount in the Y-axis direction = (y1-y3) / 2. As for the movement amount of the document size image in Case 2, the movement amount in the X-axis direction = (x1−x5) / 2, and the movement amount in the Y-axis direction = (y1−y5) with the lower left corner of the paper as the origin. ) Calculated as ÷ 2.

  In this way, the calculation processing unit 23 prints the print job for the paper to be printed based on the reduction ratio for the image of the print job input by the user, the corner position specified by the user, and the margin amount set based on the corner position. The amount of movement for adjusting the position of the image is calculated. Further, the calculation processing unit 23 can use the following expression as a calculation processing method for calculating the print position of the image. It is assumed that the reduction rate input by the user is a%, the paper to be printed (vertical: y1 cm, horizontal: x1 cm), and the document size of the print job is “vertical: y2 cm, horizontal: x2 cm”.

  When the margin position is (x3, y3) with the corner position at the upper right, the movement amount of the image of the print job with the lower left corner position of the paper as the origin is the movement amount in the X-axis direction = x− ( x2 × a%) − x3, and the amount of movement in the Y-axis direction = y− (x2 × a%) − y3.

  When the margin position is (x3, y3) with the corner position at the upper left, the movement amount of the image of the print job is the movement amount in the X-axis direction = x3, Y with the lower left corner position of the paper as the origin The amount of movement in the axial direction = y− (x2 × a%) − y3.

  When the corner position is set to the lower right and a margin of (x3, y3) is set, the movement amount of the image of the print job with the lower left corner position of the paper as the origin is the movement amount in the X-axis direction = x− It is assumed that (x2 × a%) − x3 and the movement amount in the Y-axis direction = y3.

  When the margin position is (x3, y3) with the corner position at the lower left, the movement amount of the image of the print job is the movement amount in the X-axis direction = x3, Y with the lower left corner position of the paper as the origin Axial movement amount = y3.

  When the center position is set, the movement amount of the image of the print job is the movement amount in the X-axis direction = (x1− (x2 × a%)) / division with the lower left corner position of the paper as the origin. 2. Amount of movement in the Y-axis direction = (y1− (y2 × a%)) / 2.

  The calculation formula of the movement amount by the calculation processing unit 23 described above can be described as follows. That is, the movement amount of the image of the print job is calculated by the movement amount = the length of the paper size, “the length of the document size × the reduction rate (a%)”, and the margin amount (image movement amount) by the margin setting.

  In the calculation formula for the amount of movement, the length of the paper size is 0 (zero) when the X-axis direction is set to the paper size length when the corner position is set to the right corner, and to the left corner. ) If the Y-axis direction is set as the corner position at the upper corner of the paper, the length of the paper size is set. If the Y-axis direction is set at the lower corner of the paper size, 0 (zero) is set.

  Further, “original size length × reduction ratio (%)” is set to the left side by adding a negative (−) sign when the X axis direction is set to the right corner as the corner position. And 0 (zero). A negative (-) sign is added if the Y-axis direction is set to the upper side as the corner position, and 0 (zero) is set if the Y-axis direction is set to the lower side.

  The margin amount is added with a negative (-) sign when the X-axis direction is set to the right corner as the corner position, and is positive (+) when set to the left corner. If the Y-axis direction is set as the corner position at the upper corner, a negative (−) sign is added, and if it is set at the lower corner, it becomes positive (+).

  When the user inputs a margin amount on the setting screen shown in FIG. 11, the calculation processing unit 23 refers to the next table and adds a code to the input margin amount and uses it in the above calculation formula. be able to. For example, when the corner position is at the lower right and the margin of (x3, y3) is set, as shown in the following table (Table 1), the margin amount (image movement) by the margin setting of the image of the print job Amount) is the amount of movement in the X-axis direction = −x3 and the amount of movement in the Y-axis direction = y3 with the lower left corner position of the paper as the origin.

<Regarding back side alignment in duplex printing>
Next, back surface alignment when double-sided printing is set by the user will be described. FIG. 19 is a diagram illustrating an example of back surface alignment in double-sided printing.

  As shown in FIG. 19, in the case of long-side binding in double-sided printing, setting is made so that the back side image is arranged behind the front side. For example, when specifying the corner position of the front image and moving it to the lower right, the rear image is arranged at the lower left instead of the lower right.

  As a result, when punch holes are made, post-processing is performed without missing the image on the back surface.

  In order to perform the above-described processing, the calculation processing unit 23 refers to the next table (Table 2) when the single-sided printing or the double-sided printing is set and the corner position designation (CORNERLOCK) is set. Set the corner position (origin) of the image.

<Flow chart for back side alignment in duplex printing>
Next, a flowchart for back surface alignment when duplex printing is set will be described. FIG. 20 is a diagram illustrating a flowchart for back surface alignment in double-sided printing.

  As shown in FIG. 20, the calculation processing unit 23 determines whether or not double-sided printing is performed (S20). In the case of double-sided printing (YES in S20), the calculation processing unit 23 determines whether long-side binding is performed (S21). In the case of long-edge binding (NO in S20), the calculation processing unit 23 determines whether the corner position designation (CORNERLOCK) of the image of the print job on the surface of the paper to be printed is the lower right corner of the paper to be printed. (S22).

  If it is the lower right corner (YES in S22), the corner position (back surface origin) of the print job image on the back surface of the paper is set to the lower left corner of the paper (S23), and the process is terminated. If it is not the lower right corner (NO in S22), it is determined whether the corner position designation on the surface of the paper is the upper right corner of the paper (S24).

  If it is the upper right corner (YES in S24), the back surface origin is set to the upper left corner of the paper (S25), and the process is terminated. If it is not the upper right corner (YES in S24), it is determined whether the corner position designation on the surface of the paper is the lower left corner of the paper (S26).

  If it is the lower left corner (YES in S26), the rear surface origin is set to the lower left corner (S27), and the process is terminated. If it is not the lower left corner (NO in S26), the back surface origin is set to the upper left corner of the paper (S28), and the process is terminated.

  In the process of S21, if the long side binding is not performed (NO in S21), that is, if the short side binding is performed, it is determined whether the corner position designation on the surface of the paper is the lower right corner of the paper (S29). If it is the lower right corner (YES in S30), the back surface origin is set to the upper right corner of the paper (S30), and the process is terminated. If it is not the lower right corner (NO in S29), it is determined whether the corner position designation on the surface of the paper is the upper right corner of the paper (S31). If it is the upper right corner (YES in S31), the back origin is set to the upper right corner of the paper (S32), and the process is terminated. If it is not the upper right corner (NO in S31), it is determined whether the corner position designation on the surface of the paper is the lower left corner of the paper (S33). If it is the lower left corner (YES in S33), the back surface origin is set to the upper left corner of the paper (S34), and the process ends. If it is not the lower left corner (NO in S33), the back surface origin is set to the lower left corner of the paper (S35), and the process ends.

  As a result, when punch holes are formed during double-sided printing, post-processing is performed without missing the image on the back side of the printed paper.
