<P>PROBLEM TO BE SOLVED: To solve the following problem that: because print positions of the front face and the rear face are displaced due to the reduction of reducing an image when the image to be printed is not stored in a printable range, there is a problem that a margin of a binding margin is not correctly set to cause displacement in binding margin printing. <P>SOLUTION: When performing double-sided printing to a printer having different printing ranges on the front face and the rear face, the double-sided printing is not performed in a page wherein print data exceed a printing range, and reprinting is performed after the completion of the double-sided printing. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a method for controlling a printer device connected to an information processing device such as a personal computer.

  When performing double-sided printing with the printer, if the printable range of the printer is exactly the same on the front and back sides, there will be no shift in the printing position on the front and back sides, but depending on the printer, printing on the front and back sides is possible. The range may be different, and when double-sided printing is performed with such a printer, the print result may be missing on the side with the smaller printable range.

As a method for avoiding missing images during double-sided printing, there is a measure to reduce the image when the image to be printed does not fall within the printable range. (For example, see Patent Document 1 and Patent Document 2)
JP 09-216434 A JP 2002-066726 A

  However, in the above conventional example, when the image to be printed does not fit in the printable range, the image is reduced, so that the printing positions on the front surface and the back surface are shifted. For this reason, in margin printing, there is a problem that the margin portion of the margin is shifted without being set correctly. In addition, when two pages of data are printed on one sheet of paper by bookbinding printing or the like, and the paper is folded in half, the printing position is shifted, which makes the appearance worse.

  An object of this invention is to provide the information processing apparatus which solved the said subject.

  The present invention provides a means for creating print data for double-sided printing in accordance with the larger printable range in a printer having different printable ranges for the front and back sides during double-sided printing, and the print data exceeds the actual printable range. For each page, means for storing print data, means for storing the number of times duplex printing has been performed, and means for retransmitting the stored print data.

  With the above configuration, when performing double-sided printing for printers with different print ranges on the front and back sides, do not perform double-sided printing for pages whose print data exceeds the print range, and reprint after completion of double-sided printing. Therefore, it is possible to prevent the printing result from being lost and to perform printing without shifting the printing position on the front and back surfaces.

[First embodiment]
Embodiments of the present invention will be described below in detail with reference to the drawings.

  FIG. 1 is a block diagram illustrating a configuration of a printer in the embodiment.

  In the figure, 1 is the printer body. 2 is a system bus, 3 is a USB interface, and 4 is a network interface, which are connected to the information processing apparatus of FIG. 2 via Ethernet (registered trademark). Reference numeral 5 denotes a CPU, and reference numeral 6 denotes a memory which stores an image color conversion table, a profile, and the like. A flash ROM 7 stores a program for image processing and the like. Reference numeral 8 denotes an EEPROM that stores a list of devices that hold tables and profiles.

An operation panel 10 includes a number of keys for setting printers and a display unit for displaying printer statuses. A printer engine 11 includes a print head for printing data from the host and a motor for driving the print head. A head recovery unit 12 in the printer engine performs recovery operations such as suction, wiping, and capping by a print head recovery motor or the like.

  FIG. 2 is a block diagram illustrating a configuration of an information processing apparatus that issues a print instruction in the embodiment.

  In the figure, 13 is an information processing apparatus main body, 14 is a system bus, 15 is a CPU that controls the entire information processing apparatus, 16 is a memory, and 17 is an external storage unit in which programs and data are stored. Reference numeral 18 denotes a display unit. A USB interface 19 is connected to the printer via a cable. Reference numeral 20 denotes a network interface, which is connected to the printer via Ethernet (registered trademark).

  FIG. 3 shows an example of commands and data transmitted to the printer during duplex printing.

  In the figure, reference numeral 21 denotes data transmitted to the printer by double-sided printing. Since some pages exceed the printable range, page break data is not transmitted to the printer. Data 22 is sent to the printer when retransmitting data that could not be transmitted, and page break data is transmitted to eject a page that has been correctly printed on both sides.

  FIG. 4 shows an example of a dialog displayed when reprinting a page that could not be printed on both sides.

  Hereinafter, according to the flowchart shown in FIG. 9, when performing duplex printing for a printer having the above-described configuration and having a printing range different between the front surface and the back surface, duplex printing is performed for pages whose print data exceeds the printing range. First, a detailed description will be given of a method for preventing printing results from being lost by performing reprinting after completion of double-sided printing, and enabling printing without shifting the printing position on the front and back surfaces.

  In step 1, the page break counter used at the time of duplex printing is cleared, and a duplex printing command is transmitted to the printer. The page break counter stores the number of page break commands transmitted when reprinting a page that could not be printed on both sides.

  In step 2, data for one page is created. One page of data is created in accordance with the surface having a large printable range, and it is determined whether or not the data exists beyond the printable region of the surface having a small printable range in the creation process. In step 3, it is determined whether the page data to be printed is coincident with the printable range of the printer. That is, it is determined whether or not printing is performed on a surface having a large printable range. If there is a match, the process proceeds to step 8 if the printable range of the printer may be exceeded. In step 4, it is determined whether the data created in step 2 is within the print range. Whether it is within the printing range is determined and stored at the time of data creation in step 2. If the data is within the print range, the process proceeds to step 7;

  In step 5, since the page data cannot be transmitted to the printer, the number of page break data to be transmitted before reprinting the page data is stored, and the counter is cleared. The page data that could not be transmitted in step 6 is saved, and the process proceeds to step 9. In step 7, the page break counter is incremented by 1, and the process proceeds to step 8. In step 8, the data for one page is transmitted to the printer. In step 9, it is determined whether data of all pages has been transmitted. If the transmission is finished, the process returns to step 2 if the process is not finished.

  The data transmitted to the printer at the time when transmission of all the data is completed is as indicated by 21 in FIG. In this example, double-sided printing of all eight pages is performed, and only the page break data is transmitted to the printer because the data on the fifth page exceeds the printable range.

  In step 10, it is determined whether there is data that could not be transmitted and was saved. If there is stored data, the process goes to step 11; In step 11, the page break counter is saved. This is for discharging the remaining paper after printing the last page data at the time of reprinting. In step 12, a dialog as shown in FIG. 4 is displayed in order to reprint the data that could not be printed by double-sided printing, and the user is notified to set all the papers printed on both sides in the printer. Proceed to step 13. In step 13, it is determined whether or not the dialog OK is selected. If OK is selected, the process goes to step 14; otherwise, the process ends. In step 14, the stored page data is reprinted. In reprinting, the page break command corresponding to the number of page break counters stored in step 5 and step 11 and the page data saved in step 6 are transmitted to the printer in the order in which they are stored. In the example of 22 in FIG. 3, the data of the fifth page among the data of all eight pages of the first double-sided printing could not be transmitted. The page command is sent twice, the fifth page of data is sent, then the page break command is sent again, and the last paper is discharged.

  With the above configuration, when performing double-sided printing for printers with different print ranges on the front and back sides, do not perform double-sided printing for pages whose print data exceeds the print range, and reprint after completion of double-sided printing. Therefore, it is possible to prevent the printing result from being lost and to perform printing without shifting the printing position on the front and back surfaces.

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described in detail with reference to the drawings.

  Since the configuration is the same as in FIGS. 1 and 2, detailed description thereof is omitted.

  FIG. 5 shows an example of commands and data transmitted to the printer during duplex printing.

  In the figure, reference numeral 24 denotes data transmitted to the printer by double-sided printing. Since some pages exceed the printable range, page break data is not transmitted to the printer. Reference numeral 25 denotes data sent to the printer when data that could not be transmitted is retransmitted.

  FIG. 6 shows an example of a dialog displayed when reprinting a page that could not be printed on both sides.

  Hereinafter, according to the flowchart shown in FIG. 10, when performing duplex printing for a printer having the above-described configuration and having a printing range different between the front surface and the back surface, duplex printing is performed for pages whose print data exceeds the printing range. First, a detailed description will be given of a method for preventing printing results from being lost by performing reprinting after completion of double-sided printing, and enabling printing without shifting the printing position on the front and back surfaces.

  In step 15, the page break counter used at the time of duplex printing is cleared, and a duplex printing command is transmitted to the printer. The page break counter stores the number of page break commands transmitted when reprinting a page that could not be printed on both sides.

  In step 16, data for one page is created. One page of data is created in accordance with the surface having a large printable range, and it is determined whether or not the data exists beyond the printable region of the surface having a small printable range in the creation process. In step 17, it is determined whether the data created in step 16 is within the print range. Whether it is within the printing range is determined and stored at the time of data creation in step 16. If the data is within the print range, the process proceeds to step 19;

  The page data that could not be transmitted in step 18 is saved, and the process proceeds to step 20. In step 19, the data for one page is transmitted to the printer. In step 20, it is determined whether data of all pages has been transmitted. If the transmission is completed, the process returns to step 21. If not, the process returns to step 16.

  The data transmitted to the printer when the transmission of all data is completed is as shown by 24 in FIG. In this example, double-sided printing of all 8 pages is performed, and only the page break data is transmitted to the printer because the data on the third and fifth pages exceeds the printable range.

  In step 21, it is determined whether or not there is data that cannot be transmitted. If there is stored data, the process goes to step 22; In step 22, in order to reprint the data that could not be printed by double-sided printing, a dialog as shown in FIG. 6 is displayed to notify the user to set only the paper that has not been double-sided printed in the printer, Proceed to step 23. In step 23, it is determined whether or not the dialog OK is selected. If OK is selected, the process goes to step 24. Otherwise, the process ends. In step 24, the stored page data is reprinted. The reprinting is transmitted to the printer in the order in which the page data stored in step 18 is stored. In the example 25 of FIG. 5, the data for the third and fifth pages could not be transmitted among all the eight pages of data for the first double-sided printing, so a single-sided printing command is sent to the printer for reprinting. After that, only the commands on the third and fifth pages are transmitted to the printer.

  With the above configuration, when performing double-sided printing for printers with different print ranges on the front and back sides, do not perform double-sided printing for pages whose print data exceeds the print range, and reprint after completion of double-sided printing. Therefore, it is possible to prevent the printing result from being lost and to perform printing without shifting the printing position on the front and back surfaces.
