Next, when performing double-sided printing of a plurality of pages of print data in the printing apparatus of the present embodiment having the above configuration, a process of determining the order of printing of a plurality of pages of print data (hereinafter, referred to as a scheduling process). Will be described below.

First, FIG. 3 is a diagram for explaining a scheduling process in the case of performing normal double-sided printing without performing the single-sided copy process according to the present invention. FIG. 3A shows a memory map of the RAM 24 for storing print data. FIG. 3B shows the order in which the print data stored in the RAM 24 is printed out from the output unit 26, and this order information is stored in the output queue 27. Further, FIG. 3C shows the output position of the print data of each page actually printed on the printing paper by the printing output of the output unit 26 (the number of the front side or the back side of the printing paper).

When the host computer 20 sends, for example, six pages of print data to the printing apparatus 21, the RAM
As shown in FIG. 3A, print data for six pages is stored in the order of the pages (in the order of reception).

Here, in the case of normal double-sided printing, the order in which the print data is printed out is the same as the order in which the print data is stored in the RAM 24. Therefore, as shown in FIG. Output queue information is stored in order up to 6. When print data of six pages is printed out on both sides of the printing paper 30, as shown in FIG. 3C, the printing data of each page is printed on the front and back of the three printing papers 31, 32, and 33, respectively. 1 and Page-2,
Page-3 and Page-4, Page-5 and Page
Printing is performed in the order of -6.

FIG. 4 is a diagram for explaining a scheduling process in the case of performing a single-sided copy process in double-sided printing according to the present invention.

When the host computer 20 transmits, for example, four pages of print data to the printing device 21, the RAM
4 stores print data for four pages as shown in FIG.

Here, it is assumed that the page-1 print data includes a copy designation command for validating the one-sided copy processing according to the present invention. In this case, the output queue 27
As shown in (b), the print data of the page designated as Copy-1 is scheduled so as to be repeatedly output every other page instead of the order in which the print data of each page is received, and the print order information is stored. You.

If so, in step S53, the page number of the print data to be copied and information on the print side (front or back) are stored in the copy side information section 28. Thereafter, the process proceeds to step S56.

On the other hand, if it is determined in step S52 that one page of print data stored in the RAM 24 in step S51 has not been designated for copying, then in step S54, one page of print data is set in the output queue 27 next. It is determined whether or not the print surface of the print data (the odd-numbered front surface and the even-numbered back surface in the order in the output queue 27) is the same as the copy surface stored in the copy surface information unit 28. In step S55, the order information for printing out the print data of the copy page is stored in the output queue 27. As a result, the printing surface of the print data for one page stored in the RAM 24 in step S51 is the opposite surface to the original surface (the odd-numbered front surface and the even-numbered back surface in the receiving order). After step S55, the process proceeds to step S56.

If it is determined in step S54 that the print surface of the print data for one page stored in the RAM 24 in step S51 is not the same as the copy surface stored in the copy surface information section 28, the process also proceeds to step S56.
