Field of the Invention The present invention relates to a printing control method for a cut sheet printing apparatus having a single-sided printing function and a double-sided printing function. 2. Description of the Related Art Some cut sheet printing apparatuses have a single-sided printing function for printing on only one side of a cut sheet and a double-sided printing function for printing on both sides of a cut sheet. The single-sided printing and the double-sided printing have different paper passage paths (hereinafter, referred to as paths). When printing is performed in the order of two-sided printing, one-sided printing, and two-sided printing in accordance with a command from a higher-level device. After the printing is completed, switching of paths is performed, and single-sided printing is started. Similarly, when switching from single-sided printing to double-sided printing, double-sided printing is started by switching paths after the single-sided printing is completed. As described above, when printing is performed in the order of two-sided printing, one-sided printing, and two-sided printing, when the two-sided printing is completed, the path is switched to start one-sided printing. After the printing is completed, the path is switched to start double-sided printing, so that it takes time to wait for the printing to be completed or to switch the path, which causes a reduction in the efficiency of print output. In particular, in the case where printing is performed in the above order, when the number of single-sided prints set between two-sided printing is small, the efficiency is significantly reduced. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve the efficiency of print output in a cut sheet printing apparatus when performing printing from double-sided printing to single-sided printing and switching back to double-sided printing. SUMMARY OF THE INVENTION An object of the present invention is to provide a print control method for a cut sheet printing apparatus having different paper passage paths for single-sided printing and double-sided printing. When performing , switch from double-sided printing to single-sided printing
Counting from the first single- sided printed page, and if the number of consecutive single-sided printed pages is equal to or less than a predetermined number, rewrite the single-sided printing information to double-sided printing information with the back side blank.
Printing using the paper passage path for double-sided printing
Counts from the first single-sided page switched to single-sided printing
When the number of continuous single-sided printed pages exceeds the predetermined number, the printing is performed by switching the paper passage path from the double-sided paper passage path to the single-sided paper passage path. As described above, by rewriting the print information of the single-sided printing to the print information of the double-sided printing with the back side being blank, the single-sided printing performs the double-sided printing of the back side blank. Therefore, since continuous printing of double-sided printing is performed, there is no need to wait for printing completion or switch paths. An embodiment of the present invention will be described below with reference to the drawings. In the present invention, the printing information of single-sided printing up to the first five pages, which has been switched from double-sided printing to single-sided printing, is rewritten to printing information of double-sided printing with a blank back side, and printing is performed as it is in a double-sided printing pass without switching paths. Do. If the designation of single-sided printing is continued even after the sixth page, switching to the single-sided printing pass is performed at that time, and normal single-sided printing is performed. If the single-sided printing designation has been completed by page 5 and you are returning to double-sided printing again,
The duplex printing is continued by the duplex printing pass, and the page counter of the simplex printing is reset. FIGS. 1 and 2 are flowcharts showing a print control method according to the present invention. When the printing method is received from the host device, the previous printing method is stored as shown in FIG. 1 (step 101). Next, print settings (step 10
2) is performed to determine whether the current printing method is single-sided printing or double-sided printing (step 103). If the current printing is double-sided printing, the counter i is cleared to 0 (step 10).
6) End the process. If the current printing is single-sided printing, the previous printing method (stored in step 101)
Is determined whether the printing is double-sided printing or single-sided printing (step 104).
If the previous time was double-sided printing, the counter i is set to 5 (step 105), and the process ends. Next, when the printing information for one page from the upper apparatus is completed, as shown in FIG. 2, after the creation of the print data (Step 201), if the counter i set at the time of receiving the printing method is 0 ( Step 202) The process ends.
If the counter i is not 0, a blank one page creation process (step 203) is performed. A description will be given of an example of the processing content of the blank page one page creation processing when two pieces of printing information, one sheet for double-sided printing and one sheet for one side, are received. At the time of single-sided printing reception, the print information storage area is processed by one side, and at the time of double-sided printing reception, the print information storage area is processed by one side on the front side and one side on the back side.
Therefore, in the conventional process, the process is performed as shown in FIG. 4, but in the blank page creation process, the print information of the single-sided print subsequent to the double-sided print is stored as shown in FIG. 3. Create in area 2. Then, print information of blank page information is internally created in the print information storage area 3 on the back side of the duplex printing. After one blank page creation process is completed, a value obtained by subtracting 1 from the value of the counter i is set in the counter i (step 204).
With the above control procedure, single-sided printing can be performed using a double-sided printing pass. According to the present invention, by rewriting print information of single-sided printing to print information of double-sided printing with a blank back side, when the number of single-sided printed pages is less than a predetermined number, it is treated as double-sided printing. Therefore, the efficiency of print output can be improved.
