The object of the invention is to automatically select an optimum printing device according to the characteristics of a page in units of pages to print the page, thereby reducing the load on the operator in print processing. For this purpose, it is determined in units of pages whether data to be printed contains color information. If color information is present, a color flag is set to ON. When the color flag is ON, print data prepared and developed in a page buffer is sent to a color printer. When the color flag is OFF, the print data prepared and developed in the page buffer is sent to a monochromatic printer.
