Background image data representing a background image are stored in a printer in advance. When print data representing receipt print information are obtained from a personal computer, the background image and the receipt print information are printed on a receipt so as to overlap each other. Here, a start character string and an end character string are detected from the print data, and the background image is printed in a print region equivalent to the region between lines where the start character string and the end character string are printed. A color-graphic-based receipt can thus be issued without changing a monochrome-text-based application program.
