Abstract
A printer prints all print data when an inverted print mode is selected for printing even if an insufficient memory state occurs in the image conversion buffer. If the roll paper printeris set to the inverted print mode and an insufficient memory monitoring unitdetects an insufficient memory state in the image conversion bufferbefore the inverted image data generating unitconverts and writes all of the received print data to a print data break to the image conversion buffer, the print mode switching unitchanges the print mode from the inverted print mode to the normal print mode, and the normal printing unitprints the print data from the beginning. Because the print data is printed from the beginning when the inverted image data cannot be correctly generated because of insufficient memory, there is no loss of information contained in the print data.
