Abstract
A printing apparatus which is capable of performing excellent printing without leaving a conveying roller mark on roll paper for printing of a next image even when the operation of the apparatus is stopped for cooling. A thermal head performs printing by sequentially transferring a plurality of color inks coated on an ink ribbon onto the roll paper drawn out from a cartridge, in superimposed relation. The roll paper is conveyed in a state nipped by a conveying roller pair. A thermistor detects a temperature within the apparatus. After completion of printing in one color, the roll paper is conveyed to a print start position at a first conveying speed, for execution of printing in another color. When the detected temperature is higher than a predetermined value, the roll paper is conveyed to the print start position at a second conveying speed which is slower than the first conveying speed.
