A thermal printer is comprised of a buffer RAM for storing print data, a thermal head, and a CPU for controlling the feed of current to the thermal head. The thermal head includes a number of heating resistor elements. When current is fed to the heating resistor elements during a print period, the heating resistor elements of the thermal head are heated to color a thermosensible paper. The CPU controls a current feed period of the thermal head during the present print period in accordance with both the present print data stored in a buffer RAM and the print data in a previous print period preceding to the present print period.
