Abstract
A CPU of a thermal printer operates an estimated temperature of a thermal head 2 after printing image data of one line, based on image data of each line stored in a memory and a pulse width corresponding to the temperature of the thermal head and the like. The CPU compares the estimated temperature with the temperature of the thermal head after the printing, and the thermal head is released from its contact with a platen roller when the temperature of the thermal head is higher than the estimated temperature.
