ABSTRACT:
A thermal transfer printer comprises a temperature detector which detects the temperature of a thermal head, a heating controller which performs heating processing on the thermal head to increase the thermal head temperature to a temperature higher than a print-permit temperature, a heat radiation controller which performs heat radiation processing on the thermal head to reduce the thermal head temperature to the print-permit temperature, and a control unit which controls a temperature slope of the thermal head to be a descending slope to be the print-permit temperature by radiating heat from the thermal head. The thermal transfer printer obtains an excellent print result.
