に供給することを特徴とするサーマルプリンタ。 In devices that perform printing by supplying printing energy from a thermal head drive circuit to a thermal head, there are two types: a head temperature sensor that detects the temperature of the board on which the thermal head is mounted, and an environmental temperature sensor that detects the reference environmental temperature. The thermal head drive circuit supplies the thermal head with printing energy determined by detection signals of both a head temperature signal output from the head temperature sensor and an environment temperature signal output from the environment temperature sensor. A thermal printer characterized by:
