Abstract
A thermal printer performs printing on a paper based on printing density data input. The thermal printer includes a thermal head having at least one heating element; a temperature detector which detects a temperature of the thermal head; and a control part which is connected to the thermal head and the temperature detector, receives the printing density data, and controls an amount of energy to be supplied to the heating element based on the printing density data. The control part stores therein a printing density-energy supply amount table which sets forth an amount of energy to be supplied to the heating element to perform printing with certain printing densities at certain head temperatures. The printing density-energy supply amount table sets forth that the amount of energy to be supplied is greater than zero at the printing density of zero if the head temperature is lower than a predetermined temperature.
