に可変するのは、実質上困難であった。When the heating element of a thermal head continuously generates heat, its temperature gradually rises, and even with the same applied voltage, there is a phenomenon in which the heat generation energy increases. As a conventional technique, a method is generally known in which the voltage applied to the thermal head heating element is varied depending on the temperature of the thermal head heating element. However, with this method, it is practically difficult to continuously vary the applied energy.
