Abstract
A semiconductor device is adapted for controlling energization of a heating element that performs printing. The semiconductor device includes: a strobe signal input unit receiving a printing strobe signal that causes the heating element to generate heat for printing; a preheating strobe generation circuit generating a preheating strobe signal that causes the heating element to preheat by compressing a waveform of the printing strobe signal in a time axis direction; and an output controller outputting a control signal that controls energization of the heating element based on the printing strobe signal and the preheating strobe signal.
