A printing apparatus includes a printing mechanism, a control circuit, and a power supply circuit. The power supply circuit includes a main power supply that supplies a voltage, an input voltage control circuit that, based on the voltage, generates a plurality of driving voltages for the control circuit and a reset signal for the control circuit, a switching circuit that supplies the voltage to the input voltage control circuit, an enabling circuit that, based on the voltage, supplies an enable signal to the input voltage control circuit, and a multi-contact switch that, when being in an ON state, supplies the voltage to the switching circuit and the enabling circuit. The input voltage control circuit receives the enable signal from the enabling circuit after elapsing a predetermined period, generates, based on the enable signal, the plurality of driving voltages and the reset signal, and supplies to the control circuit. 1.
