ABSTRACT:
There are provided a printing apparatus having an arrangement capable of stably applying a voltage without using any special power supply control unit, and a power supply control method. According to the method, a signal representing a change of an image signal is generated in the ASIC of the printing apparatus main body. A discharge circuit which is arranged on the power supply path extending from the power supply unit and quickly decreases the voltage upon power-off is also used as a circuit for stabilizing the voltage. While a power supply unit and DC/DC converter with a conventional arrangement are adopted without adding any new component, a compact, low-cost power supply circuit with high voltage stability is implemented.
