Printer imposing restriction on power supply to external device from power supply device

Abstract

A printer includes a print engine, a power supply circuit, and a controller. The print engine is configured to perform a print operation in which an image is printed using power from a power supply device. The power supply circuit is configured to supply power to an external device from the power supply device. The controller performs an obtaining process including obtaining a parameter. The parameter indicates a power-supply load on the power supply device. The controller performs a first restricting process when the parameter is greater than or equal to a first threshold value. The first restricting process includes imposing a restriction on the power supplied to the external device from the power supply device via the power supply circuit.
