System and method for sequential power supply control of prioritized networked printers from the highest priority via a manual switch on of a network printer regardless of its priority

摘要

A remote power-supply control method allowing the burdens on the host computer with power-supply control of a plurality of network printers to be reduced is disclosed. After assigning priorities to the printers, at each of the printers, an address of another printer having a next-lower priority assigned thereto is stored. When a power-supply control signal has been received, the main power supply thereof is controlled depending on the power-supply control signal and the power-supply control signal is sent to the other printer having the next-lower priority assigned thereto.
