Method for downloading firmware of peripheral equipment, and peripheral equipment

Abstract

An upper-level equipment download firmware to a peripheral equipment while information having been set from the upper-level equipment is inherited after downloading. The peripheral equipment includes a controller for controlling the peripheral equipment through the execution of firmware and nonvolatile memories for storing information for the controller. The controller receives the firmware from upper-level equipment, and preserves in the nonvolatile memories the information set from the upper-level equipment to the peripheral equipment. At the time of initializing the peripheral equipment after receiving the firmware, the controller reads out the set information preserved in the nonvolatile memories, and resets the set information to the peripheral equipment.
