Abstract
An interface device backs up printer settings and operating history data of printer so that the settings and history data can be easily restored. A nonvolatile memoryin the printerstores printer settings data. Commands from a hostare passed by the interface deviceand received by a receiverwithin the printer. If the command data is a print command, the print mechanismprints the specified text or image. If the command data is a command for updating the settings data, the corresponding settings data in the nonvolatile memoryis updated and at an appropriate backup time the updated settings data is copied to a nonvolatile memoryin the interface device. The settings data backed up into the interface devicecan then be restored back to the printer's nonvolatile memoryat an appropriate data restore time.
