Abstract: An electronic device includes a storage unit that stores configuration data related to the electronic device, a configuration data writing unit that writes configuration data from the storage unit to the external storage device when electronic device power turns off, a configuration data updating unit that, after the configuration data is written to the external storage device, executes a deletion process to delete the configuration data in the storage unit, or an initialization process that resets the configuration data in the storage unit to a default initialization value, a configuration data reading unit that reads the configuration data from the external storage device when electronic device power turns on, a configuration unit that configures the electronic device based on the read configuration data, and a configuration data deletion unit that deletes the configuration data stored in the external storage device after the configuration unit completes configuring the electronic device.

Abstract: An order management device that is used connected to an order entry terminal and a display device, includes: a print data acquisition unit that acquires print data from the order entry terminal, the print data being data for printing an order ticket and including an identification code identifying a customer and order information denoting order content; a display data generating unit that extracts the identification code and order information for one or more items from the acquired print data, sorts the order information by identification code, and generates display data for displaying the order information on the display device; and a display data output unit that outputs the generated display data to the display device.
