PURPOSE: A printing apparatus, a data storage medium, an interface device, a printer control method, and an interface control method are provided to use for backup storage of printer settings data and operating history data, an interface device, a printer control method, an interface control method, and a computer-readable data storage carrying a program that achieves the backup storage functions. CONSTITUTION: A printing apparatus and interface device backup operating parameters and operating history data so that the data can be easily restored. A memory(109) in the printer(101) nonvolatilely stores operating parameter data. Commands from a host(161) are passed by the interface device(131) and received by a receiver(103). If the command data is a print command, the print mechanism(108) prints the specified text or image. If the command data is a command for updating the operating parameter data, the corresponding data in the memory(109) is updated and at an appropriate backup timing the data in the memory(109) is copied to memory(135) in the interface device(131). The data backed up to the interface device(131) can then be restored to memory(109) in the printer from the memory(135) in the interface device at an appropriate data restore time.
