A printer determines in S11 to S15 whether any device connected to the network is the same type of device. Then the printer determines which of these same type devices have firmware older than firmware of the printer (S23). With respect to each device with older firmware (S23:YES), the firmware of the device is rewritten in S27 based on the firmware of the printer. As a result, the firmware of devices connected to the network can be easily rewritten. All other devices that are the same type as the printer can have their firmware updated into a firmware at least as new as the version stored in the printer. Accordingly, labor required to manage the network system can be greatly reduced.

The present invention provides a storage device that enables identification data to be readily rewritten and ensures normal completion of a data writing operation in a short time period. In the storage device of the invention, an ID comparator determines whether or not identification data transmitted from a host computer coincides with identification data stored in a memory array. In the case of coincidence, the ID comparator sends an access enable signal EN to an operation code decoder. The operation code decoder analyzes a write/read command, switches over a direction of data transfer with regard to the memory array based on a result of the analysis, and requires an I/O controller to change a high impedance setting of a signal line connecting with a data terminal DT. This series of processing allows access to an address in the memory array specified by a count on an address counter.
