A network system for operating multiple printers in different locations includes an RFID tag or print information that is arranged at a location where the printer is used and stores location information for identifying the location. The system further includes a printer provided with location information read capability for electromagnetically reading the location information stored in the RFID tag or optically reading the location information stored in the print information. The system associates the read location information with a network address and assigns the associated network address to the printer that has the location information.
