Abstract

See full text

There is provided a method of storing an initial use date of a printer and informing the initial use date. To store the initial use date, it is determined whether the printer is used for the first time. If the printer is used for the first time, the initial use date is stored in a storage of the printer. Thus, a repairman can easily estimate a guarantee period for the printer based on the initial use date stored in the storage of the printer.
