Patent ID: 8147021

Claim:
A printing device for printing on a print medium, comprising: a printing module that prints an image onto a print medium by using a cartridge that contains a colorant, and for which cartridge is set a number of sheets guaranteed for printing, the number of sheets guaranteed for printing representing an upper limit of sheets that can be printed; a notification module that notifies information on a number of sheets remaining that can be printed with the cartridge; and a control module that prevents the printing module from printing with the cartridge when a number of sheets printed by the printing module has reached the number of sheets guaranteed for printing, and causes the printing module to print an image onto the print medium with the cartridge when the number of sheets printed has not reached the number of sheets guaranteed for printing, the control module determining the number of sheets remaining by subtracting the number of sheets printed from the number of sheets guaranteed for printing and causing the notification module to notify information on the thus determined number of sheets remaining.
