Abstract
A printer 240 calculates the amount of ink used only for printing as a number of discharged ink shots, and sends this shot count with the printer serial number and ink cartridge ID to a server 220. The server 220 saves the shot count, printer serial number, ink cartridge ID, and an error correction code as status information. The server 220 or server upstream from the server 220 can reliably determine the number of ink shots used by the printer 240 only for printing from this status information.
