PROBLEM TO BE SOLVED: To limit a use of a toner cartridge by a user other than a registered user by comparing an identifier of the designated user with the identifier read from a storage means. SOLUTION: Firstly, it is judged whether or not the data received is the command which designates a user identifier. If the user identifier is the designated command, it is judged whether or not the designated identifier is registered, by retrieving it from the table which registers the user identifier in NVRAM 2012. And if the designated identifier is registered as a result of this judgment, a flag which shows to permit printing in RAM 2002 is made to a print permission state, and if not registered, an error processing such as displaying it on an operation panel 1012 or informing a host computer of it, etc., is performed. Thus, a fine control can be performed with respect to print processing. |
