Abstract
An object of the present invention is to simplify management of the amount of recording agent used by multiple users, by allocating a recording agent cartridge to a user in advance. In a printing device of the present invention, a primary user and a secondary user are set as active user information for each of multiple recording agent cartridges in a printing device connected to a network. When a print job with user identification information is received via the network, the printing device specifies a cartridge of which the primary user is the user who sent the job, based on the user identification information and the active user information, and determines whether the residual amount in the specified cartridge is sufficient (S). When the residual amount is not sufficient, the procedure specifies another cartridge for which the user is set as the secondary user, based on the user identification information and the active user information, and set the specified cartridge as a active cartridge to be used for printing (S).
