A usage control apparatus and a device in a fee system for a device are provided. The usage control apparatus and the device allow to charge depending on usage without having to access a server 20 during use. An issuing module 21 of server 20 collects payment from a client 30, and issues a predetermined amount of money information 51. When client 30 uses a printer 40 or other device, it appends to the print data 52 the money information 51 required for use (here, for printing), and sends it to the printer 40. If money information 51 in the amount required for printing is transmitted to the printer 40, it performs printing.
