Output method and apparatus using the same
 An output apparatus such as a printer is controlled by a control program. A first control program is stored in a fixed storage medium, and a second control program having a different operation than the first control program is stored in a detachable storage medium. The two control programs are selectively used, based on data received from a host computer.
