ABSTRACT:
An image forming system includes a printer main body and optional units coupled thereto through a serial communication line. Each of the optional units has its own device identification code. The printer system main body includes a table memory for storing logical identification codes each of which is assigned one of the device identification codes. Each of the optional units includes a memory for storing its own device identification code and the logical identification codes which has been assigned to its own device identification code, and a discerning circuit for discerning whether one of the logical identification codes sent from the printer main body is identical to its own assigned logical identification code stored in the memory. The printer main body receives paper from one of the optional units related to one of the logical identification codes sent by the printer main body, and ejects paper to one of the optional units related to one of the logical identification codes sent by the printer main body.
