ABSTRACT:
A printer receives image information from a host computer and performs printing based on the image information. When an optional unit is newly attached to the printer, the printer changes the device ID which is selected from an ID ROM in accordance with the optional unit. Then output from an interface circuit is changed so that the host computer detects the change of the output from the interface circuit. The host computer makes a device-ID request to the printer to obtain the device ID corresponding to the optional device. Then the host computer determines whether or not a printer driver which is currently operative corresponds to the printer with the newly-attached optional device.
