Abstract

PURPOSE:To discriminate the type of a printer with respect to software by sending a test command from a host machine to the printer and detecting an acknowledgement signal while retrieving the occurrence of a fault signal in a loop. CONSTITUTION:First, command initialization is performed to send the test command to a printer 2. When sending of this text command is started, a loop counter is set to decide whether the fault signal occurs or not. If the fault signal is detected, the printer is discriminated as a page printer in accordance with the status of the printer. On the other hand, if the fault signal is not detected and the loop ends, it is decided whether the acknowledgement signal is detected or not, and the printer is discriminated as a dot printer in accordance with the status if this signal is detected.
