Abstract

PURPOSE:To make it possible to verify the propriety of a printer response output according to a diagnostic program provided in a host machine, by transferring control data for a printer device to and from the host machine, comparing logical mechanism control data on the printer device with mechanism control data sent from the host machine, and displaying the comparison results. CONSTITUTION:In response to an input instruction signal from a comparator 6, an I/O controlling part 1 outputs an input demand signal to a host machine 10. When diagnostic data 102 corresponding to control commands for a printer device 20 is sent from the host machine 10 to a simulator 2, the simulator 2 starts the printer device 20, and sends mechanism control data obtained from the printer device 20 to a buffer memory 4. Also, the simulator 2 analyzes the diagnostic data, and sends the mechanism control data conforming to the functions of the printer device to a simulation memory 3. Then, the comparator 6 reads the data stored in the simulation memory 3 as reference data, reads the data stored in the buffer memory 4 as sample data, and compares both of the data with each other. When both of the data do not coincide, the comparator 6 outputs a signal to a diagnosis display part 7, and sends an input instruction signal 110 when a verification signal relevant to the outputted signal is sent back thereto.
