[Content] The Centronics port is checked by connecting a special connector which connects
the Centronics port output and input signal wires to each other, to the Centronics
port of the PRT board. Whether the input signal is turned ON/OFF or not is
checked by turning the output signal ON/OFF. Checking is repeated 10 times. If
there is no error, OK is displayed; if there is any error, NG is displayed.
