A.5 Parallel Interface
This section describes the parallel interface (Centronics interface conforming to
the IEEE1284 standards) installed in this printer.
Connector Shape
The printer has an IEEE1284-B type connector. The connector shape is as follows:
Pin Arrangement
When both directions are OFF, the signal pin arrangement is as follows:
●
I/O indicates the direction from the viewpoint of the printer. field, I represents an input signal, O
represents an output signal, and Å| represents no signal.
●
When both directions are ON, the wiring conforms to the standard of IEEE1284-B type connector.
