This section describes the parallel interface (centronics/IEEE1284-compliant interface).
Shape of the connector
The printer is installed with the IEEE1284-B type of interface. The shape of the connector is as
follows:

The pin arrangement of the various signals when bidirectional is OFF is as follows:
●
Looking from the printer, "I" is the input signal, "O" is the output signal, and "-" is not a signal.
●
When bi-directional is Enable, the connection adheres to the IEEE1284-B connector standard.
