Parallel Interface

Data 0 [1] to Data 7 [8] (Pins 2 to 9)

These eight signals form the data byte sent from the host computer to the

printer. Data 7 [8] is the most significant bit.

Acknowledge* [nAck] (Pin 10)

This negative-going pulse acknowledges the previous character received by

the printer.

Busy [Busy] (Pin 11)

This signal is high when the printer is busy and low when it is able to

accept more data.

Paper Empty [PError] (Pin 12)

This signal goes high when the printer runs out of paper.

Online [Select] (Pin 13)

This signal is high when the printer is online and low when the printer is

offline. It goes low when the upper unit is raised, or when the GO key is

pressed to set the printer offline.

The Paper Empty and Online signals are not used unless enabled by the

FRPO command (O2 parameter).
