Parallel Interface

Detailed descriptions of the signals follow.
Strobe* [nStrobe] (Pin 1)
A negative-going Strobe* pulse causes the printer to read and latch the
data on the Data 0 [1] to Data 7 [8] signal lines.
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 has received a print job and run out
of paper.
Select [Online] (Pin 13)
This signal is high when the printer is online and low when the printer is
offline. It goes low when the
GO
key is pressed to set the printer offline.
+5 V DC (Pin 18)
This line is connected to the printer’s +5 V DC line (+5 V ±0.5 V, maximum
400 mA, fused).
Error* [nFault] (Pin 32)
When the high-speed parallel line control is on (FRPO O2=2), this line
returns error status.
Power Ready (Pin 35)
This signal is high when the printer is turned on.
The Paper Empty, Online, and Error signals are not used unless enabled
by the FRPO command (O2 parameter).
