Signal Description
1 In
Strobe
†
[nStrobe]
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.
2 In
Data 0 [Data 1] These eight signals form one byte of data sent from host
computer to printer. Data 7 [8] is the most significant bit.

10 Out Acknowledge
†
[nAck] This negative-going pulse acknowledges the previous
character received.
11
Out Busy [Busy]
When this signal is high, the printer is busy. When it is low,
the printer is able to receive more data.
12
Out Paper Empty
