Signals when data is ready to be read.Signal
IN goes from HIGH to LOW (for at least 0.5
microsec.) when data is available.
These signals provide the information of the
IN first to eighth bits of parallel data.Each signal
is at HIGH level for a logical 1 and at a LOW
level for a logical 0.
A 9 microsecond LOW pulse acknowledges
OUT
receipt of data.
When this signal goes LOW, the printer is re-
ady to accept data. When the printer is in one
OUT of the conditions below. " HIGH" is set.
1. Data being entered.
2. Off line.
3. Error condition.
OUT This signal is normally LOW. It will go HIGH
if the printer runs out of paper.
OUT This signal is HIGH when the printer is online.
Unused
Signal ground.
Chassis ground, isolated from logic ground.
This pin is pulled-up 4.7 k W resistor to +5V.
Twisted pair return signal ground level.
When this signal gose LOW, the printer is reset
IN
to its power-on condition.
This signal is normally HIGH. This signal go-
es LOW to signal that the printer cannot print
OUT
due to an error condition.
Refer to Item 7-6 Emergency Suspension.
