Description

The STROBE pulses to read

data. Pulse width must be more
than 0.5 µseconds at the
receiving terminal.

These signals represent data in

bits 1 to 8 of parallel data,

respectively. Each signal is high
when data is logical 1 and low
when it is logical 0.

About a 12-µseconds pulse.
Low indicates that data has
been received and that the

interface card is ready to accept
more data. This signal is output
paired together with a BUSY
signal.

A high signal indicates that the

interface card cannot receive

data. The signal goes high in

the following cases:
1) During data entry (along

with each character)

2) When OFF LINE

(or PAUSE)

3) During printer-error state

A high signal indicates that the
printer is out of paper.
