Description
A HIGH signal indicates that the printer
cannot receive data. The signal goes
HIGH in the following cases:
1) During data entry (ea. char. time)
2) During printing
3) When off line
4) During printer-error state
A HIGH signal indicates that the printer is
out of paper.
Pulled up to +5 V through 3.3 K
resistance.
When this signal is LOW, the paper is
automatically fed 1 line after printing. (The
signal level can be fixed to this by setting
DIP switch 2-3 to ON.)
Unused.
Logic ground level.
Printer’s chassis ground, which is isolated
from the logic ground.
Unused.
Twisted-pair return signal ground level.
When this level becomes LOW, the printer
controller is reset to its power-up state and
the print buffer is cleared. This level is
usually HIGH; its pulse width must be
more than 50 microseconds at the
receiving terminal.
This level becomes LOW when the printer is:
1) in paper out state.
2) off line.
3) in error state.
Same as for Pins 19-30.
Unused.
