Description
A HIGH signal indicates that the printer
is OUT of paper.
Pulled up to +5 volts through 3.3. K ohm
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 2-8 to on.)
Not used.
Logic ground level.
Printer's chassis ground, which is
isolated from the logic ground.
Not used.
Twisted-pair return signal ground level.
When this level becomes LOW for at
least 50 microseconds, the printer
controller is reset to its power-up state
and the print buffer is cleared. This level
is normally HIGH.
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.
Not used.
Pulled up to 5V through 3.3. K ohm
resistance.
The DC1/DC3 code is valid only when
this signal is HIGH. (Internal fixing can
be carried out with Jumper J1. The level
of this signal is factory-set to LOW.)
