Description
Logic ground level.
Printer's chassis ground, which is isolated
from the logic ground.
Unused.
Twisted-pair return signal ground level.
When level becomes LOW, the printer
controller is reset to its power-up state
and the print butter is cleared. This level
is usually HIGH; its pulse width must be
more than 50 µs at the receiving
t e r m i n a l
This level becomes LOW when the printer
is in:
1) Paper-end state
2) Off line state
3) Error state.
Same as for Pins 19 - 30.
Unused.
Pulled up to +5 V through 3.3 K
resistance.
The DC1/DC3 code is valid only when
this signal is HIGH. (Internal fixing can
be carried out with DIP switch pin 2-1.
The level of this signal is factory-set to
LOW.)
