Technical Specifications
STROBE pulse to read data in. Pulse
width must be more than 0.5 µs at the
receiving terminal.
These signals represent information of
the 1st to 8th bits of parallel data,
respectively. Each signal
when data is logical 1 and LOW when it
logical 0.
Approximately, 12 µ
LOW indicates that data has been
received and that the printer is ready
to accept more data.
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 2-4 to ON.)
Unused.
