Parallel Interface
Communication Modes
The printer provides high-speed data transmission on a parallel interface.
You can select the parallel interface communication mode from the
operation panel. To change communication mode, refer to
Changing
Parallel Interface Mode on page 2-30
.
NOTE:
Use a parallel interface cable that complies with the IEEE 1284
standard.
You can choose from four communication modes:
Interface Signals
Table shows the connector pins and corresponding input and output
signals of the parallel interface. Explanation of each signal is also given in
the table.
The description in [ ] indicates signal names in Auto mode and Nibble
(high) mode (IEEE 1284-compliant). In Auto and Nibble modes, these
signals are bidirectional.
