Parallel interface connector (printer side)
This connector mates with an
Amphenol 57-30360 connector
Appendix C: Parallel Interface
The two-way parallel interface is compatible with the IEEE1284 compatibility mode
and nibble mode. Refer to the separate Specification Manual for details.

Note:
1) The first letter “n” of each signal name indicates that the signal is active
“L”. If any one of the above signals is not available, bidirectional commu-
nication cannot be accomplished.
2) In interfacing signals, be sure to use twist-paired wires for signal lines, and
the return side must be connected to signal ground level.
