C.1. Parallel Interface
Appendix C
Host Computer Interface
This appendix describes the signals used in the laser printer's parallel, RS-232C/RS-
422A interfaces. It also lists pin assignments, signal functions, timings, connector
specifications, and voltage levels. The RS-232C/RS-422A protocols are also covered.
Finally, it explains the use of the printer in a multi-computer environment.
C.1.

Parallel Interface

Parallel interface communication modes

The printer features fast data transmission on the parallel interface. The parallel interface mode can be acti-
vated from the printer's control panel (see Chapter 2, Operating the Page Printer) as follows:
Use a parallel printer cable that complies with the IEEE1284 standard.
Nibble (high)
High speed data communication is used in compliance with the IEEE 1284 standard. Ordinarily, you should
leave this setting unchanged.
Auto [default]
The printer automatically changes its communication mode to the one the host computer is currently using.
Normal
The printer uses the communication method discribed by to the normal definitions of the Centronics inter-
face.
High-speed
This mode enables faster data transmission between the printer and the host computer. (Select this mode if
printing problems occur when the printer is connected to a workstation.)
