INTERFACE INFORMATION
This printer can communicate with a computer
through either a Centronics parallel interface or
an RS-232C serial interface.
This appendix provides information you may need for wiring your
own interface cables or for programming computer-to-printer commu-
nications. Most users do not need the information in this appendix. To
simply connect your printer to your computer, follow the instructions
in Chapter 2.
The Centronics interface is the industry-standard parallel interface.
The cable connector at the printer side should be a shielded,
Amphenol DDK 57FE-30360 or equivalent.
The connector pin assignments are given in the table that follows. In
the table:
•“Input” denotes a signal from the computer to the printer.
•“Output” denotes a signal from the printer to the computer.
•The return lines specified in the second column represent
twisted pairs, with one side connected to signal ground.
•The standard signal levels are 0.0 to +0.4 V (low), and +2.4 to
+5.0 V (high).
