INTERFACE INFORMATION

This printer can communicate with a computer

through a Centronics parallel interface,

a RS-232C serial interface, a USB interface, or a LAN interface. You can

specify the interface selection mode so that the printer uses which interface or

it can automatically select the interface from which it first receives data.

This appendix provides information you may need for wiring your own

interface cables or for programming computer-to-printer communications.

Most users do not need the information in this appendix. To simply connect

your printer to your computer, follow the instructions in Chapter 2.

This parallel interface can operate in the following two modes:

Unidirectional (forward channel) mode or conventional mode: This

printer supports a conventional Centronics interface.

Bidirectional (forward/reverse channel) mode or nibble mode: This

printer supports a bidirectional communication per Nibble mode of the

IEEE 1284 Standard.

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 following tables by modes. In

the tables:

“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).
