Interfacing Information

A. Introduction

B.CENTRONICS- type Parallel Interface

Depending on your operating environment, the PrimeraPro Color Printer is equipped with either a standard 8-bit Centronics-type parallel data communications port for use with a PC or an Amiga, or an Apple LocalTalk port for use with a Macintosh. These communication ports are the means by which the printer receives data from your computer. This section describes the pin assignments, protocol, and signal specifications for both the parallel data input port and the LocalTalk port.

The Centronics-type parallel interface is the most widely used printer interface due to its simplicity, speed and standardization throughout the PC industry. The printerÕs parallel interface connector is a standard 36-pin Amp type with two metal-wire retaining clips. It mates with a standard PC to printer parallel cable. Always keep the interface cable under 15 feet in length if connecting to a PC or under 6 ft. in length if connecting to an Amiga.

Pin assignments are as follows:

19 PIN 1

36 18
