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.
