Interfacing Information
A.Introduction
B.Centronics- type Parallel Interface
The Color ID Card Printer is equipped with a standard 8-bit Centronics-type parallel data communications port. This is the means by which the printer receives data from your computer. No options for serial data are available. This section describes the pin assignments, protocol, and signal specifications for the parallel data input 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 and is ECP (Extended Capabilities Port) compatible. It mates with a standard PC to printer parallel cable. Try to keep the interface cable to under 6 feet if possible.
Pin assignments are as follows:
