Appendix A: Interfacing Information
A. INTRODUCTION
The CD Color Printer is equipped with both a standard 8-bit centronics-type parallel interface port and a high-speed serial interface port. These communication ports are the means through which the printer receives data from your computer. This section describes the pin assignments and signal specifications for each of these ports as well as for the printerÕs auxiliary interface port.
B. CENTRONICS-TYPE PARALLEL INTERFACE
The Centronics-type parallel interface is the most widely used printer interface due to its simplicity, speed, and standardization throughout the computer industry. The printerÕs parallel interface connector is a standard 36-pin Amp type with two metal-wire retaining clips. It mates with a standard computer to printer parallel cable. For best results, always use a shielded, bidirectional parallel cable which is less than 6 feet in length.
Pin assignments are as follows:
