Appendix B: Interfacing Information

I. INTRODUCTION
The Quatro 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 chapter describes
the pin assignments, protocol, and signal specifications for the
parallel data input port.
II. 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 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 shielded, bi-directional PC to
printer parallel cable. Try to keep the interface cable to under
6 feet if possible.
Pin assignments are as follows:
