Introduction

This chapter describes the communication interfaces and provides information about their use with your printer.

The communication interface transfers data in a fixed and orderly manner between the host and the printer. Communication interfaces are of two general types: parallel and serial. Parallel interfaces transfer all bits of a data byte simultaneously. Serial interfaces transfer data in bit-serial fashion, one bit at a time.

To provide communication compatibility with a wide range of systems, your printer offers a choice of any of the following standard and optional communication interfaces.

qParallel interface, standard.

qRS-232 or RS-423 serial interface, standard.

qRS-422-A serial interface, optional.

qCurrent loop (TTY) interface, optional.
