15 Interfaces

Overview

The printer interface is the point where the data line from the host computer plugs into the printer. The interface processes all communications signals and data to and from the host computer. It consists of a printed circuit board assembly (PCBA) and a connector for the data cable from the host computer. Communication signals and data may be sent over Ethernet, parallel, or serial lines.

When data is sent through multiple interfaces, the Autoport Switching feature forces the printer to automatically switch between the serial and parallel port and between the Ethernet adapter and the serial port when NIC is installed.

This chapter describes the following interfaces:

Centronics

Bi-Tronics

RS-232 serial

RS-422 serial

Note

To determine which interface is installed on your printer, refer to Table 1 on

 

page 19. If you require a parallel interface and it is not installed, contact

 

your authorized Printronix representative.
