4–2 Printer 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. The printer interface consists of a printed
circuit board assembly (PCBA) and a cable connector for the data line.
Communication signals and data may be sent over parallel or serial lines.
The printer is equipped with two parallel interfaces and a serial interface.
Only one interface can be used at a time, and it is selected via control panel
configuration. (Refer to Chapter 3, Configuring the Printer.) Only one
parallel host computer can be connected to the printer at a time.
The Coaxial/Twinaxial option is available as a factory-installed or
field-installed option. This option allows the printer to emulate IBM 3287,
5225, and 4234 printers. Contact your authorized service representative for
details.
