Your printer has the following hardware and software requirements:
• The host computer must use the American Standard Code for
Information Exchange (ASCII) for data communications.
• A serial port must be available on the host if you are connecting directly
to the printer.
• The host must support at least one of the following data
communications interfaces: RS-232, RS-422, or RS-485.
For information on configuring the host computer, port concentrator, or
