Host Requirements 
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 
network controller, see the reference manual for the controlling device.

Communications Interfaces 
The printer supports serial communications with the following interfaces: 
• RS-232 
• RS-422 
• RS-485 
The following sections describe these interfaces. See the Data 
Communications Reference Manual
 (P/N 044737) for more detailed 
information. 
RS-232 Serial Interface 
Use the RS-232 serial interface in all asynchronous point-to-point full- or 
half-duplex direct data communications or modem control. The printer 
cable must have the pin assignments for an RS-232 serial interface shown 
in the next table.
