About the Parallel Port
The system provides one IEEE 1284-compatible, bidirectional parallel port for
connecting the system to a local printer or other compatible parallel device.
Connectivity is provided by a standard 25-pin DB-25 connector on the rear panel
of the system. The parallel port operates at a 2-megabytes per second data transfer
rate and supports the EPP protocol modes as well as standard Centronics, Nibble,
and Byte modes.
See “Reference for the Parallel Connector” on page 416 for the connector diagram,
rear panel icon, and pin assignments.
