IEEE1284 PARALLEL INTERFACE
The parallel interface is a plug-in module that can be installed by the user and conforms to
IEEE1284 specifications. It automatically detects the IEEE1284 signals and operates in the high
speed mode. If the IEEE1284 signals are not detected, it will operate in the slower standard
Centronics mode. For this reason, an interface cable and host interface conforming to the
IEEE1284 specification must be present to fully utilize the speed capabilities. This interface also
operates bi-directionally and can report the status of the printer back to the host.
