Ieee1284 Parallel Interface - SATO CT 408i Operator's Manual

IEEE1284 PARALLEL INTERFACE

The parallel interface is a plug-in module that can be installed by the user and conforms to
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.
