SECTION 5: INTERFACE SPECIFICATIONS

5.3 IEEE1284 PARALLEL INTERFACE

The parallel interface for this printer conforms to the IEEE1284 specification. It will
automatically detect the IEEE1284 signals and operate in the high speed mode. If it does
not detect the IEEE1284 signals, it will operate in the standard Centronics mode, which
is significantly slower. 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 bidirectionally and can report the status of the printer back to the
host.
