Section 3: Interface Specifications

IEEE1284 PARALLEL INTERFACE

The parallel interface for the M-84PRO printers is a Plug-In Interface Module that can be installed
by the user. It 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 bi-directionally and can report the
status of the printer back to the host.
