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.

X-ON/X-OFF CABLE REQUIREMENTS

Communicates with the host to determine if the printer is ready to receive data by sending “XON” (HEX 11H) or “XOFF” (HEX

13H) code to the TD line. The single and multiple item buffers are switchable in the Interface Mode of the printer.

NOTE: Depending on the host used, it may be required to loop CS and RS

(maintaining at high-level) on the host side. For more information, refer to the host

computer documentation.

NOTE: Refer to the Charts & Diagrams unit of this manual to view timing charts for

Ready/Busy and X-ON/X-OFF.
