Operator Manual

Parallel I/O Category

The Parallel Category on your printer has three parameters that can be changed according to user needs.

POPC (Print On Paper Command)

The POPC Parameter can be set up so that each time a paper advance command is received (such as a Line Feed, Form Feed, or Vertical Tab), any data currently held in the buffer will be printed before the command is carried out.

The default selection is On.

8th Bit

The 8th Bit can serve several functions, depending on the software manufacturer. Check your software manual for information concerning the functions of this bit. Data is the default selection.

Bi-Directional

This parameter controls the bidirectional operation of the Parallel interface. The default selection is ON (enabled).

When ON, the Parallel interface operates in IEEE-1284 Bidirectional Nibble

Mode. This mode enables features dependent on bidirectional "reverse channel" communication via the parallel port, such as HP PJL Status and Windows

Plug-n-Play. Note that the host computer or print server attached to the parallel port must be configured to use IEEE-1284 Nibble Mode, otherwise it may not function correctly with your printer. ECP Mode is not compatible with Nibble

Mode.

When OFF, the Parallel interface operates in the Centronics Compatibility Mode

("standard" mode). This mode does not support bidirectional communication. If there are parallel interface compatibility problems between the host computer and the printer, setting Bi-Directional = OFF may resolve the problem.
