Description

Sets the size of the parallel input buffer

Notes:

•Auto is the factory default setting.

•Disabled turns off job buffering. Any print jobs already buffered on the printer hard disk are printed before normal processing resumes.

•The parallel buffer size setting can be changed in 1-KB increments.

•The maximum size allowed depends on the amount of memory in the printer, the size of the other link buffers, and whether Resource Save is set to On or Off.

•To increase the maximum size range for the Parallel Buffer, disable or reduce the size of the USB, serial, and network buffers.

•Changing this setting from the printer control panel and then exiting the menus causes the printer to restart. The menu selection is then updated.

Temporarily stores print jobs on the printer hard disk before printing

Notes:

•Off is the factory default setting.

•On buffers print jobs on the printer hard disk.

•Auto buffers print jobs only if the printer is busy processing data from another input port.

•Changing this setting from the printer control panel and then exiting the menus causes the printer to restart. The menu selection is then updated.

Enables bidirectional communication through the parallel port

Notes:

•On is the factory default setting.

•Off disables parallel port negotiation.

Specifies the parallel port protocol

Notes:

•Fastbytes is the factory default setting. It provides compatibility with most existing parallel ports and is the recommended setting.

•Standard tries to resolve parallel port communication problems.

Determines if the printer honors printer hardware initialization requests from the computer

Notes:

•Off is the factory default setting.

•The computer requests initialization by activating the Init signal from the parallel port. Many personal computers activate the Init signal each time the computer is turned on.

Determines if the parallel port data is sampled on the leading or trailing edge of a strobe

Note: On is the factory default setting.
