Parallel Mode 1
Purpose:
To control the pull-up resistors on the parallel port signals. This menu item is useful for personal
computers that have open collector outputs on the parallel port signals.
Values:
On Printer performs NPA processing. If data is not in NPA format, it is rejected as bad data.
Off Printer does not perform NPA processing.
Auto* Printer examines data and determines the format and then processes it appropriately.
Disabled Disables serial (Parallel, USB) port. Any jobs already buffered on the disk are
printed before normal processing of incoming jobs resumes.
Auto* Printer automatically calculates the Parallel Buffer size (recommended setting).
3K to maximum
size allowed
User specifies the Parallel Buffer size. The maximum size depends on the
amount of memory in your printer, the size of the other link buffers, and
whether Resource Save is set to On or Off. To maximize the range for the
Parallel Buffer size, disable or reduce the size of the serial and USB buffers.
On Disables the resistors.
Off* Enables the resistors.
