Job Buffering
Purpose:
To temporarily store jobs on the printer hard disk before printing.
Using the printer menus
Job buffering is disabled. Any jobs already buffered on the disk are
printed before normal processing of incoming jobs resumes.
Printer automatically calculates the USB Buffer size (recommended
setting).
User specifies the USB 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 USB Buffer size, disable or reduce the size of the parallel, serial,
and network buffers.
