Job buffering is disabled. Any jobs
already buffered on the hard disk are
printed before normal processing of
incoming jobs resumes.
The MFP automatically calculates the
USB Buffer size (recommended
setting).
The user specifies the USB Buffer
size. The maximum size depends on
the amount of memory in the MFP, 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.
Does not buffer print jobs to the hard
disk.
Buffers print jobs to the hard disk.
Buffers print jobs only if the MFP is
busy processing data from another
input port.
The MFP filters PostScript print jobs
using standard protocol.
The MFP processes raw binary
PostScript print jobs from computers
using the Macintosh operating system.
Note: This setting often causes
Windows print jobs to fail.
The MFP processes print jobs from
computers using either Windows or
Macintosh operating systems.
