You can configure the size of the serial input buffer to meet the
requirements of your system. If the limited size of the input
buffer is preventing you from continuing work in your application
each time you send a job to the printer, you may want to
increase the buffer size.
The maximum size depends on the amount of memory in your
printer, the size of the other link buffers, and whether the
Resource Save setting is set to On or Off. To maximize the
range for the Serial Buffer size, you can disable or reduce the
size of the parallel, infrared, LocalTalk, and USB buffers.
Choose Auto to let the printer calculate a buffer size propor-
tional to the total amount of available printer memory. In most
cases, Auto is the recommended setting.
Note: Changing the Serial Buffer setting automatically resets
the printer.

Job Buffering temporarily stores jobs on a hard disk option
before being printed, usually freeing the host computer while
the job prints.

If Job Buffering is set to On, print jobs are buffered to the hard
disk option. If Job Buffering is set to Off, print jobs are not
buffered.
Note: Changing the Job Buffering setting automatically resets
the printer.
