NPA Mode On
Off
Auto*
NPA is a mode of bidirectional communication that follows the conventions defined in
Network
Printing Alliance Protocol, A Printer/Host Control Specification Developed by the NPA
.NPA
mode requires special processing of the print data.
If
NPA Mode is set to On, the data received must be in NPA format. If not, it is rejected as bad
data. If
NPA Mode is set to Off, the printer does not perform any NPA processing. If NPA Mode
is set to Auto, the printer examines the data to determine the format and then processes it in
either format.
The
NPA Mode setting in the PARALLEL MENU applies only to the parallel interface
connection.
Note: Changing the
NPA Mode setting automatically resets the printer.
Parallel Buffer Disabled
Auto*
3K to maximum size allowed
You can configure the size of the parallel input buffer to meet the requirements of your system.
The maximum size available for modification 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, you can disable or reduce the size of the serial,
network, infrared, LocalTalk, and Universal Serial Bus (USB) buffers.
Choose
Auto to let the printer calculate a buffer size proportional to the total amount of
available printer memory. In most cases,
Auto is the recommended setting.
Note: Changing the
Parallel Buffer setting automatically resets the printer.
Job Buffering Off*
On
Job buffering lets you delay processing of a print job. The job is temporarily stored on a hard
disk option before being printed, usually freeing the host computer while the job prints.
The
Job Buffering menu item only displays if the installed hard disk option is formatted and is
not
defective, Read/Write or Write protected, and if Job Buffer Size is
not
set to Disabled.See
Job Buffer Size on page 77 for more information. 61 Defective Disk may display when the
printer is turned on, or during disk format and write operations. See
61 Defective Disk on
page 165 for more information.
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.
