Chapter 3: Using the Operator Panel and Menus
NPA Mode 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 INFRARED MENU applies only to the infrared interface
connection.
Note: Changing the
NPA Mode setting automatically resets the printer.
Infrared Buffer Disabled
Auto*
5K to maximum size allowed
You can configure the size of the infrared 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
software application each time you send a job to the printer, you may want to increase the
buffer size.
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 infrared buffer size, you can disable or reduce the size of the
parallel, serial, LocalTalk, and 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
Infrared Buffer setting automatically resets the printer.
Window Size Auto*
1
The Window Size setting specifies the maximum number of infrared frames the printer can
receive before it must send an acknowledgment to the host computer.
Select
Auto to let the printer automatically set the window size during a power on reset to
maximize link performance.
In most cases,
Auto is the recommended setting. If you have trouble printing using the
infrared port, changing the
Window Size setting to 1 may resolve the problem.
