LocalTalk Menu Selections
Menu Item Values and Functions of the Menu Items
NPA Mode Off
Auto*
NPA is a mode of bidirectional communication that follows the 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 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 LOCALTALK MENU only applies to the
LocalTalk interface connection.
Note: Changing the NPA Mode setting automatically resets the printer.
LocalTalk Buffer Disabled
Auto*
6K to maximum size allowed
You can configure the size of the LocalTalk 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 available for modification depends on the amount of
memory in your printer, the size of the other link buffers, and if the
Resource Save setting is On or Off. To maximize the range for the
LocalTalk Buffer size, you can disable or reduce the size of the parallel,
serial, network, and Infrared buffers.
Choose Auto to let the printer calculate the buffer size proportional to the
total amount of available printer memory. In most cases, Auto is the recom-
mended setting.
Note: Changing the LocalTalk Buffer setting automatically resets the
printer.
NPA Hosts 1
2*
3 ... 10
Use this setting to specify the maximum number of NPA hosts that can
register for NPA printer alerts. When the number of hosts registered for
NPA alerts exceeds the quantity specified by the NPA Hosts menu item,
any additional hosts attempting to register for alerts are ignored.
Note: Changing the NPA Hosts setting automatically resets the printer.
