Lexmark 1200 manual NPA Mode Off Auto, Connection

LocalTalk Menu (continued)

Menu item		Values
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 On, the data
		received must be in NPA format. If not, it is rejected as bad data. If NPA Mode is set 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 applies only 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 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 On or Off. To maximize the range for the
		LocalTalk Buffer size, you can disable or reduce the size of the parallel, serial, fax, network,
		and infrared buffers. Choose the Auto setting to let the printer automatically calculate a buffer
		size proportional to the total amount of available printer memory. In most cases, Auto is the
		recommended setting.
		See page 67 for a listing of the default buffer sizes for all the interface ports.
		Note: Changing the LocalTalk Buffer setting automatically resets the printer.
Job Buffering	Off*
		On
		If you have an optional disk installed in your printer, you can choose to have jobs that are sent
		to the LocalTalk port spool to the disk. Spooling jobs to disk may decrease the time required
		for the printer to accept data from an application, and therefore free the application faster for
		other work. Since disk memory provides permanent storage, job buffering to disk also
		prevents the loss of print job data if the printer loses power.
		The Job Buffering menu item is not displayed if the formatted hard disk is defective, is Read/
		Write or Write protected, or if Job Buffer Size is set to Disabled in the Setup Menu.
		See page 68 for more information about job buffering.
		Note: Changing the Job Buffering setting automatically resets the printer.
