Serial Buffer Disabled
Auto*
3K to maximumsize allowed
Youcan configure the size of the serial input buffer to meet the requirements of your system.
Ifthe limited size of the serial buffer is preventing you from continuing work in your software
application each timeyou send a job to the printer, you may want to increase the buffer size.
Themaximum size depends on the amount of memory in your printer, the size of the other link
buffersand whether the Resource Save setting is set to On or Off. To maximize the range for
the serial buffersize, you can disable or reduce the size of the parallel, infrared, LocalTalk,
andUSB buffers. Choose Auto to let the printer calculate a buffer size proportional to the total
amount of availableprinter memory. In most cases, Auto is the recommended setting.
Note: Changing the SerialBuffer setting automatically resets the pr inter.
