Input Buffer - Lexmark T430 Technical Reference

For information on installing a print server in your printer, see your printer
documentation.
You may also connect your printer to a LAN by using an external print server. Use one
of the following:
Note:

Input Buffer

Your printer has an input (link) buffer for each interface. The maximum size of the input
buffer depends upon the amount of RAM memory installed. The input buffers serve
the same purpose as a print spooler and can be allocated automatically by the printer.
The size of the input buffer may be modified or disabled from the operator panel
menus or through MarkVision Professional.
If NPAP is active on a port, two-thirds of the buffer memory is reserved for NPAP and
one-third is set aside for the input buffer. If NPAP is not active, all the memory is
available for the input buffer.
Table 8-8 shows the sizes automatically selected for the buffers when the buffer size
is set to
