It will certainly use more of your bandwidth, however my experience
has been that network printers rarely have the speed to saturate a
typical 100baseT connection.  Either the file will be relatively
small and the print engine won't be able to print fast enough to
saturate the link, or the processor in the printer won't be fast
enough to process the larger page descriptions and get them to the
engine for printing.

That said, it might make sense to use a separate network segment if
you have a lot of printers, as multiple printers *can* collectively
use up all of your bandwidth.
