If the printers are the same and the paper trays have the same paper
then automatic switching could be used (a "printer pool").

If the printers or paper aren't the same, automatic switching would be
difficult. As far as I know the external automatic switch has no way to
tell the application which printer will be used, so they can't cooperate
and choose an acceptable printer-paper combination (Steven Levine has
mentioned MarkVision and Jet Direct but I don't know what these products
are capable of). And once the application chooses a printer with its
associated driver, the output can't then be routed to a printer with an
incompatible control language; even printers as similar as my LaserJet
II's and IID's can't exchange print jobs.

I use multiple printer objects, one for each "type" of print job, and
spool all my printouts. The spoolers are always kept on "processing
held" status and I release the spoolers one at a time for printing.
Each printer/spooler object is shadowed to my Warp Center so doing this
is easy.
