Thankfully, the problem isn't in lpd, it's in chkprintcap.

Works like a charm here - we have about 15 aliases for the same
printer (simplex, duplex, input bins, output bins, staple, etc).
There may be some danger in doing this, but we haven't really run in
to problems with it. (*)

(*) - we do have a problem whereby two jobs for different settings of
the printer can end up shifting the input/output bin of the other job.
I haven't bothered to look in to it yet to figure out if it's because
of the spool directory; I think it's instead a problem with our
printer setup script.
