Two printers/one queue

The 4.3BSD print spooler subsystem and the S5 print spooler subsystem
differ so much that there are no such entities as printer groups in the
4.3BSD print spooler subsystem.

With the 4.3BSD print spooler subsystem you do, however, get built-in
support for printing to printers attached to other machines.  (I.e.,
it's not some gross hack wrapped around UUCP, or something equally
horrid.)

If you get S5R4, you get both, at least according to the documentation;
the documentation claims that the daemon on one machine can talk to a
daemon on another machine using either some native S5R4 protocol or the
protocol used by the BSD spooler (although at times they misleadingly
speak of the SunOS spooler - the latter is based on the BSD one and
didn't change the protocol, so I'd expect the S5R4 spooler to be able to
talk to any BSD-flavored "lpd").
