lp/lpr interface

More or less.  The SunOS spooler is the 4.2BSD or 4.3BSD spooler (4.3BSD if
you're running 4.0); it does have the notion of "filter" programs, but it's
done differently.  The 4.xBSD one also has networking support built in; it's
nice to have "lpq", "lprm", etc. work over the wire as well as "lpr"
(especially since I have no printer attached to my machine).

If you have a UUCP that works over e.g. TCP on both sides; the current SunOS
one doesn't support TCP connections.
