While I agree that it isn't preferable to run an IPP service (CUPS) at some
port other than 631, It shouldn't break interoperability.  The PAPI, CUPS,
and Windows implementations of client side support will all let you direct
your IPP connection to whichever  port your like.  I woudl be surprised if
that weren't true of other implementations.

The fact is, I have a system with Solaris LP listening on 631 and
CUPS listening on a different port for PAPI/IPP testing and results
comparison.
