9.1 Proposal: Printing support

[Jim Gettys]

This worked (discovery) at one point (I tried it very early in OLPC
days).

But printer discovery is better done by some other mechanism than that
defined in IPP anyway, which is stupid broadcast.  Even MDNS is less
evil (e.g. avahi).

Some work is probably needed for scaling of printer discovery.

Running a cups server is almost certainly not necessary, though its
footprint might not be too terrible if it is stripped of all the stupid
printer definitions (which are huge).  I haven't tried that experiment.
