So am I correct in assuming that the files if shipped as part
of a distribution normally go into:

/usr/share/ppd
/usr/lib/drivers

If there is distro agreement here, we should get this put into the FHS
as well.

I'm not convinced that we need to add /opt/printing

The /opt/<vendor> technique should still work, and for convenience
symlinks can be created in /opt/share/ppd and /opt/lib/drivers to the
actual files. If you use LANANA, strictly speaking you could just
install straight into /opt/share and /opt/lib because you know there
won't be any clashes, but I'd still strongly recommend using symlinks
instead as it keeps the design simpler and consistent.

Of course, LANANA is still of use to ensure that you don't clashes
with the symlinks.
