No - I'm not gonna parse your cups.conf but I'm sort of wondering if
there is a cupsd.conf.rpmnew that is considerably lighter than the one
that's in use. That's what I noticed - that cupsd.conf went on a
diet...I think it was in F8 but I could be wrong - memory fails me...but
I do recall at some point, I moved out my old cupsd.conf and moved in
the rpmnew version and things were simpler and worked better. Seemed to
be one of the things that didn't migrate over the Fedora version upgrade
churns all that well.
