Either run rawhide or use builds from
http://jpopelka.fedorapeople.org/cups-1.6/
which is what I run here on F18.

No

'How to test' needs to be enhanced, yes.

These instructions are still valid with cups-1.6 & cups-filters.

What UI do you have in mind ? system-config-printer ?

Maybe later when we have 1.6 in all releases. I don't see a reason at 
the moment. The example there is just an example and what filters are 
run depends on the PPD.

Not sure what you mean with "Fedora's". The print dialogs we use on 
Fedora are part of GTK/QT and therefore are used on Ubuntu too.
