Does there happen to be a demo online? and if so: could you give us a
demo account where we can play a bit? :)

that means CUPS also knows about the proper ppd file when a printer is
connected to a computer (plug-and-play)?

is there a special reason why they have to be selected manually?
and how many optional accessors may that be (max number in a high-end user)?

sure, next step ;-)
but the classic printing roles basically cover all the tasks that need
to be performed, no? The reason I ask is that we still need to get clear
about the possible task space before thinking of concrete use scenarios,
just to make sure we do not forget anything..
