In general, only the printer types would need to have any kind of  
reference counting, which greatly limits the amount of change you'd  
need.

That said, I'd much rather fix the actual bug instead of adding  
reference counting just for this one situation.  More than likely this  
would just mean removing all of the type and filter references before  
renaming; alternately, we can delay deletion of types and filters  
until the printer itself is deleted.
