Probably these should go in a separate subdirectory under Source.

Best would be to check automatically in configure if CUPS is present, 
and use the classes if it is. Perhaps we need an LPR class that would 
handle printing otherwise (or perhaps the CUPS classes could be written 
so they can be used with and without CUPS - I don't really know how 
they work).

It would be nice then if NSPrinter/etc was rewritten to use whichever 
class was available.
