This is how Qt4 treats the issue - it's entirely client-side.  KPrinter 
allows the application to either volunteer to do the page selection 
itself or get the print system (only works with CUPS) to do it.

This isn't really an issue - I think it's entirely reasonable to expect 
the client to do the page selection.  However, Qt4 doesn't allow you to 
select arbitrary page lists in the print dialog.  They must be selected 
in the application before hand, and the user has to choose "selection" 
in the print dialog box.
