PrinterJob.printDialog() allows you to request more than one copy collated.
This doesn't (and shouldn't) work with Printable's, so the request shouldn't be
allowed.

Note: If you request 2 copies, collated, JDK 1.4 beta produces 2 copies,
uncollated. JDK 1.3 produces 1 copy. Both JKD's have the correct behavior if
you do not request collated.

  Program exhibiting this behavior follows (taken from sec. 7.3.2 of:

     // Specify the Printable is an instance of
     // PrintListingPainter; also provide given PageFormat
     job.setPrintable(new PrintListingPainter(args[0]), pf);
