A lot of sites have printer-friendly pages that are lightweight-formatted versions of the screen page. Yes, CSS is better but...

I see for a lot of these sites that only the screen version appears in a Google listing unless you dig deep and ask Google for all pages from that site. This seems to confirm the widely held belief that if you have duplicate pages, the duplicate merely slides down the SERPS and does not attract any other sort of penalty.
