I'm not surprised the HP jumped the gun on shipping the warranty card on CD instead of paper. They have to include a disc with the printer for the printer's drivers, so why not load a PDF copy of the warranty on the disc? If you're manufacturing millions of printers, that's a big cost savings in paper. I still don't excuse them for not making the warranty easy to find. Even if not required by law, good customer service means that they should make it easy to find the warranty, such as on the CD's label, and/or on the autorun menu, or in the disc's folder structure. It's not very hard to put a "warranty" folder on the disc and load the PDF file in there, is it? But I guess that's not the way big corporations work.

Lastly, am I the only one who's surprised that there's a law allowing manufacturers to supply the warranty on disc (or online) in lieu of a paper copy? I had no idea that such a law exists!
