My wireless HP Officejet 6500 will copy or print on anything once it's inside the printer, though I can't use very thin paper (like Kabnet wax) without it jamming. As far as not printing at all, the only problem I've been having with mine recently is not wanting to print some PDF files... it will feed the paper but then just spits it out blank on the other end. I've been wanting to get a new one because of that, and because my replacement ink cartridges are so much more expensive then some other brands, so will be watching this thread.
