Don't always trust the packaging. I've bought specialty printer papers that were supposed to be able to go through printers but got completely stuck.
In one case it was a type of paper that would transfer an image onto ceramics and I managed to talk the tech guys at my university into letting me use the library printer. When the paper jammed it took nearly an hour to fix it and I wasn't exactly popular there after that. Which was extremely annoying, because it did say on the packet that the paper was safe for using in printers, and in fact was meant to be used in printers.
