I know what you're talking about. When we were going through the process, I printed out some test versions and compared them to what NVC sends out -- and they look identical to me. But I was always too paranoid to actually send in a home-printed version. Still, a lot of people here have used the system, with no problems.
There used to be quite a few threads about the subject, but I'm not sure what the latest experiences are. Try doing a search for "James' shortcuts" and see what you find.
Good luck !
