The don't look like the regular tickets from the booth. If you print at home, it will be a regular sheet of paper with a bar coded ticket printed on it. If you have them mailed to you, they look like paper Ticketmaster tickets.
As far as I've heard, there have been a few people whose self-printed bar codes haven't scanned at the gate. This might have been an issue with the quality of their printer or maybe there's an occasional glitch with Ticketmaster's integration with Universal's gate system. Not sure. In any case, the ticket were always honored. I've only heard of a small handful of these problems.
