Boca going crazy?

Our Group Sales Manager is having problems that I think are related to her new Boca printer versus Tessitura, but I'm not sure how to isolate the issue. What's happening is that when she prints orders (especially large ones) the same ticket prints multiple times (same ticket number and everything). She also has instances where only the bar code prints on the ticket and nothing else. I checked the things out in back end through SQL and the seats that are printing multiple times only show one ticket number and don't show as re-printed.

We're on v15.0.4, but she was also having this issue in 12.5.1 so it's not related to the upgrade.

Have you encountered this issue? What solution worked? Where else should I be looking for problems within Tessitura?

Thanks in advance for any help!
