I haven't printed directly onto the Blanxx; I print to a clear mailing label and stick that to the card instead. I made some templates too, and use those to get everything lined up right. (The black horizontal line is part of the printing/template, so that's what gets lined up to the card itself.)
Of course, those files are on my Mac, and that hasn't been powered up for some time. Hm, might be good to fire it up again....
