I'm guessing he meant that the numbers show up, but the lines don't. I've had this happen before, I had to uninstall and re-install pep designer to fix the problem.
if you read all the tabs its really helpful. I had the same issue. If you go to Settings, then to printer settings and make sure that both "print page number" and "Print alignment marks for multiple pages" are marked..... it should work
and if it is still not working for you, the way i got that to work was to go and hit print preview first, and then hit the print button on that page....
