I created the following thread in the Community Corner forum…
http://apps.magicjudges.org/forum/topic/1766/…and sometimes it is just a question of which browser are you using? The Judge Center seems to be most compatible with IE still, and less so with Chrome or Firefox. So, check that first. Other times, you can adjust the page breaks in the print settings for the browser, and making sure the margins and/or zoom are set accordingly.
The more time consuming work around is to copy and past into a program like Word, and then print from there. But, getting the document correctly formatted can be more trouble than its worth. Far better if you have a single generic exam you are using, rather than personalized exams.
But start with your browser first and work from there.
