Hello... Need Help

[PeggyD]

Hello to you all , Im new to digital scrapbooking and I need some help. I'm getting married in May and want to make my own invitations with Scrapbook Max. I want to make them poast card size (save the date card). About the size of 4x5 . I made a test one and when I printed it out it came out with some of the boarder cut off. What am I doing wrong , Can someone help me with this ? Pleaseeee!
Thanks
