System Crystal layout issue when changing paper size

Experts,

I need to change the standard Sales Order crystal layout to print on Letter paper.

If I leave this at A4 as default, then the user need to confirm this at the printer first before it prints. But when I change this paper Setup in Crystal to Letter, it prints a totally blank first page and the headers for the 1st page and 2nd page prints on the 2nd page.

Any help would be appreciated.

Regards,

Marli
