SAP Script not printing as viewed in preview

Hi Experts,

I have a SAP Script which is driven via RFFOUS_C Program.The script is using custom page format which is created via SPAD.

I have a wierd issue like i can see all my data in preview but when i print all the lines are not printing as viewed in preview.Its printing from top of the page till 70% and the bottom portions are not getting printed.

How can I solve this?

Thanks,

Siva
