Printing A4 vs Letter from Crystal Reports

Does anyone know of an easy way to set your Crystal Reports to print
on either A4 or Letter and shrink to fit without changing your Report.
I currently have my reports set to run on Letter size paper and I
want to run the same report in China or UK. However, when I run the
report on A4 paper it cuts off the right hand side.

Thanks,
