PaperSize problem in Crystal Reports

I am using Crystal Reports 4.6 with VB6

I create a report of fanfold paper size on a PC in which the printer supports this paper size. When I use that crystal report file at other PC (the other PC's installed printer not supports fanfold paper size), the report view is in envelop size paper generally. This don't display complete data.

How can I get rid of this problem ?

Thanks
