Crystal Report PaperSize setting

Hi all masters

I am using Crystal Reports for reporting with VB.net

At the time of report design time I set the paper size to A4.

Now using crystal report viewer's print button it prints the report assuming paper size what is set in default printer's preference options. (even if I set paper size property of print option of the Report Document at run time).

It prints correctly if I change the paper size in print dialog box of Crystal Report viewer.

[using Report Document's PrintToFile method works fine but parameters are not used which are set at run time]

Thanks in advance
