Printing SSRS Reports Using Report Manager

Hello all,
When I print the reports ( or export to PDF) in Report Manager, my every alternate page is blank? If the report is just one page report, I get second page as blank when I print or export. The report prints in Landscape format( which should be fine given 8.5 inch height and 11 inch width).
I have played with the interactive Height and other height parameters but with no luck.
My current settings in the rdl file is:
<BottomMargin>0.5in</BottomMargin>
<RightMargin>0.5in</RightMargin>
<PageWidth>11in</PageWidth>
...
<Width>11in</Width>
<InteractiveHeight>1.5in</InteractiveHeight>
<Language>en-US</Language>
<TopMargin>0.5in</TopMargin>
<PageHeight>8.5in</PageHeight>

I would highly appreciate any suggestions.
Thanks
