Can't get to a print a page on a physical single paper

[sameer2]

I am trying to print some documents with Adobe Acrobat 9. When I issue a print, I get back-to-back pages printed on the same physical page to the top left. I don't see an option that changes this setting. I am attaching the screenshot of properties that can be changed, but none of these help me. There is a multiple page setting, making changes there doesn't make any changes to the printouts.
