Preview/Acrobat Printing 2 pages per sheet ?

[brsboarder]

So, I have a pdf that I am trying to print. However, I want to print with 2 pages onto 1 page, and then do it double sided. I can't figure out how to do this. My printer doesn't print double sided, so, what I normally do is say, print odd pages, then even, however, here, if I say print odd pages, it will put pages 1,3 on the page instead of 1,2, 5,6. Is there a way to get it to print the "odd pages of my set" if you know what I mean? any help would be great
