In the past, I've had my printer (Canon PIXMA640) setup to print booklet & duplex to print books. Using it this way, the printer adds it's own margins and reduces the amount of text I can fit on a page.

Maybe it's new to Word 2010 or I didn't see it before, but there's an option in Page Setup to use book fold. This gives me more control over the whole page and pretty much allows me to print edge-to-edge in booklet & duplex.

Here's my problem: The reverse side of the printout is upside down. In the Word print settings there is an option to Print on Both Sides but the only option is to flip pages on the long edge. Flip pages on the short edge is not available and this is setting I need to use.

I've printed may books in the past, so I know the printer will flip pages the right way. So, how do I setup Word 2010 to duplex correctly?
