How to print a booklet?

edit

I wanted to print a four page letter to my mother and have it flip open like a book, no problem easy as pie right? Wrong. I had to try a bunch of stuff to get it to work right. File>Print>Properties. Then chose Letter/Landscape/Short Edge (Flip)/Printer Default. My printer prints on both sides of the paper so this cpmbination worked for me. If ypu printer doesnt print on both sides, you will probably have to feed the paper in again manually.

Oh, I also had to change the font from 12 to 16, otherwise the words were very small, too small for an 80 year old beautiful mother. Even at 16, they're pretty small, so you might wanna try 18.
