In Keynote, if you want to print handouts, they don't let you print more than 6 slides per page. If you want to print more (9 seems to be the standard from Powerpoint), here's a trick that will let you do that. When you go to print you presentation, do not select the Handout radio button in the "Print" section, instead select the Individual Slides option. Once you do this, you then need to select Layout from the select option that is currently showing Keynote (see the screen shot below).



Once you do that, you can choose the "Pages per Sheet" and select up to 16 pages per sheet in your print out. You can also arrange the layout direction. Printing in this way gives you a lot more control of your presentation handouts in Keynote.
