How do you do this? Through iWork or Preview! It seems like it's the only advantage a Windows OS has over it as I've never seen a program on Mac that will let you take a lot of slide and condense them into four on a single page for easier printing. Why is this not possible? Is there any free-ware program I can download that will let me print out a 90 page powerpoint presentation/pdf/whatever in this manner? MUCH THANKS.
