VBA: Resuable quick print button for ppt

This is a program that will allow you to quickly print a three page per sheet handout in Microsoft powerpoint. The code should be saved first as a pptm file for future editting, and then as a ppam file, which can then be installed as an addon. Multiple buttons can be created using this code, much of which was written by Shyam Pillai in his PowerPoint Add-in FAQ.
