SnagIt is a screen capture program, though it does far more than just print and save a screen, that has just released it's Verson 9.0
I've used several earlier versions and use it many times a day - well worth its $49.95 cost ($19.95 to upgrade). The new version simplifies both capture and distribution, and has some easy ways to combine images and documents.
SnagIt 9.0
also has a free trial, so download it and play with it for a few weeks. There are 15 online videos that make learning it very simple. The results, however, are anything but simple.

Hi Sharon - Snag it is a cool tool. I have used it every so often to try to get my point across. Thanks for the update on the latest version.
Sharon - Thanks for the reminder I will give this a try.
Sharon - This is a great product. I think in many ways it works better than a tablet computer because you can more easily capture screen shots beyond what appears on the screen. Doing this with a tablet tends to be more of a challenge.
Bill - as it improves with each version, there is more and more we can do with this.
Jennifer - I use it every day.
Sam - very interesting observation. I still haven't bought a tablet, and will probably wait to see what develops over the next year or so.
