Use the print screen key on your keyboard. Might need shift, and works a little bit different if you press alt at the same time (should be window in stead of screen).
Then the screenprint is on the clipboard.
Paste it into any application you like (Paint, Irfanview, Word, Photoshop) to manipulate and print it.
There are some nice programs offering some more functionality than this basic one. Try http://www.webtree.ca/newlife/printkey_info.htm
Hope this helps.
