If you are running Vista, you can use the snipping tool to do a screen capture of a portion of the screen which can be saved as a jpg and printed.
If you're not running Vista, you can use a little program called snippy to do the same thing. Holding down the shift key allows you to select a rectangular area rather than a freeform area.

Both are useful for lots of other things as well like printing or saving some data from a forum post, for example.
