Print Screen capture is an utility whereby you are able to take a 'snapshot' of your computers screen exactly as it looks the moment you take the capture.
To do it, you need a picture editing program. luckily, Windows comes with one called 'paint'
Get the screen in such a way that the part you want 'captured' (or 'printed') is as you want it, then press the [Prt Sc] key once.
Then open your Paint program (Start > All Programs > Accessories > Paint) Select File > Paste.
Edit the picture as required, then save it.
(the picture will usually be displayed in the 'select all' mode, enabeling you to 'drag' the whole picture so the top left corner of the bit you want to save is in the top left of the screen, cutting the bits you dont want out.)
Voila!
Have a play with a few random screen prints before you go for the master, that way your mistakes wont matter
