How to take a screenshot in diablo 1 ?

[GPR]

Print Screen should work. You'll then have to open up Paint or something like that and then paste from the clipboard to see it.

I think that I give too little information.
Print screen was done screen, but shoot my desktop, not a game.
From Diablo instalation 1.09, Win 7.
I think that meybe I must installed some soft for making videos from gaming. :-(
