When you hit print screen it copies the screen to the clipboard.  Open a grahics program, like paint, and you can paste it in.

 

Now, if you are trying to print one page out of a word document, go to File/Print, and choose Current Page, and it will print the one page that you are working on.  This sort of thing works in most programs.  Don't use the Print button.  Go to File and Print to open the Print Dialogue, where you can choose what pages to print.
