Windows 7 takes over the Print Screen key (labeled PRTSC or PRTSCN on some keyboards). Instead of sending the stuff on the screen to the printer, the Print Screen key sends it to Windows 7’s memory, where you can paste it into other windows.
You can take a picture of what is on your screen by pressing PRINT SCREEN (PRTSC or PRTSCN on some keyboards). This is called a screen capture. You can then paste the screen capture into a document, e‑mail message, or other file. There are two types of screen captures you can take: the entire screen, or just the active window. For example, if you have three programs open at the same time, you might want a screen capture of only the active window.
Some keyboards or mobile PCs that don't have the PRINT SCREEN button might use other keyboard combinations, such as FN+INSERT, to take a screen capture. Check the information that came with your computer or the manufacturer's website for more information.
To copy the entire screen
- Press PRINT SCREEN.
To copy only an active window
- Press ALT+PRINT SCREEN.
If you hold the Alt key while pressing the Print Screen key, Windows 7 sends a picture of the current window — not the entire screen — to the Clipboard for pasting.
If you really want a printout of the screen, press the Print Screen button to send a picture of the screen to its memory. (It won’t look like anything has happened.) Then click Start, choose All Programs, select Accessories, open Paint, and click the Paste icon from the top menu. When your image appears, choose Print from the main menu to send it to the printer.
Not really, you have to use paint to paste the picture. What ever application that supports pictures can be used. for example, you can also open a windows word and paste. or a excel, or an E-Mail application, what ever supported.
