What is Print Screen?
Print screen is a keyboard function that takes a quick “snapshot” of your computer screen, copying it to the clipboard. By pressing the print screen key, then opening a paint or image program, the screenshot can be pasted into the program as an image file. From there, it can be saved or printed. If you don’t need a snapshot of the entire screen, but only want an image of the active window, hold down the alt key while pressing the print screen key. This is a great way to save menu screenshots for instructional Web pages, making it easier for people to follow along when configuring software, for example. You might also use the print screen key when ordering merchandise online. Upon completing the ordering process, a confirmation page is normally displayed. Rather than printing this page, you can elect to use the print screen key to save the image file until the merchandise arrives. This conserves both paper and toner. However, print screen only preserves what is readily visible on screen
