If you want to keep a record of what is currently displayed on your screen, then you can print a screen shot of your display. You may have noticed that the "Print Screen" button on your keyboard doesn't seem to do anything. In fact, the "Print Screen" button prints the display to the clipboard, and from there you must take additional steps to print it. Originally the "Print Screen" key did print directly to the LPT1 socket (the old printer socket) but since its extinction, it prints to the clipboard instead.
