PrintKey allows printing anything on the screen to the printer. Once loaded, it sits in the task bar.

Doubleclick on it to capture the screen and right click on it to remove it from the Registry and computer.

Hit the Print Screen key on your keyboard and the program grabs the current screen, and is ready to manipulate (cut, crop, convert to gray scale, etc) then either print or save to file. Very intuitive, easy to use interface. Low resource consumption.
