Turn on a switch with a computer

Is there a hardware that could be turn on with a computer so that it gives power to my printer for example via my computer. A great example of a hardware that does this is my external hard drive. It turns on when I go to start, my computer and click on it. I will like to be able to conect anything to that hardware so that if I conect my lights to that switch then I could turn on and of the lights with my computer.
