PrintScreen Software?

You would think for something so simple, a software would be available. I know I can Use PrintScreen to place a Screen print into Paint and print it, but multipile steps are required. Under XP I used a utility taht all I had to do is make the Window I wanted to Print the Active Window, I would press print screen and that window would print....basically...one step vs. 3 steps. I have tried the Gadwin Free Print screen....it also requires a few steps and the printed document comes out many times too small. Has anyone found & used a "One-Step" Printscreen utilitySoftware that all you do is press the PrintScreen key to print the Active window and the printed copy comes out, shall we say, normal print size?
