Screen Print Button?

I have an ignition system which always displays a footer window, a left hand side Menu window and a main mimic window, so at all times there are at least three windows opened and visible.
Our customer is looking for a print button on the left Menu window which will print the entire screen (ie. all three windows ), is it possible to do this?

Yes, you can!

Thanks for that!
