Print a screenshot (with the user's printer)

Hello everybody!

If I want to create a button which makes a screenshot and prints it what can I do?
I found some js code that creates a screenshot (unfortunately it works only in standalone and not in webplayer arrrgh!) but… to send it to the user’s printer? Is it possible?

I found some similar questions but I didn’t understand what is the correct solution.
Thanks!
