Firefox:Printing what you see

It happens a lot of times that if you print a bad programmed webpage, that the layout is destroyed. This problem can either be fixed by the web master of the page in question, or firefox could try to fix it. Meaby if firefox takes some kind of printscreen of the webpage and then would print that. THEN, you would be able to print what you see (like a lot of people want).
