Opera 12 prints whole page

[Rast1234]

Thank you for such a great plugin! I tested it's basic functionality (print given element) across Firefox, Chrome, IE11-10-9-8 and both "new" and "old" Operas. It works everywhere, but Opera 12. If I call .printThis() on a particular element, it prints whole page.
Jsfiddle: http://jsfiddle.net/dJjMz/2/

Why Opera 12? Because some people didn't like new engine and refuse to move to another browser. D'oh..

BTW, what does comments on that lines mean?

line 26: what (who) is S. Vance?
line 53: "IE works if document.domain is not explicitly set" - this place is executed if browser is not IE, maybe I don't understand something? :)

I removed support for Opera, as for Opera you have to create a entirely new page/tab instead of the iframe. It just gets too complicated.

this older plugin, on which mine is partially based, supports Opera:
