Problem when print checked input[type=radio] on IE9

[Leidson-zz]

I had a problem to use this plugin for print a page with input[type=radio] on IE9, because the .clone() function used at function '_getElementHTMLIncludingFormElements' don't make a copy of the checked state in this case. It's a reported bug http://bugs.jquery.com/ticket/10550. I got around this problem modifyng the .clone() function for the .html() function and worked for me.
