Hi Alessandro,
I liked your idea about the Print button so I looked into it and found a different code that works and validated on my own page.
Where the "Notice" area of text is at the top of the page, add the following after the text has finished but before the closing "</span> tag:
<input type="button" onclick="window.print()" value='Print this page' />This creates a Print button that is not printed with the rest of the page and you can change what it says on the button by altering the text in the "value=" part.
