hide links from the print (they cut my articles)

Hi,
I need a help. When I print an article from my site http://www.homosum.it appear a link that cut vertically the body of my articles (I don’t know how send you a preview to show this).
I don’t understand what code I have to use to hide this link. Please, can you help me? It’s not only a question of aesthetic, because this link cover some words of the article making difficult to read it.
Thanks in advance 🙂
