Print Button Plug In

I am trying to add a print button to my website. The main reason is because when I try to print my timely calendar in monthly view, it is all scrambled. I was hoping to find a way to print the entire page with the calendar the way it looks on the page. I tried a bunch of print button plug ins, but none of them actually show the calendar when I hit print; it just comes up with the text on the page that is above the calendar.

Thanks in advance for any help!
