Some templates are clever and add the links after the link in a print view, the reason for this is you don't know where the link is on a text document, so we print it.
Unfortunately, this is really bad in a JEvents view like the monthly calendar. The url is at the bottom of the page so users can just find the exact page that way.
So we can use this code in your templates Custom CSS section. The code is:
[codep]@media print { #jevents_body a:after {content:"" !important;} }[/codep]
This should then revert your print layout back to normal.
