By default, when a website is built using Bootstrap URL’s (href’s) are displayed when you print the page, right next to any linked content.
This comes from bootstrap.css, specifically:
@media print { ... a[href]:after { content: " (" attr(href) ")"; } ... }
To hide the URL’s from your printed webpages you will need to use your CSS styles to override it.
Simply add this to the bottom of your CSS file:
@media print { a[href]:after { content: none !important; } }
