What is the simplest/easiest way to display line of text only when printing a webpage using PHP?
<p>I have a line of text I would like to display only when a webpage is being printed.  Is it possible to only display this line when printing the page or doing a print preview using PHP in some way?</p>

<p>Basically, I want to print a page without the print headers, but would like to include the page's URL within the page's content when it is printed.</p>
