1 - Creating a print.css file .

The first thing to do is to create a new css file that dictates how a page looks when printed and set the media property to print .

<link rel="stylesheet" type="text/css"  href="css/print.css" media="print" /> 

You can also use one stylesheet for all media by set the media property to all

<link rel="stylesheet" type="text/css"  href="css/print.css" media="all" /> 

or you can use one stylesheet for more than one media by separate the media types with comma

<link rel="stylesheet" type="text/css"  href="css/print.css" media="print,screen" /> 
 

Use the first method for the print type and the other two methods are just for more information about the media types .
