wp_header

WhenI take view source of my wordpress site home page, it shows the css include lines which are generated by wp_header, I want to edit one element in it.

this is how it is

<link rel='stylesheet' id='wp-paginate-css' href='http://newsroom.moccu.com/wp-content/plugins/wp-paginate/wp-paginate.css?ver=1.2.2' type='text/css' media='screen' />

[Please post code snippets between backticks or use the code button.]

I want to change the media=’screen’ to media=’all’
Does anyone know how to do this ?
