customize window.print() in drupal block

Question

I have used a block for adding an option to print the page.The content of the block is <a onclick='window.print();' style='cursor:pointer'>Print this page</a>

It works fine but I need to customize the content to be printed.How can this be done ?

Answer 1

You can customize what gets printed and how printed content looks like using media specific CSS:

<style type="text/css" media="print">
h1 { text-align: center }
</style>
