Create a Print Stylesheet

Question

Hi,
I was wondering if someone could give me some guidelines on how to create a print style sheet and how to include a C# button which will reference the styles once clicked.

I understand that I will need to create a new style sheet and define what I want to be visible and non visible on the page print out.

e.g #Menu1, #button
{display:none;}

However I am uncertain of how to link this style sheet to my web page and button click.

Thank you for your help.
