landscape orientation in html page

As per the requirement I supposed to show a report in html page with a print option. I want the report to be printed automatically by clicking the print button without having the user to change "page setup" - "orientation".

How do I control the page to be printed landscape, when print button is clicked.

Thanks in advance.

This question is asked once a week and there is no way to do it with the current browsers. Future versions should use a CSS property to determine it. Right now you only safe bet is to use a pdf for them to print out.
