printing/forcing html page in landscape mode using css

Hello All,
I want to print one html page in landscape mode(both in IE and firefox MOzilla)

[CODE]<style type=”text/css” >
table {
border:1px solid #999999;height:234px;width:378px;
size:landscape;

}
html {
margin: 0px;

}

</style>[/CODE]

and use above mentioned code in my php page but nothing can be happen.
Also in some forum I found it may or may not possible to force html page or browser to print in Landscape mode.

Any help is appreciated.
