css media="print" css not working - Div tag not using my print css?

[Marc]

I want to print a DIV tag with css. I have a stylesheet media="print". This style sheet contains the DIV tag info that I want to print:

.testDiv {
border: 1px solid #0F0;
margin-right: 300px;
text-decoration: underline;
font-weight: bold;
}

When I use this div tag in my html. It does not read the css!
Anything I am doing wrong?

Cheers
