CSS Printing Extensions

I read a CSS draft  titled "CSS Printing Extensions" where it talked about
page break when printing a document.  What versions of Netscape and Explorer
support the extensions?  I was trying to use the extension and could not get
the printer to page break using the following code from the above document:
<STYLE>
BR.page { page-break-before: always }
</STYLE>
....
<BR class=page>

Is it because the browser does not support it the reason why the printer is
not page breaking?
