Programming Netscape to Disable Print Headers and Footers

Greetings,

I'm in somewhat of a jam and was wondering if there was anyone out there 
that could give me a helping hand.

The issue at hand is a client is wanting the header and footer to remain 
hidden when printing, because the printed page is to be filed (they're 
invoices).  I've managed to do this successfully in Internet Explorer, 
but have had NO luck in reproducing this functionality in Netscape.

One other very important thing to note: the client would like to be able 
to achieve this without ANY interaction with the browser.  So going to 
'Page Setup' is not an option here.

I'd like to think that this is possible in Netscape, given that the 
competition has this functionality (via ActiveX).  Will the Netscape SDK 
offer any answers to this?

Thanks for your help.
