I know exactly what you want but there are a few things to consider:
When you print it has margins, a header and a nice looking footer.
Try you may try you might but you will not find a way to do this
reliably using X/HTML pages.
Are there work arounds? Sure there is!
-You can generate the page in a .pdf form (if you use php check out
-Flash offers a print function which does not show the header & footer
(if you use php check out "ming")
I am almost positive there are others. I am almost willing to bet that
all you will find is IE hacks and so on. If it's for an invoice or the
like some consider a PDF to be very crisp and professional.
But in short I would say no. Don't count on getting rid of it unless you just want turned off on your computer in which case you can find it in your browsers settings.
