Any way to force webpage to print exactly as it looks in browser?

Hey guys I'm looking for options on how to deal with an issue as I don't
think there is an easy fix.
We're dealing with a really stubborn client that doesn't want to accept
the fact that browsers don't print css backgrounds by default.
He's convinced that XP running IE 6 & 7 are the most common browsers and
we are a bad company for not supporting them. (I've shown him analytics
from our typical client's visitors but it hasn't changed his mind). I'm
rewriting his site to work on them but am stuck with the print stuff now.
He would like (demand is a more accurate term) to have the page print
exactly as it looks on the site as well as them look exactly the same in
all operating systems & browsers. I don't think it's feasible to go
through and put all the images in the html instead of in the css and I've
tried the list-style tip without luck. Lots of the color of the site comes
in from background css colors as well.
Is there any other options? Or even suggestions on how to deal with this
client?
