Printing maps in IE

I've been doing some amateur web development for a local funeral home,
and I decided to use google maps for our directions.

I've read all the posts on printing in firefox, and I'm content with
the lack of polylines on printout from FF, but I have a problem with IE
that I haven't seen addressed (after extensive searching). I'm using a
media:print CSS file to strip out the menus and page header, leaving
the parts I want to print. The problem is that IE seems to blow up the
print section by about 10-20%, which causes the border to fall off the
edge of the page. The information is intact, but it looks poor compared
to the firefox print. Does anyone know of a way to get IE to condense
to the right size, or why it enlarges it like it does?
