I highly recommend not depending on browsers for printing.

Instead, I recommend using some other tool to render a PDF out of your
backend: MapServer, for example, has a PDF output. Using PDF output
(instead of browser-based printing) means that your renderer is in
control of styling of the map, and you don't have the issues with
overlays or anything else.

http://mumbai.freemap.in/ uses this technique.

That's always been my recommendation, and I'm sticking to it :)
