Jeremy, while your investigation is interesting (thanks!), Google Maps printing issues are unrelated here. This bug is about wrong printing of some transparent PNGs in general.
This bug is closed as WORKSFORME since 2007-10-02 in 1.9 (Fx3), as long as attachment 112972 prints correctly.
Google's old workaround, resulting from this bug, is probably bug 282434 or part of it. If that's the case, comment in that bug. People CCd there might be interested.
