I am using Conkeror 1.0pre1 and XULRunner 32.0 under Windows 10.0 Pro.

It behaves properly on bringing up Google Maps (maps.google.com),
except that when I try to print out a map (using the print facility),
the resulting window does not coincide with what I have previously
delimited (either in scale or in boundaries), and what goes to the
printer is something else again.

I can reproduce this on gecko 43. These kind of issues are very common with Conkeror and I'm not sure we
want an issue for every website that doesn't print correctly.
