Yep. Evolution. I have this exact same problem with font size when printing. It was INSANELY large on printed paper. I have to tape the paper on the wall and read it from a comfort distance (literally).
There are quite few threads on this issue at ubuntuforums. Thus, it has been NOT resolved for a long time. Past due. -- Can't change font size for printing messages in evolution, and default size is too large https://launchpad.net/bugs/26023 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
