Various browsers have various issues printing HTML/CSS and MathML correctly (mainly fonts are an issue?)
Since we've updated to MathJax 2.0, SVG output is now available and is supposedly much more reliable in printing. Need to test and see if this helps.
Would it be possible to have the setting for the the output mode separate for the printable version page (&printable=yes) which would be set to SVG per-default?
There is also https://github.com/mathjax/MathJax/issues/386, fixed in v2.2 and https://bugzilla.mozilla.org/show_bug.cgi?id=468568 in Firefox 18.
