The question: did you update printer drivers or OS?

It is almost impossible that it would stop working without updating
anything at all, neither TeX engines nor fonts nor printer drivers.

You didn't specify what operating system you are using. One very
ingenious example was Apple's update to OS X 10.6.8 when all
Type1-flavoured OpenType fonts failed to print on all Macs and the
whole system was broken. At that time printing from Cups helped.

This only tells you that both OpenType fonts are broken. Do you get
the same problem with TeX Gyre Pagella Math
(http://www.ctan.org/tex-archive/fonts/tex-gyre-math/opentype) or
Cambria Math (if you have access to that one)?

But then the old Type1 font is used.

I would say that either OS is "broken" or there is some very very
subtle problem that isn't manifested on anyone else's machine. From
what I understood you had the same problem with LuaTeX and you didn't
yet report if other OpenType math fonts cause problems.
