[XeTeX] Printer doesn't print formulas

[Tobias Schoel]

Hi,

since some days ago, my printer stopped printing documents with math 
formulas correctly. He prints until the first formula, then stops and 
ejects the paper.

The documents are all created with xelatex using TeX Gyre Pagella, Linux 
Biolinum O and Asana Math.

I haven't updated anything lately except for siunitx, which isn't 
involved in all of that documents.

This may sound like a printer bug, but lets look at the following 
minimal example.

\documentclass{minimal}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmathfont{Asana Math}
\begin{document}
\[\int_1^2f(x)dx\]
\end{document}

The printed document will be empty.
Replacing Asana Math by XITS Math results in \int_1^2 being printed, the 
rest not.
Removing fontspec, unicode-math and \setmathfont alltogether results in 
the whole formula being printed (in default font of course).

It could be a printer bug as well as an OS bug: The documents are 
printed finely on another printer feeded by Windoof.

Where might the root of this evil lie?

bye

Toscho
