that seems to be exactly the bug, that I have noticed earlier and posted 
on this list under the Subject "Printer doesn't print formulas".

I have tried with several other printers and different fonts, but the 
result was always the same. It didn't occur to me, that evince could be 
the root.

I have tested the document (minus the biblatex parts) by printing it 
from evince and acroread and I can confirm: evince doesn't print it, 
acroread does.
What happens with other documents: evince prints until the first math 
formula and then stops.

A workaround is for me to pdf2ps and ps2pdf the document. After that, 
evince does print correctly.
