ps-print-buffer-with-faces does not work, ediff buffers

[Uwe Brauer]

Hello


Unfortunately it seems no longer possible to search the mailing list,
for I am sure that issue has been discussed.

It is as follows, I run  ediff-regions-wordwise and I want to print
the resulting buffers via ps-print-buffer-with-faces, the buffers are
print, but the faces don't appear.

What might be the problem?

regards
