--- Comment #10 from Johannes Meixner 2010-07-06 08:04:24 UTC ---
Werner,
it seems the
"fix for bnc#592279: make cups device work with newer HPLIP"
is perhaps not really the latest correct working version
of the CUPS raster driver.
Reasoning:
In
http://bugs.ghostscript.com/show_bug.cgi?id=691029
an attempt to fix from Till Kamppeter introduced a regression,
see this comment in the Ghostscript bug:

This has introduced a regression.
When using '-r600x600' (as the turboprint driver does),
the raster output is garbled, .
Reported separately as
http://bugs.ghostscript.com/show_bug.cgi?id=691108
--------------------------------------------------------------------
This regression was fixed by Till Kamppeter, see the next comments:

Fixed in SVN rev 10890.
Till Kamppeter 2010-03-09 17:07:10 UTC
The remaining problem was that the bitmap memory did not get
reallocated when the color depth has changed. This also changes
the bitmap size. The fix adds two static variables to track
color depth changes.
---------------------------------------------------------------------
Please have a look if our
"fix for bnc#592279: make cups device work with newer HPLIP"
is really at least SVN rev 10890 (in particular that there
are the "two static variables to track color depth changes"
included).
