[STR New]

Using Linux Mint Debian Edition:  After the last system update,  upgrading
CUPS from 1.5.0 to 1.5.2 via Synaptic,  my network printer Kyocera
FS-C5300DN does not print anymore:  

After printing to it,  its "Data" indicator flashes and the printer stalls
for about two hours (!),  then printing one more or less complete page and
an error message like --

ERROR:
undefined
OFFENDING COMMAND:
6830.30.7
STACK:
3196.21
-mark-

or for instance 

ERROR:

OFFENDING COMMAND:

STACK:

I have already deleted the printer and reinstalled it without success, 
using Kyocera's 
ppd from
http://www.kyoceradocumentsolutions.de/dlc/de/driver/all/linuxcups1_4_zip.-downloadcenteritem-Single-File.downloadcenteritem.tmp/LinuxCUPS1.4.zip
.  

The previous CUPS 1.5.0 worked fine with this ppd.  
Another linux machine with the same LMDE and CUPS 1.5.2 and ppd has the
same problem.  
Windows machines still print fine (after that two hour's wait).  
Another printer (HP LJ2200 via a Fritz!Box network print server) still
prints fine.
