** Changed in: cupsys (Ubuntu)
For me the error_log looks like a problem of the CUPS backend and/or the
communication with the printer and not like a driver problem.
Please edit /etc/cups/cupsd.conf setting LogLevel to debug, restart
CUPS (sudo /etc/init.d/cupsys restart), try to print again and then
post your error_log again.
