Kristian Erik Hermansen, then we will have to do some deeper investigation of your case.
First, can you do
cupsctl LogLevel=debug cancel -a
and then print a duplex job. After it completes, copy the CUPS error_log:
sudo cp /var/log/cups/error_log ~ sudo chmod 777 ~/error_log
and attach the error_log to this bug report.
As another test copy your print queue to another one which prints into a file:
cupsctl FileDevice=yes lpadmin -p test -E -v /tmp/printout -P /etc/cups/ppd/<yourprinter>.ppd
Print the same duplex job into this queue.
Then wait until "lpstat -o" does not show any output any more and copy the resulting file
sudo chmod 777 /tmp/printout cp /tmp/printout ~/printout.ps
and attach printout.ps to this bug report.
As an additional test send printout.ps to your real printer without filtering ("lpr -o raw ..."). Does it come out double-sided?
