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?
