Ok, the problem with Acroread I solved in a similar way. I opened /etc/cups/printers.conf and I modified the line with 'Option copies ' to put 'Option copies 1'. And then stop and start the cups daemon:
- sudo service cups stop
- sudo service cups start
Still I don't know how to get Okular doing duplex printing by default though...
