Till,
Good news! I installed all your packages from https://launchpad.net/~till-kamppeter/+archive/ppa
After that, I changed the printer ipp URL from http//zonhub.home:631/printers/ML1660Series (yes, this was the correct IPP URL before the upgrade to 12.03) to ipp14://zonhub.home:631/printers/ML1660Series and it now works.
Thank you
