I just installed Karmic AMD64. Initially my Samsung ML-2240 printer was detected and installed. After updating Karmic, I wasn't unable to start the printer. Although it was detected using lsusb, the printer configuration didn' t find any USB printer.
After reading, and trying, and more reading and trying, finally using your suggestion # 5, I succeeded in installing it.
Samsung ML-2240 is not included in the drivers list, so I installed it as an ML-2250 and configured it like Samsung ML-2250 Foomatic/gd
