Yast2 recognizes the Samsung ML-2165W USB printer correctly, but it appears to
have no driver for it (even after installing Splix and all the other additional
driver packages). The same printer works out-of-the-box on Ubuntu, so I reckon
that suitable drivers *do* exist. (In fact, I believe Samsung is providing a
driver, even, though it may not be open source.) I think it's possible that
Splix has a driver for that printer, but the ancient 2.0.0 release used on Leap
appparently does not. Other distributions seem to prefer the latest SVN
revision 315 of the splix package since it has had many updates that were never
released properly (but which do work nicely in practice).
