A lot of hardware vendors discontinue driver support for products after three years. This kind of failure with an OS upgrade is common. Yosemite, for example, killed my Samsung laser printer. I liked Yosemite, so I eventually bought a new printer.
Wow, that um..sucks. Glad I don't usually do anything Samsung. My Brother laser print, bought in 2010 still works well. I find it hard to believe a big company like Samsung would just discontinue support so quickly.
