I'm posting his as Xubuntu, bit I would assume this works on any variant. Yesterday (Thursday Jan 19 2012) I bought a Samsung ML-2955DW Wireless Laser Printer (Black & White).
The software CD includes drivers for "various Linux OSes" But after trying this setup a few times, I stopped. It is quite difficult to get the install GUI to work and when I got it to work, it caused the computer to reboot in the middle of the install. Useless.
Going back to the Ubuntu printer setup, that comes with Xubuntu, I just kept trying Samsung drivers that I thought might work. Well one did. The Samsung ML-3050, 2.0.0 driver works great. Hope this information helps someone out there
