RE: The Samsung printer:
Are you trying to hook it up directly or as a network printer? If you want to use it as a network printer try using cups at 127.0.0.1:631 in your browser and step through the process. Use the ipp, (internet printing protocol), which should look something like ipp://xxx.xxx.xxx.xxx/ipp
. You might have to try one of the other forms that are listed when you get to that part, but your printer is listed in the printer list so there is no reason why it shouldn't work.
