I have the Samsung SCX 4500w and its IMPOSSIBLE on wireless network. Once I have paired it, which I´ve done four times now, after some time, for some reason - it disconnects itself from the net. So I cant access the IP adress, even though the configuration-report says that its still connected and has the same IP. So it wont print, unless I turn it off, and pair it with my router again. Samsungs customer service refuse to help me. They dont have a clue on how to resolve the problem when it comes to Macs. They dont even know OSX, they dont know the interface. They are just guessing what I have to do, and its shocking and awkward. Samsung really sucks with customer service for Mac! Does anyone have this printer? This is driving me completely insane, and I dont know what to do. Im considering returning it, and never buying a Samsung printer again. This is too bad, because the function is great, quality and design is great too. The few times it works, its great.
