Hi, Sorry to bump this topic, but I've got quite the same problem. With a Samsung CPL-300. I've tried the DLL's (v5.1.2600.2180 and v4.10.0.1998), but both won't work. And I can't find any other versions on the internet or on other PC's that I've got. (Installing the printer on another PC isn't possible) anyone who wants/can help me please? Edit: I didn't use Nlite, but don't want to open a new topic, I got here through google...
