One of my sales reps has a Samsung 1710 at home and at work. She did have a desktop at home and at work and both printers worked fine. She just switched to a laptop that she carries home with her. She got the printer hooked up at work without any troubles, then she got home and plugged it into the same model printer there and it wouldn't work. I suggested that she re-install the drivers but it still only showed one printer, and still wouldn't work. I have never run into a situation like this and I am at a loss.
