I was able to connect to a shared Samsung 2160 with my Windows 7 laptop 2 weeks ago at work. I haven't been able to connect to this printer since last week. When I try to print, nothing happens. I try to connect to another shared Samsung 2160. It looks like its going to connect. And then it says that the path is wrong. I tried to connect to PC by entering the PC name in the Run box. Says the path is wrong. I am still able to connect to these printers via desktop. My laptop & desktop where the printer is plugged both have Workgroup as the workgroup name. I have Norton Security. It found 50 viruses last week which I cleaned. And I am connected to the internet when I try to connect to these shared printers.
