Printer display is normal. And I get the USB tone when unplugging/replugging the USB cable at the printer. In "Devices & Printers" it shows the printer. In "Device Manager" under Ports it also shows the printer. In both instances it says it's working properly. And.....it's working properly now! I just imported, sliced, and transmitted a part and the printer is heating up. The only thing I did differently is that I had given up on getting anything done today so I had shut the printer off about an hour ago. Previously I shut it off for about a minute or two. Weird! Thank you very much for taking the time to reply, maybe it was just your good aura that fixed it! ;-)
