Haha! I was at a friends office today where he uses a very simple Dymo Labelwriter printer. It was stuck with print jobs in the cue, and generally wasn't working. I uninstalled the driver, reinstalled the driver. Tried default Windows, and Dymo new drivers. The printer was recognized, USB, power everything was working. Finally, I gave up and said I think you need a new printer... He connected it to another computer and it worked! I had failed trouble shooting 101, reboot. I had failed to restart the printer.
Thanks for following up and sharing your solution... And Welcome to Geeks to Go!
