Nuts. Well so much for that idea

Do other comms functions work? Some examples:
- HP Utility is in the Windows system tray and gives any alerts from the printer.
- HP Utility shows printer status, ink status, loaded paper, etc.
- Printer driver shows which paper is loaded, etc (for example when printing from PS, etc).
- Able to calibrate and profile papers in HP Colour Centre.
- Putting printer's IP address in web browser opens the embedded web server interface (using ethernet connection right?).
You're using HP Utility 1.17.0.3 right?
