Hi Sherry,
I think we should be able to resolve that. Here's what I would do.
- Disconnect the USB cable from the printer at the computer.
- Run the install.exe from HP UPD.
- Choose the USB Mode option and make sure both check marks under USB Mode are selected and click Next
- When prompted by the installer, connect the USB cable to the computer (make sure the printer is powered on) and click Finish.
Plug and Play should recognize the driver and a new printer should be created in the Devices and Printers folder.
