Windows will now automatically try to reinstall the printer.

 If two HP PNP Scan Null drivers were displayed under Imaging Devices, no further action is required.

 If there are two old HP PNP Scan Null drivers installed, you will have to repeat the action in Device Manager.

 If only one HP PNP Scan Null driver was installed, you will have to reinstall HP UPD 5.5. Use pnputil-*.inf (drivers

which are already installed will not get changed).

Then disconnect and reconnect the USB cable to restart the Plug and Play installation process.
