What version of Windows are you using it on at present, or have you been in the
past? If XP then get the latest versions from:

There's a main download and an update.
If you have any
HP software
that you have tried uninstall it using Remove
Programs and then disconnect the USB cable from the
PC
end and install the XP
software as follows:
Locate the downloaded file ps804en.exe 1/1 (70.62M) on your computer, Right
Mouse Click on it and select Properties / Compatibility TAB.
On that TAB, check Use Compatibility mode and set it to XP with SP2 and also
check lower down the [x] Run as Administrator and OK your way out.
Do not connect the device until the installation procedure tells you to or
until you get to Finish.
Then repeat the procedure on the downloaded update file ps803mu.exe 1/1
(373.11k) although you can leave the USB cable connected unless it tells you
otherwise.
