Query: Installation Nightmare!!!

I dont know about the installation on this thing. Tryed to install this with the Bluetooth card supplied and my new HP Pavilion with Bluetooth built in you would think it would be easy. No way!!. After two hours on my own, then two hours to a guy in India who did not know anything, I gave up. Boxed it up and sent it back. Its also bigger then you would expect, its not something you can put in a brief case with a laptop. Its way too big. Your better off bring a cheap LexMark printer with a USB cable.
