Like Dr Cheeseman above, I tried to connect a HP Laserjet 6mp to a works laptop that only has USB port. Similarly NO instructions were provided however upon plugging the cable in it detected the correct printer right-away (I thought that was it, unfortunately not!)...however it then only prints a line of rubbish/garbage instead of what you wish to print. Despite getting HPs online wizard, updating drivers, increasing print memory...essentially everything possible...it still doesn't work. Can't find any help on the net for sorting out this unintelligible font issue....don't buy these products!! It just wastes your life...leave well alone.
