I just got one of these, cheap and cheerful printer, it installed perfectly with HPLIP, autodetected spot on.
Very nice, except the colour balance is wrong, the colours are too bright, orange comes out closer to yellow for example.
There are settings in HPLIP for:-
Brightness
Gamma
Saturation
Hue
But I have done repeated print tests changing these quite drastically, and to be blunt, they just don't do anything.
I installed this package

And that gives me perfect colour balance, but sacrificing significant quality, there are banding issues and obvious graininess that doesn't show up with the HPLIP drivers.
Quite happy to try any suggestions, alternative drivers etc.
