On the installation disk there is a folder called CCC - find it (sorry can't remember where it is). Inside are 4 files UninstallL1..4* - execute them in sequence (they remove all remaining traces of the HP software - since HP's uninstallers don't work).

*If you used the original CD supplied with the printer that is fine. If you have since upgraded make sure you use the uninstallL1...L4 from the actual version for drivers you have installed. If you use the wrong ones they don't work (brilliant bit of design).

The original CD was used for the install but I cannot find folder CCC nor any *uninstall* files on it :(
cant find any info about these files in the HP (german) site, will try one of their english sites

I could simply reinstall the same version (22.0.334.0 - new version is 22.50.231) but would hope that the new version is better.
The HP site says to simply uninstall and install more recent driver on top (I know, dont trust...)
