How to unistall hardware (printers) that seem to be incompatible?

It is a driver. Does the driver installer package also have option to uninstall?

fwiw, this is not notebook community, and might want to check out the Mac OS community area as well.

Does HP have support : how to install and latest driver and FAQ?

Might want to add just why too.

System preferences > Print & Fax ...

...The left side of the window shows a list of installed printers. Select the one you no longer want and use the Minus [-] Icon below the box to eliminate it from consideration. (The Plus [+] Icon can be used to add a different printer or try again.)
