Speaking to a human is itself an issue, but I finally made contact. Since doing a system update on my Mac, the printer will no longer respond. I've spent over 3 hours with Apple in two sessions and a further 45minutes this morning with HP Tech support. I'm told that my printer is now 5 years old and there is no further support with Firmware Updates for my Colour Laser Jet printer. These are expensive machines to replace every 5 years and I won't be buying another HP if this is the tactic to sell new machines.
