I have the error message "Expired Certificate - check the printer for errors". Using a HP Smart Tank 7000 series - I am trying to print from a MacBook with IOS 15.3. Everything worked fine until today.
I have:
- powered printer on/off
- reset the router
- uninstalled and re-installed the HP Smart APP
- removed and re-added the printer
- Updated MAC iOS
- Created a new certificate
- used the IP address - when I press print - pages come out of the printer (and don't stop) but with no ink - the ink levels are shown as empty - which they are not.
All of the above done multiple times- Any help would be much appreciated.
Thanks
