On October the 23rd a security certificate for HP printers expired,

almost everyone who has an HP printer was affected.

HP released updated drivers on the 25th October.

Click the + button at Driver Product Installation Software and download the HP Smart app, once

downloaded and installed run the app and this should download the new driver and get you printing again.


The HP Smart app should also be available in the App Store.
