Is anyone else having problems with new "Driver" installations? There is no way to talk to a a person at HP. The Mac can't find the printer and I downloaded the new firmware and drivers but it won't complete the install because some HP software is missing.
iMac 21.5″, macOS 10.13
Remove the printer from >System Preferences>Printer/Scanners and add it back in to refresh drivers and certificates.
if you still have issue—
Open >System Preferences>Software Update (Command R will reload and do a fresh check)
Update: HP Printer Software 5.1 should now be becoming available through Software Update to fix this issue.
