Apple releases the OS and HP isn't ready. The same situation has happened several OS' before. HP has again found itself behind the curve ball. Running the program sees the Enterprise LaserJet M751dn and even the DesignJet T730 but the Easy Start doesn't find the correct drivers and ends up directing me to HP for support. HP does has a new Easy Start dated 26 OCT, 2021 indicating it works with macOS 12 but it does not. This is not he case as HP and Apple have both said that drivers come from HP, as the recommendation is on your website. They continued to say that HP was waiting on Apple to provide the drivers for macOS 12 Monterrey.
