Hi @texkeller,
Welcome to the HP Support Community
I understand you are facing an issue with your HP Printer. Not to worry I will help you to get a resolution to resolve the issue.
We have to perform an NVRAM Reset to unlock the features of the printer.
The reset instructions are specific to your printer and performing those steps on a different printer may brick the device.
I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer.
In order to access your private messages, click the private message icon on the upper right corner of your HP Community profile, next to your profile Name or simply click on this link.
Hope this helps! Keep me posted.
Please click “Accepted Solution” if you feel my post solved your issue, it will help others find the solution. Click the “Kudos/Thumbs Up" on the bottom right to say “Thanks” for helping!

The Software and Drivers for HP Color LaserJet Pro MFP M281fdw page has a link to firmware update 20220414.
I downloaded the Mac package and installed the update with no issues.
The new cartridge is now recognized as a genuine HP product.
I have turned off the automatic firmware updates on the printer.
