I have an iMac that just tried to load the latest version of the operating system, which is Sequoia

15.1. They ran into a problem with my HP printer. This is the message they sent me:

Legacy System Extension - Existing Software on your system loaded a system extension signed by

"HP Inc." which, 

will be incompatible with a future version of MacOS. Contact the developer for

support.

Any help please.

Updating to 15.3 may fix the problem as reported here
