Sequoia 15.1 "Legacy Extensions" incompatible (hp and Canon)

[Batt4Christ]

My MBP just updated to MacOS 15.1 Beta (24B5046f) - and upon first start-up after the update, I was met with windows that mentioned Legacy extensions that would be incompatible with future updates to MacOS. Both mentioned extensions were printer-related (Canon and HP). Anyone know what's up with this?

I don't know about 15.1, but I successfully installed on Sequoia 15.0 Canon's extension CIJUSBLoad version 24.20.10 /Library/Extensions/CIJUSBLoad.kext
