The printer updated a couple of months ago blocking use of any cartridges that aren't from HP.
I looked through the list of rf files but my printer wasn't listed.
Can anyone help?
MacBook Air 13″, macOS 15.6
I've never heard of it being possible to downgrade those types of firmware updates in any of the news articles about that atrocious behavior by HP.
Sometimes firmware can be downgraded on some devices while other times it may not be possible. I know that even if some firmware can normally be downgraded on a particular device.....once in a while a vendor may release a firmware update that cannot be downgraded.

FYI, the next time you purchase a printer, I would recommend voting with your wallet & purchase another brand which doesn't cripple a printer after you purchase it. HP has proven they will cripple printers after purchase.
