HP does it differently now.
Recent HP ink cartridges no longer include the print head, so the main thing keeping them from reuse is the DRM "ink level" chip HP puts in them. If you use non-HP cartridges, but fail to turn off "auto-update printer firmware", your cartridges stand a good chance of failing to work after the next "security" update.
The security update generally includes "disable usage of known 3rd-party cartridge chips".
Yes, HP breaks your printer in a misguided attempt to sell you ink at higher than "Chanel Number 5" prices.
They call it "Dynamic Security", as if being unable to use 3rd-party ink was a feature.
