Recently, HP released a firmware update for some inkjet printers that disabled certain third-party cartridges. The claim is that the customer “is exposed to quality and potential security risks” when using counterfeit cartridges. I'm curious why HP is claiming that users shouldn't trust HP's abilities to secure their devices against attacks from malicious cartridges, but that's probably not an implication that HP considered when publishing this press release.
Also, if the intent was to inform users about counterfeit and potentially malicious cartridges, you would think that they would have provided an override method from the start. Thankfully, they are now. HP is preparing an optional firmware update that does not check cartridges. They claim that it will be available in a couple of weeks, and provide a link to where it will be hosted.
So yeah, they are doing the right thing now. Still… come on.
