Does anyone know of any attacks, either PoC or in the wild, that use malicious printer cartridges to infect printers? I saw this article from 2022

https://www.action-intell.com/2022/10/05/hp-bug-bounty-program-finds-reprogrammable-chips-open-printers-to-malware/

It says that HP's Bug Bounty program found such attacks are possible, but there are no details about who reported the bug that made such attacks possible. I remain skeptical about the accuracy.

Any help from experts in the form of pointers to attacks or analysis about whether printer cartridges are a viable infection vector would be much appreciated.
