HP Outrages Printer Users With Firmware Update Suddenly Bricking Third-Party Ink (arstechnica.com) 199
HP is set on continuing to use DRM to discourage its printer customers from spending ink and toner money outside of the HP family. "HP have updated their printers to outright ban 'non-HP' ink! They no longer shows the 'can't guarantee quality' message, but instead cancels your print completely until you inset a HP ink cartridge," Reddit user grhhull posted Tuesday. "After contacting HP, they advised 'this is due to the recent 'update' of all printers.'" It's unclear when HP issued updates for which model printers, but there are alleged customer complaints online stemming from late last year, showing plenty of customers surprised their printer no longer worked with non-HP ink cartridges after an update. Some pointed to third-party brands they had relied on for years.
HP community support threads include complaints about the OfficeJet 7740 and OfficeJet Pro 6970. HP lists both printers, as well as others, as able to circumnavigate dynamic security under specific conditions. However, HP's support page states this only applies to models manufactured before December 1, 2016. For more examples, there are comments on HP's support community suggesting that HP's OfficeJet 6978 and 6968 were recently affected. Both printers are discontinued, but HP's product pages make it clear that the fickle nature of dynamic security means that third-party ink could stop working at any time. And HP's dynamic security page also leaves the door open for the sudden bricking of functioning ink: "Firmware updates delivered periodically over the internet will maintain the effectiveness of the dynamic security measures," the page reads. "Updates can improve, enhance, or extend the printer's functionality and features, protect against security threats, and serve other purposes, but these updates can also block cartridges using a non-HP chip or modified or non-HP circuitry from working in the printer, including cartridges that work today."
