The complaint centered on a firmware update issued in November 2020; it sought a court ruling that HPs actions broke the law, an injunction against the firmware updates, and monetary and punitive damages.HPs firmware updates act as malwareadding, deleting or altering code, diminishing the capabilities of HP printers, and rendering the competitors supply cartridges incompatible with HP printers, the 2020 complaint reads.HP calls using updates to prevent printers from using third-party ink and toner Dynamic Security. The term aims to brand the device bricking as a security measure. In recent years, HP has continued pushing this claim, despite security experts that Ars has spoken with agreeing that theres virtually zero reason for printer users to worry about getting hacked through ink.After years of litigation, in August 2024, HP and the plaintiffs reached a settlement agreement that Judge Susan Van Keulen approved on Tuesday [PDF].Under the settlement agreement, HP doesnt admit to any wrongdoing. It also wont pay any monetary relief to customers impacted by the November 2020 firmware update.However, HP agreed to pay $5,000 each to Mobile Emergency Housing Corp., Performance Automotive & Tire Center, and David Justin Lynch, who was eventually added to the complaint, to compensate them for the services they performed on behalf of the classes, HP said. It will also pay $725,000 in attorneys fees and expenses.A win for HP users comes from the company's legal commitment to allow users of specific printers to decline firmware updates that would push Dynamic Security. The now-approved settlement terms state: HP has agreed to continue making certain disclosures to users of Class Printers about Dynamic Security and data collection, and to continue to allow users of Class Printers to either agree to install or decline to install firmware updates that include Dynamic Security features. The disclosures that HP has agreed to continue making include the disclosure that HP collects printer cartridge data from Class Printers through the HP Smart App, and that HPs Dynamic Security measures are designed to block cartridges using a non-HP chip, and may be delivered to printers through periodic firmware updates.That requirement, however, only applies to specific HP printer models (referred to as Class Printers), which are listed below:HP Color LaserJet Pro M254DWHP Color LaserJet Pro MFP M180NWHP Color LaserJet Pro MFP M281FDWHP Color LaserJet Pro MFP M281CDWHP Color LaserJet Pro MFP M182NWHP Color LaserJet Pro MFP M183FWHP Color LaserJet Pro MFP M283CDWHP Color LaserJet Pro MFP M283FDWHP Color LaserJet Pro M255DWHP Color LaserJet Pro MFP M479DWHP Color LaserJet Pro MFP M479FNWHP Color LaserJet Pro MFP M479FDNHP Color LaserJet Pro MFP M479FDWHP LaserJet Pro M404NHP LaserJet Pro M404DNHP LaserJet Pro M404DWHP Color LaserJet Pro M454DNHP Color LaserJet Pro M454DWHP LaserJet Pro MFP M428DWHP LaserJet Pro MFP M428FDNHP LaserJet Pro MFP M428FDWThose printers were all impacted by the November 2020 firmware update that sparked the lawsuit. However, there are numerous HP printers subject to Dynamic Security that are absent from that list. After being criticized and sued multiple times for abruptly issuing Dynamic Security restrictions to already-purchased printers in 2016, HP has informed users that only specific printer models made before December 1, 2016, can remove Dynamic Security.HP also now provides disclaimers on the product pages for most of the printers that it sells, stating that the device is intended to work only with cartridges that have a new or reused HP chip and uses Dynamic Security to block cartridges using a non-HP chip.Periodic firmware updates will maintain the effectiveness of these measures and block cartridges that previously worked. A reused HP chip enables the use of reused, remanufactured, and refilled cartridges, the disclaimer says, adding a link to a support page about Dynamic Security. The support page notes that most HP printers can be configured to receive updates either automatically or with a notification that allows you to choose whether to update or not." However, some HP programs, like Instant Ink, require users to enable automatic firmware updates on HP printers.All this means that, despite the recently approved settlement, Dynamic Security remains a critical part of most HP printers, and HP will continue to feel entitled to use firmware updates to suddenly block printers made after December 1, 2016, from using non-HP ink and toner. Owners of HP printers made after that date that allow automatic updates and still work with third-party accessories shouldnt be surprised if that abilitys suddenly bricked one day.Dynamic litigationWhile HP isn't paying a sum to class-action members this time, it has previously agreed to pay millions in relation to bricking printers: In 2022, it agreed to pay $1.35 million to European customers, and in 2020, the Italian Antitrust Authority fined HP for 10 million euros. In 2019, HP said it would pay $1.5 million to settle a similar class-action case in California, and it paid approximately AUD$50 each to Australian customers impacted by Dynamic Security in 2018.Theres also an open case against HP regarding its ink practices, a class-action complaint filed in the US District Court for the Northern District of Illinois in January 2024. The lawsuit centers on Dynamic Security firmware updates pushed in late 2022 and early 2023" and accuses HP of creating a monopoly in the aftermarket for replacement cartridges [PDF]. The plaintiffs seek an order declaring that HP broke the law, an injunction against Dynamic Security, and monetary and punitive damages.Another lawsuit, filed in mid-2022 about some HP all-in-one printers failing to scan or fax without ink, was dismissed.HPs printer arm has other pressing matters to address, though. Earlier this month, a firmware update broke specific HP printer models, preventing them from printing, even when using HP-brand ink. HP told Ars last week that its actively working on a solution.Scharon HardingSenior Technology ReporterScharon HardingSenior Technology Reporter Scharon is a Senior Technology Reporter at Ars Technica writing news, reviews, and analysis on consumer gadgets and services.
