HP Printer Ink Blocked by "Dynamic Security" Update
13 Mar
Summary
- HP firmware updates disable third-party ink and toner functionality.
- EPEAT 2.0 registry prohibits firmware that blocks remanufactured cartridges.
- Int'l ITC criticizes HP's "Dynamic Security" for environmental compliance.
The International Imaging Technology Council (Int'l ITC) is urging for accountability from HP regarding its "Dynamic Security" firmware updates, which reportedly render third-party ink and toner cartridges non-functional. This practice has been a long-standing feature of HP printers but is now facing renewed opposition. The Int'l ITC points out that such firmware updates are explicitly forbidden for devices registered under the General Electronics Council's (GEC) EPEAT 2.0 registry, which aims to promote sustainable products and responsible manufacturing.
The EPEAT 2.0 criteria, launched in December 2025, outlines specific requirements for imaging equipment to ensure they do not impede the use of remanufactured cartridges. Manufacturers must either avoid firmware updates that disable compatible aftermarket cartridges, provide an approved solution for uninterrupted remanufactured cartridge use, or offer remanufactured cartridges for sale. As of early 2026, while EPEAT 2.0 is new, the Int'l ITC is skeptical of HP's adherence, citing recent firmware releases for multiple HP printer models shortly after the EPEAT 2.0 registry's inception.
HP's "Dynamic Security" has previously drawn criticism from consumers and security experts. The Int'l ITC's executive director noted that HP is unique in its use of lockout chips triggered by firmware updates justified by security. In 2023, the Int'l ITC unsuccessfully petitioned the GEC to remove HP printers from the original EPEAT registry due to similar concerns, aiming to strengthen such clauses in EPEAT 2.0.
