HP Printer Firmware Lawsuit 2026: What Owners Need to Know About Third-Party Ink Blocking
Last Updated:
Several 2026 lawsuits accuse HP of using firmware updates to block ink cartridges that aren't HP-branded from working, even when those cartridges function fine. Here's what's actually being alleged and what it means for you.
What's Being Alleged
Plaintiffs claim HP pushed firmware updates through routine downloads that quietly added authentication checks, causing third-party or refilled cartridges to stop working or show false error messages. This follows a pattern reported by Ars Technica, where HP's "Dynamic Security" firmware has faced repeated legal challenges for limiting which cartridges can work in HP printers.
How to Protect Yourself
- Check your printer's update settings and consider disabling automatic firmware updates if cartridge compatibility matters to you.
- Before buying compatible cartridges, check user reviews for your specific printer model to see if others report update-related issues.
- Keep records of receipts if a cartridge stops working right after an update, in case you want to join a class action or request a refund.
