Will my ink or toner still work in my printer?
Printer makers push firmware updates that can block third-party and remanufactured cartridges that worked yesterday. InkLockout keeps one page per printer with the current status, the firmware that did it, whether you need an account, and workarounds that sources actually back up. Every claim has a date and a link.
People are fed up. One owner's rant about printer ink subscriptions on X got about 92,000 views and 250 replies in October 2026 (post), and "cartridge suddenly stopped working" threads come up again and again on r/printers.
All printers (4)
| Brand | Model | Third-party ink | Account required | Last checked |
|---|---|---|---|---|
| HP | LaserJet Pro 4001 | Blocked after firmware 2606/2607 | Only with HP+ | |
| HP | OfficeJet Pro 7720 | Blocked after firmware 2602 | No | |
| HP | OfficeJet Pro 8025 | Blocked after firmware 2606/2607 | No | |
| HP | OfficeJet Pro 9015e | Blocked after firmware 2606/2607 | Only with HP+ |
No printer matches. More models are added most nights.
Status key: Works = sources show third-party cartridges working on current firmware. Blocked = cartridges with non-HP (or non-maker) chips stop after the named firmware. Disputed = credible sources disagree. Unknown = not enough dated evidence.
