Bottom line
This is not internet folklore; it is in HP's own documentation. On Dynamic Security-enabled printers, HP says cartridges using a non-HP chip may not work, and periodic firmware updates can maintain those restrictions. Reused HP chips can permit remanufactured/refilled cartridges on some affected models, but the printer still controls compatibility through chip authentication. If supply choice matters to you, the easiest solution is not to buy into that fight.
What this verdict actually covers
Dynamic Security is model-specific. Do not read this page as 'every HP printer blocks every non-HP cartridge.' Read the exact product page or manual and look for the Dynamic Security disclosure before buying.
The useful facts
HP says Dynamic Security-enabled printers are intended for cartridges with a new or reused HP chip.
HP documentation says periodic firmware updates can block cartridges that previously worked.
HP manuals state a reused HP chip can enable reused, remanufactured and refilled cartridges.
The disclosure is model-specific, so check the exact printer before applying this verdict.
What we would do
If you only need a basic monochrome home printer, we would compare the Brother HL-L2460DW first because Brother explicitly states its firmware updates do not block third-party toner. If an HP model otherwise fits you, verify the exact cartridge rules before paying.
Good fit if…
- Buyers who are committed to Original HP supplies and do not care about third-party chip compatibility
Skip or rethink it if…
- You want broad third-party toner/ink choice
- You dislike firmware having a say in which replacement cartridge keeps working
The catches
- A cartridge being compatible today does not guarantee it will remain compatible after future firmware on an affected model.
- The word 'security' describes HP's rationale, but from the buyer's perspective the practical effect can still be reduced cartridge choice.
- Some HP programs and models have additional subscription/update rules; this page is narrowly about Dynamic Security.
