HP has gone one step further than the warning that pops up when users of its printers use third-party cartridges.

HP recently rolled out a firmware update for its printers,The update caused all users of third-party cartridges to be unable to print properly.

HP officials say the ban on third-party cartridges is because"Third-party cartridges that use non-HP chips or circuits may pose a threat to hardware performance, print quality, and security”。

In addition, the service will be updated regularly, such as alerting some users that they are running low on ink, the official said.

The update caused a lot of complaints from users, with one saying,HP cartridges are often more than twice as expensive as third-party cartridges, and they feel cheated by the mandatory use of official cartridges.

It's worth noting that Dynamic Security, which restricts users from using cartridges other than the original one, has been available in some printers since 2016.

Officials say the Dynamic Security feature will be used to protect the quality of the customer experience, maintain the integrity of the printing system, and protect intellectual property.

In 2018, HP paid millions of dollars in class-action lawsuits over the feature.

But apparently,That didn't stop HP from forcing the pricier official cartridges on users by limiting their choices and making the machine unusable.
