And at the end of February 2023, there was another comment from Michael Hall on the same post with the following content: It seems that an HP printer stopped working with third-party cartridges after a firmware update. Let's show HP that we have power by not purchasing anymore of their products. This type of control should be disciplined. A business practice that is as mean and sneaky as what HP has done does not deserve another dime of my $. Going out today to buy a different printer. In mid-February 2023, a user posted this comment to my blog post Class action lawsuit against HP over blocked cartridges: New cases here on the blogĭue to the articles about problems with third-party ink cartridges here on, my blogs act as a honeypot, so to speak. Or a firmware update is sold as a security update, but blocks third-party ink cartridges along the way. Many users fall into this trap because the printers are connected to the Internet and the firmware updates automatically. I had regularly reported here in the blog about how the manufacturer Hewlett Packard modifies its inkjet printers via firmware in such a way that third-party ink cartridges can no longer be used (see article links at the end of the article).
