If you've been annoyed that your HP printer doesn't work with non-HP ink and toner, a recent class-action lawsuit settlement means you can decline the update forcing the change, but only if you have a few specific models.
With a 'long-term objective to make printing a subscription', HP set in place 'dynamic security' systems that authenticate ink and toner cartridges in your printer. The 'dynamic security' system changed printer compatibility digitally to disallow some printers from working with non-HP ink and toner. This means that some users bought printers without those restrictions, only to find them added in via an update, after purchase.
