I recently purchased this printer.
HP's Dynamic security has decided to brick a full set of new ink cartridges.
How do I turn this feature off? I have found info online about it for other printers, but I can't find out how to do it for this one:
HP Color LaserJet Pro MFP M479fdw
At no point when we bought the printer did the listing say "only compatible with HP cartridges" so how can they get away with selling products like this? I feel that I have been mis-sold this printer if I cannot choose which brand of cartridge I use...

Welcome to the HP Community --
I am sorry you feel you were misled.
This printer series is indeed protected with Dynamic Security that limits the type of ink / toner that can be used in the printer.
There is no legal workaround or method to change the requirement.
The Community does not make policy, we do not influence marketing by HP or other merchants, and we cannot make changes to requirements. We are a user group.
We can -- and I will -- forward your concerns to our Moderator team.
Should the be a response, look for a message here before the agent uses other means to contact you.
The following is to help those who are interested in this series and is not intended to punish those unaware of the requirement:
For those reading -- please be aware:
A quick check of the HP Store USA shows printer has been discontinued.
The listing is still available at the HP Store
HP Store - USA - HP Color LaserJet Pro MFP M479fdw

Winning in business means working smarter. The HP Color LaserJet Pro MFP M479 is designed to let you focus your time where it’s most effective-growing your business and staying ahead of the competition.
HP Office Laser Multifunction Printers are designed for SMBs and small workteams in larger companies, delivering enhanced productivity, simplified workflows and reduced costs.
This printer is intended to work only with cartridges that have a new or reused HP chip, and it uses dynamic security measures to block cartridges using a non-HP chip. Periodic firmware updates will maintain the effectiveness of these measures and block cartridges that previously worked. A reused HP chip enables the use of reused, remanufactured, and refilled cartridges. More at:
