Not a class action but given the smallish $ per user I could see this being effectively pursued with the seller and if that doesn’t work through small claims court, at least in places like the UK/EU.
This is a change to the functionality of the printer post sale, and that tends to be viewed as an unreasonable action and one where one sided user agreements can be read by the courts as unfair to the consumer.

The important point is the the printer no longer works as advertised and as a starting point this is guaranteed in European law for six years after purchase. (https://europa.eu/youreurope/citizens/consumers/shopping/gua...).
