Maybe by then openprinter would have migrated to their ink standard and started producing it. Old models’ ink cartridges can still be refilled but not changed.

From my understanding, they might still be able to develop a fully open source printhead that is compatible with the printer and sell it separately, but developing a copy of the said printer will be a breach of the patent.

HP 302 et HP 302 XL (Europe)

HP 803 et HP 803 XL (Asie)

And the ink they use is cheap/available internationally. I also think that one can refill these with regular ink bottles from amazon/aliexpress

In Marxism communism personal ownership is still allowed (you own your house and belongings etc.). What’s not is the control of the means of production or any property that lets its owner live off others’ labor, say factories, land, mines etc. by capitalists and argues that they should be the social or common property of the producers/workers.
