@GustavinoBevilacqua @yogthos I was *wildly* curious about it too. I imagine a public key cryptographic mechanism, but I do not know how it actually works. My keenness to get my money back completely overrode my curiosity about the network protocol. (Yes, that’s very unusual for me.)
@joytoworld93 @cazabon @yogthos I bought a Pantum laser MFP, it is just fone. I got it from InkStation specifically because they specialise in recycling and refilling cartridges.
