Is this the same for large format printers? Because they even have region locking. A friend bought his Epson used from Germany for around €7500. During COVID times he needed more ink, but his supplier said it would be a month or two due to supply chain issues. He borrowed a cartridge from a friend who had the correct colour, but his printer wouldn't recognize as it, as our part of Europe is a different region to Germany (ink is the same price in both). He even spoke to unofficial technicians to see if they could unlock it, but the only solution would be replacing the motherboard to change the region.
