I don’t agree with the term this article uses.
Can cryptography prevent printer-ink piracy?
How can printer manufactures get a way with requiring you to use only printer ink they make when you own their printer? This crosses the line. They already cancel the warranty, if you use other ink. This new trick will stop the printer from working. How is this any different than a after market manufacturer supplying parts for your car or PlayStation after you own the item. The courts have upheld the rights of people to buy parts from other manufactures to maintain equipment, so how is a printer different. The companies will be forcing a monopoly on the ink supply. I’m not concerned that one use is to stop people from selling mislabeled cartridges. The main purpose is to eliminate competition in the ink supplier market. I’m looking for how this is or isn’t legal people.
