Printers are known in IT to be a utter pain in the ass. Most brands are also using a lot of proprietary stuff and it limits interoperability. Drivers for example.

Well known example is about ink cartridges. HP added identification chips on them, so if you want to use an other brand, not HP, to fill your printer, you can't because if no chip is detected despite a cartridge being inserted, the machine will tell you it is not genuine.

Another example with Rycoh. I don't know if their printers still use this method, so take it as an example of capitalist greed more than a current situation. Laser printers are using a sealed container to process waste created during printing. Rycoh had placed a led detector inside to know when it was full and trigger an alert, stopping the machine and request for a change. Good idea in theory but in practice the detector was placed very oddly or on purpose near or in front of dust intake. So it was bathed very quickly in electrostatic dust and thus triggered the alarm very quickly, even if your container was not fully filled. The only way to solve this was to shake your waste storage, hoping it would clean the led enough to keep going for a few days or change it.
