Remanufactured cartridges for these printers are available. They profit from the first use of the cartridge, but make nothing out of the refilled ones (I've been using them for some time now).
You still pay for it to the company that has decades of hostile practices towards their clients. Their mechanisms are so bad that they even disable valid original cartridges sometimes, good luck with getting that refunded.
But maybe I'm emotional, as that company has been taking premium for a broken experience of so many people I know. I didn't expect such project going for their equipment.
