All printer manufacturers *KNOW* that there is a market for refilled toner/ink cartridges. That's why they implement DRM chips into the cartridge. They can already legally:
- Void the warranty on the printer if a 3rd party cartridge is used.
- Claim copyright infringement of the chip on the cartridge.
Lexmark is just being super greedy. They want the sales of those aftermarket cartridges. However, they don't realize that *IF* they win the court case, people can choose to purchase a printer and cartridge from HP, Epson, or Brother.
Perhaps it's time for an Open-Source Hardware Laser Printer. Everyone has a 3D printer now, thanks to RepRap. It would be a nice idea if we could cut all these greedy bastards out of the business altogether.
