I do wonder whose fault it is though. Companies exist to make a profit. I'm sure some extra returns are caused by 3rd party laser and ink cartridges. I've personally seen a 3rd party toner cart have some kind of internal failure and strip the drive gear in the printer. Just like the EU is requiring USB-c to charge a phone, governments should consider requiring a standard ink and toner cartridge. It would reduce inventories, increase volumes, amortize R&D over a greater number of printers, and increase competition for the standard cartridge. The standards committee (like the USB committee) could set the standards, have branding/labeling for particular features, and talk with industry about desirable features for the next generation. I just hope they avoid doing something insanely stupid like making dozens of USB-c cables, visually identical, but incompatible.
