In this video, a Canon print cartridge is opened up and revealed not to contain the meagre 11.9 ml (0.4 fl oz) of ink it is advertised. The proposed solution is to buy a printer designed to be manually refilled with bottles of ink (such as the featured Epson EcoTank ET-2850), though it has only been tested briefly.
I agree, $100 for a simple b&w laser printer $200ish for color from them are as much as pretty much anyone needs and they’re stupid fast. Their software and toner management isn’t customer hostile yet at least.
