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 have this same model. It’s fantastic. The color isn’t perfectly spot-on, but the contrast is there and it works. I’ve printed off a half dozen print-and-play games as well as three Netrunner sets with clear, legible results.
