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.
Really hard to justify its cost if your ever print like, 50 pages a year.
If you print rarely inkjet is going to dry out and stop working, making them even more expensive and annoying.
My printer was constantly getting clogged because I only print every few months. I was literally buying a new ink cartridge every time. Laser printers can be left quiet indefinitely without wasting ink/toner, they’re much better for intermittent use.
