The average black printer cartridge uses 8 ml of ink (the end of your pinkie) I paid $30 a litre for the stuff and used a standard vet hypo to refill. The best we ever did was a dozen refills of an HP60. Costco can refill most with their $30,000 machine for about $10. You get a new chip, so printer thinks you have a new cartridge and often there is more ink than factory. Professional refillers (hard to find) will ultrasonic clean & vacuum the heads and run test strips. (Except Canon, ultrasonic destroys them) All I have is lasers and still running one cartridge for two years now. You can find aftermarket color on eBay but most don’t have much powder.Most printers come with a Starter which is half fill, you can tell by weighing.
