How does your computer know how much ink is in your printer cartridges?

Printers are able to communicate back to your computer nearly the exact amount of ink remaining in one or all of your cartridges. They know this because when ink starts to get low you may notice papers being lighter colored or not as thick of ink. The printer is trying to save ink by doing this. Also once a certain color runs out based on if you have a newer or older printer the printer will try to mix ink colors to create the color you requested if it had ran out.
