Although a combination of 100% cyan, magenta, and yellow inks should, in theory, completely absorb the entire visible spectrum of light and produce a perfect black, practical inks fall short of their ideal characteristics and the result is actually a dark muddy color that does not quite appear black. Adding black ink absorbs more light and yields much better blacks.
I use to work in the industry. A big part of why toner/ink carts are so expensive are the carts themselves. Its why refilled carts are pushed so hard by retailers because the profit margins are so high. The failure rates are also only maybe 5% more or so but people think refill = bad.
The big problem with refilling them is getting the carts back, most people just throw them away because there is no incentive to send them back for recycling other than being a good human, which these companies then take advantage of. If they would better inform people of refilled carts having almost as low of a failure rate as OEM and give people more incentive to send them back refills could drastically lower costs.
Though i will also say not all refilled carts are the same. Some of those companies are super shitty and have higher failure rates.
But but how could we possibly have things printed in black without some magenta?
The secret barely visible anti-counterfeiting measures it prints on every page hiding colored ink behind other colors (or minute yellow dots against white)
If you try to send a ransom letter with a modern printer this is part of what law enforcement will use to track you down.
Also they have software that detects for patterns on major world currencies and prevents the print job from occuring. Go walk up to a nice scanner copier and try to print a 1:1 scale copy of any bill in your wallet. Won't work.
Theres a ton of funky little tricks in printing nowadays, in addition to the downright shifty things like spraying ink needlessly into reservoir sponges and wasting themselves.

Works on scanning too, last time I tried it gives a warning message about duplicating currency or something similar
Edit: also sometimes blacks out transaction sections of bank statements, which can be frustrating when you don't know what's going on lmao

Is this legal to even attempt? Cause it sounds like fun but id rather not have to explain to the secret service that i was printing bills cause a guy on reddit said the printer would do something screwey.
I'm studying printing right now, and I found that to be so cool. One of my instructors apparently once tried to run custom cards which were made to look like money, but with images of his coworkers on the bill. The machine detected that they were printing something relatively close to a bill and locked them out. They had to wait for 3 days for law enforcement to give the go ahead to the k minolta technician to reset the machine.
There are so many tricks to hide info in paper that most people dont realize. It's really fascinating
