DeaditeBeen using those Epson AIO printers with ink tanks instead of cartridges. Just fill up with the correct ink if a color runs out. Sturdy little printers too
AliceBlueWe can buy the official ink refills in just about every bookstore, office or computer supply store, for as low as USD 5.00 in 70mL bottles that can last a couple of thousand pages, maybe even more.
There are third-party inks that cost a bit less, but with the original ones so cheap it's not worth to risk it.
