Printer ink, the simple black liquid that people have been using for centuries. How much does Ink really cost? Weâll take an HP 564 black cartridge. This particular cartridge can hold 12 ML of ink. OEM priced at $12.99, we can factor that the ink inside is worth 92 cents per ML.
For example, the standard capacity Epson SX445W colour cartridges contain 3.5ml of ink compared to 7.0ml in the high capacity cartridges. This means that you get twice the amount of ink without paying twice as much for the cartridge.
