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 a mobile printer, the OfficeJet 250 also printed quickly â eight pages per minute for black-and-white documents and seven pages per minute for color documents. As a bonus, itâs also much quieter than other mobile printers. The machine uses a tri-color and black cartridge. Printers that use individual cartridges instead of tri-color ones tend to have lower ongoing ink costs, but this HP model also takes high-capacity cartridges, which can keep costs down. The printerâs copier and scanner also reproduced documents faithfully.
