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.
I've been testing the Epson Expression ET-2650 EcoTank All-in-One ($299, epson.com), which is a printer, copier and scanner. The 2650 pumps ink from tanks instead of cartridges. The tanks hold enough ink to print up to 4,000 pages black and 6,500 pages color, which is about two years' worth of use or 20 sets of ink cartridges, according to Epson. The company also says users can save up to 80 percent on ink. So what does the ink cost?
