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.

Inkjet printers can be operated normally with a modified sine wave inverter rated to handle the printers wattage requirement.
