The word air means it receives signals through the air aka wireless. Inkjets are so so cheap now, the printer costs less then the ink. I bought a new Cannon ink jet for $30 when I needed new ink, the cartridges were $55. I bought a new HP printer for $35 instead. I am on my fourth printer being cheaper then buying the ink. But I won't pay more for the ink when I can get a new printer that comes with ink cheaper. If the manufacturer can be ridiculous so can I.
