So as I understand it, the way that air print works is via one of two ways. The first is to have a printer hooked up to your Mac or pc, which is connected to your network. So basically you are printing through your home computer. The second way is to have one of the new HP e-printers. This option, as I understand it, is the only truly wireless printing option. This is because the e-printer is online, and on your network at all times. I believe the e-printers also work by emailing your document/pic to the printer? Or can you, while on the network, just hit print and not have to email it? Can anyone with a better understanding of how airprint works, and what our options are, add to or correct what I have said?
