I am going to buy a new printer. And I would like to buy one that is the most compatible with airprint's capabilities. I have a basic (and probably flawed) understanding of how it works, and would prefer to not have a "network" setup, ie my pc has to be on to run the printer through. I want to be able to print as wirelessly as possible. So do I want a wifi printer, or do I want one of the hp eprinters, or am I missing something and they are basically the same? Thanks for the insight.
