My husband wanted to know how to print with his iPhone 3gs. He doesn’t have a data plan, so it works more as an iPod than a phone. I’ve tethered it to the Network at home, but he couldn’t find a printer.
The reason is that the iPhone looks for an ‘airprint’ printer,which we don’t have. Instead, we have an HP all-in-one on the wireless network. The trick is to get the phone to use it as a network not an airprint.
I found HP has an app called eprint that lets you print on a network.
Also check out Google eprint printing. They list make/models of printers that have this capability.
Naturally, check with the type of phone/tablet you have, then look up the printer make/model online to see if they include apps or services to print.
