Phomemo requires a USB connection.
Typically, Phomemo is plugged into a Mac or a Windows computer via a USB cable.
Once it is connected to a PC or Mac, you can "share" it across your wired or wireless network via the Windows or Mac built-in share printer feature.
Our customers have successfully connected Phomemo to Airport Express as well as other third-party USB wireless printer servers such as this USB Printer Server.
Please note third-party hardware is not directly supported or endorsed by Phomemo.
