Rollo requires a USB connection.
Typically Rollo is plugged into a Mac or a Windows computer via USB.
Once it is connected to a PC or Mac, you can "share" it across your wired or wireless network via Windows' or Mac's built-in share printer feature.
Our customers have successfully connected Rollo 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 Rollo.
