Wireless Rollo is an AirPrint certified device and it can print wirelessly from all operating systems including iPad, iPhone, Android, Mac, Windows, Chromebook, Linux and more!
USB Rollo needs to be plugged into a Mac or Windows computer via a USB cable and does not support printing from other operating systems. 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.
