Turn your printer into a wireless hub, allowing it to connect to WiFi with one other peripheral, featuring a compact design that fits perfectly inside the mC-Print31W and TSP143IV or on top of the mC-Print21W. The MCW10 provides a wireless connection to the printer and any networkable 3rd party devices such as payment terminals. Able to connect up to two devices at once, the MCW10 easily configures to the router using the simple Star Setup Utility App for iOS and Android.
