[Supported interface type]
- USB

The Android device must work as USB host to control the printer device. For example, you will need a so-called USB OTG (On-The-Go) adapter, which has a micro USB or Type-C male connector on the Android side (depending on your Android device) and a Type-A female connector on the other side. Then you can connect a regular USB cable for printer which has a Type-A male and Type-B male to connect to a printer.
