USB On The Go

USB On-The-Go (OTG) is a technology that allows a specially configured USB port to act as both a device port and a host port. A device port is what is normally thought of when users think of a USB device – one that connects to a computer or hub to enable communication with the printer. A USB host port is the port a user would typically find on a computer, and to which they would connect devices.


The USB OTG port, with the use of a special cable, enables the port to act either as a host or a device. This cable also provides a standard USB port to which a cable or hub can be connected.


All ZQ500™ models implement the USB OTG port on the printer itself.
