USB Interface
The USB interface is compatible with the Universal Serial Bus Specification 1.1. It is a 12 Mbps serial channel using
the Bulk mode with a “B” receptacle as show below. The USB cable must have in one side an “A” plug to connect
in the host, and in the other side an “B” plug to connect in the printer. The printer is self-powered and does not draw
power from the standard type B USB interface cable.
Type “B” Receptacle
Using the USB interface, the printer can be connected to the host even if both parts are powered. The first time you
connect the printer to the host, the operation system will ask for the printer driver. Please download the latest printer
driver from our website (www.bematech.com). For more details please contact your dealer.
