USB interface (optional)
The KC-4112 has an USB interface 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 shown 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 in the host even if both parts are powered. The first time
you connect the printer in the host, the operational system will ask for the printer driver that you received with
the printer. For more details please contact you dealer.
