Connecting the Printer.

The TSP143IIIU USB Printer from Star Micronics is able to be connected directly to an Android tablet using the USB cable provided with the printer. This allows direct communication between the tablet and the printer.

The printer comes with a USB cable (TypeA-TypeB). The Type A end connects to the back of the printer and the TypeB end connects to a micro USB adaptor similar to the image below. The adaptor connects to the micro USB charging port of your tablet....

...unless your tablet is charged with a USB C cable in which case you'll need to use a USB female to USB C male adaptor similar to the image below.

At the back of the printer there are three ports as shown below.

Plug the USB Type A end of the cable into the middle port as highlighted above. The Type B end plugs into the USB adaptor which plugs into the micro USB port of your tablet.

NB: While the printer is connected to the tablet the tablet cannot be charged.

Connecting the Cash Drawer.

Leading from the back of the cash drawer is a cable the end of which looks a bit like a telephone connection or small Ethernet connection. This is known as an RJ11 cable.

The Cash Drawer is kicked by an electrical impulse from the printer so the cash drawer connects into the printer at the port marked ‘DK’ (Drawer Kick) using this cable which comes out of the back of the cash drawer.
