Star released this, one of a kind, USB POS printer that works with the iPad (and WaiterOne) : the Star TSP143IIIU. The beauty about this printer is that you don’t need a network and (!) you don’t need any networking nor IT skills to install it.
1. Connect your printer to your iPad with your lightning cable (USB on printer side, lightning on iPad side) :
2. In WaiterOne go to data -> printer -> bill -> general -> host and enter : USB:TSP100
3. In the same settings as above, select Star Raster Mode as type printer
All done! Push the QR Code next of the host address in WaiterOne and a small ticket should be printed.
Thanks to Star EMEA for borrowing me this printer.
