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 nor do you need any 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.
