Before you can print a receipt after a sale, you must first pair the printer to the Kyte (see how).
After that, once a sale is completed, a screen will appear stating that the sale has been done. At the bottom, you will have the options of "Receipt" or "New Sale". Tap on Receipt.
A preview of the receipt will appear on the screen, and at the bottom you will have the options to send by email, share or print via Bluetooth, you must touch the last one.
All set! the receipt has been printed on your bluetooth printer.
