Select all the foods ordered then swipe the screen from the left to the right and select “Process receipt”. This will print the order on the kitchen printer. If, in your order list, you have some items that do not need to be prepared by the staff in the kitchen then swipe your finger on the item line then select the “complete button” which is the last one  and press ok to the dialogue box. If you add more items after having printed the order, then only the newly added item will be printed after you select the “Process receipt” tab.
