The possibility of reprinting the kitchen orders has also been added. This would be useful when your kitchen printer had not printed the order for some reason (for example, when it ran out of paper). If you open the saved ticket and tap ‘Reprint order’ button from the three dots menu. the kitchen printer will reprint the ticket with the label ‘Reprint’ at the top. You can also reprint the kitchen orders 2 hours after closing the open ticket from the Receipts section. See details:
