What does it mean?
Receipt-Layouts define what your printed receipt looks like. You can design your customized Receipts. There are eight different subcategories: Text, Picture, Barcode, VAT, Tickets, Total, Payment and Seperator.
Barcode: The Barcode on the receipt is needed if you want your sellers to be able to cancel a ticket.
Payment: This category shows what kind of payment the customers used (Did they pay cash or with credit card or something else).
What should I do?
Design your receipt. And remember that you need to save every assigned block, otherwise the layout will not be printed.
