When a customer does an exchange with their new items scanned in to the original receipt (barcode), the registers will not print a receipt with the new purchases/credit on it. The receipts show up correctly on the digital receipt and in the transaction history but not on the customer's printed receipt. A lot of customers will not walk out without a receipt of their purchases and lots of them don't want a "digital" receipt. This is another flaw with Square Register. Please follow up/fix ASAP.
