When tendering a transaction, the pos freezes and a receipt does not print. It does give a transaction number, but when trying to view the transaction shows "no receipt to display". If the tender is credit or debit, the card is charged but we have no receipt to give the customer. The items being rang up are normally reduced in inventory, but not always and the sales tax is not always accumulated for that transaction. It also sometimes causes the register the error occurred on not to batch out at the end of the day.
