| CustomerVisualComponentDataChanged | Any time a customer is added or cleared from the sale this event is called with information about the customer. The ExtraInfo parameters on the customer object can be given values and they will be displayed if those fields have been selected to be displayed in the customer object. |
| PreDisplayReceiptItem | This function is called before the item is displayed in the receipt control. If PreDisplayReceiptItemArgs.DisplayReceiptItem is set to false then the item will not be displayed in the receipt control. |
