Orders from the kiosk print according to the settings of the Clover Printers App. In order to link certain items to specific printers, you must configure your printer settings by assigning labels to your printers.
For example, a restaurant may want all drink orders to go to a bar printer, while all food orders go to a kitchen printer. To create this rule, the restaurant would create a "bar printer" and "kitchen printer" label. The label would be attached to the corresponding printer and menu items so Clover knows where to print each item in an order.
