If you are using a service where it is shown as "Printer Optnal" the driver will always bring a back up sticky label.
However, you still need to attach two labels with the full delivery address and name on it. This can be a handwritten label, please make sure these labels are securely attached as the driver will stick the tracking label over one of your labels.
We also recommend attaching an additional address label on the inside of the shipment where it will be visible.
For all other services where it advises "Printer required", you must be able to print your labels. There is no exception to this.
