This demo video shows a packer using GroovePacker to pack a shipment. In this example the Shipping Labels have all been printed in batches prior to packing. If you need exact shipping weights it's no problem create the shipping label after packing. This would be done in the order manager either by the same user or another team member. They would use the packing slip barcode to display the order, then the weight would be read from the USB scale and the label created.
