It was previously necessary to add an Order Number barcode to the packing slip in order for GroovePacker to display the order for barcode packing QC. GroovePacker can now read the ShipStation "scan to view" barcode or the order number barcode interchangably. Here are the steps to enable this option:
Click on Settings > System Settings > Scan & Pack Options, then select the Packing Slip option from the Cue Orders dropdown.
