If you receive the error “FedEx ERROR: Invalid values in Label Stock Type for LABEL” when trying to book a shipment, this is because the Doc-Tab labels do not work with the Zebra format turned on. Follow the steps below to resolve the issue.
Click the Settings tab.
Under “User Settings” select “Printer Setup”.
Uncheck the option for “Use Zebra Printer format when available and connected to WebshipLink”, and "Save Changes".
Note: These changes will ONLY apply to new shipments, the changes will not apply to already booked shipments in the History/Track screen. You may also want to refresh your browser if you have not done so after initially changing the printer settings in order for the changes to apply.
