Confirmation Receipt
This option can assist you in creating additional store and carrier guidelines when customers ship from your store. This portion, you can print for all shipments, or you can choose to print on the fly as needed.
In PostalMate > Tools > PostalMate Settings > Shipping Settings > Confirmation Receipt
If you have this feature active but do not want to automatically print after each shipment made, you will need to manually uncheck the Conf. Receipt button before clicking Finish to get the label only.
