Once you have configured ShipStation Connect, you may want to print a test label to ensure everything is set up correctly.
A few things to note about creating a USPS test label:
The selected service must be a USPS service. The test label will be a test label for the service and package type selected for the order.
ShipStation will not create a shipment record and will not send any notifications.
If testing with an active USPS account, no funds will be deducted from the account balance.
To create and print a test label:
Select an order in the grid or open an order's Order Details screen.
Configure the order with a USPS service, package type, and a weight.
Click the drop-down triangle next to the Create + Print Label button.
Select Print through ShipStation Connect and choose the printer you wish to print to.
ShipStation will send the test label to the printer. The resulting label will use the order Ship From and Ship To addresses, but will include the words Sample and Void to indicate it cannot be used for a shipment:
