By default, the button is set to Create + Print Label, so you can create the label and initiate the print action in a single click. If you use this in conjunction with the Default Printer setting and ShipStation Connect, one click will both create and print the label.
If you do not wish to print the label right away, but rather create a group of labels first, then print them later, you may wish to change the default state of the button to just Create Label so you don't have to select it from the button's drop-down each time.

To change the default button state:
And that's it! When you return to your Orders and Shipping tabs, the default button for creating labels should be updated.
This setting will determine what types of barcodes Scan to Verify will recognize for your products.
You can select UPC, Item SKU, and Fulfillment SKU.

These options correspond with the product fields in ShipStation. For example, for Scan to Verify to recognize a UPC barcode, the UPC number must be saved in the product default's UPC field.
The Item SKU corresponds to the product's SKU field and the Fulfillment SKU corresponds to the Fulfillment SKU field in the Product Details in ShipStation.
To learn how to add the UPC and Fulfillment SKUs to a product in ShipStation, review the Add UPCs and Fulfillment SKUs section of the Scan to Verify & Print article.
