If you are selling and shipping physical products, you will likely want to include a packing slip with the customer's shipment.
If you are not logged into your WordPress dashboard, begin by logging into WordPress.
Next, select Store Sales from the menu on the left of the dashboard.
Locate the order you wish to print a packing slip for and click on the corresponding link in the Details column to open the order.
In the next page, which shows the details for the individual order, scroll to the bottom of the page and click on the View Packing Slip link.
This will take you to the packing slip for the order where you can then print the page from your browser. Once you have printed the packing slip, simply click the back button in your browser to be returned to the WordPress dashboard.
