Hi James,
The WooCommerce Print Invoices & Packing Lists plugin ($49) allows you to easily print invoices, single order packing lists, and multi-order pick lists for orders right from the orders listing page. You can print individual orders, or bulk print invoices, packing, or pick lists with a couple clicks. This is a helpful timesaver to help you package and ship orders, and it lets you include invoices with policies in your shipments.
With this plugin, you can also customize the information that gets printed on the invoice/packing list. You can set custom company details, custom info which can include for example returns policy, custom footer content, and more.
Hope this helps!
