I am trying to print invoices or packing slips that contain customer information that we've required of our customers. We're a school spirit shop and that is the information of which child and classroom that we need to deliver products to. What do I need to add to the code to get this information to appear? Feel like I've scoured these forums for help and can't find a way to contact Shopify support directly.
Attaching a photo of the info for reference to what I need on the slip.
