Order Printer App Shopify POS Pro Customer Informtion

[takengomattress]

In Shopify Pro, I am using the order printer app to print receipts. When generating a POS Pro order you can add a customer to the order. When I print using the Order Printer app it does not carry customer information over the the receipt. What coding do I need to add to the template to grab this information?

I have tried several variables but none are working.
