Order Printer Templates

We can't say enough good things about this app. We were able to modify the Shopify Order Printer app and add the SKU to the invoices, but we could not figure out how to sort by SKU. We downloaded this app and in less than five minutes had a new Invoice template with items sorted by SKU. AND as a bonus (completed unexpected) when we look at the orders in the admin area, all the items are ... sorted by SKU there, too! Brilliant.
