Which one fits

The built-in invoice is the right starting point for an Ecwid store that prints a handful of orders a week and is happy with a logo and its business details on the standard layout. It costs nothing extra, can be attached to the order confirmation email, and the orders list prints a batch at once.

Printout Designer is the next step once the document needs to look like the brand, or the store wants a real packing slip, labels and receipts as well. Documents are laid out by dragging fields onto the page, with no HTML or FreeMarker, they print through PrintNode or email themselves when an order reaches a status you choose, and the same setup works on Shopify, BigCommerce and WooCommerce.
