Which one fits

Order Printer Pro is the safe default for a Shopify store that needs invoices, packing slips, quotes and credit notes emailed out. It is free under 50 orders a month, handles draft orders, B2B and multi-currency well, has an in-app e-invoicing add-on, and its review count is a strong trust signal on the App Store.

Printout Designer wins when the layout needs to change beyond the supplied settings, since every change happens by dragging fields rather than in Liquid. Packing slips and labels can print themselves on a warehouse printer through PrintNode when an order reaches a status you choose, and the same templates work on BigCommerce, Ecwid and WooCommerce. Printout Designer produces PDF documents only, with no e-invoice XML.
