Printing an order page
If you want to produce a printed copy of an order for your own records, then you can print an order directly from your Shopify admin. When you print an order page, the printed page includes the Timeline comments for that order. Draft orders can't be printed.
Steps:
From your Shopify admin, go to Orders.
Click the order that you want to print.
Click Print > Print order page.
Print or save your order page.
