You can print orders in bulk using our Order Printer app! Let me take you through the steps:
1. You will need to select your orders in bulk:
There is a master checkbox at the top of most item lists. You can click the master checkbox to select every list item on a page:
2. When you have selected your list items, you can choose a bulk action to perform.

Hope this is helpful! Our support is available 24/7 if you have any other questions.
There are plenty Apps existing to basically print invoices in bulk, which you can find on the shopify App Store.
We're using personal print for our invoices because it lets us smartly customize our invoices, and they can then be downloaded directly from the Shopify orders' list page. It's incredibly the only App we've found with a drag and drop invoice builder that truly let us build what we wanted.
We're also using it to send some automated personalized thank you notes to our customers for about a year, and we love it for that!
