Order Printer Pro is an app designed to allow you to print and download PDF documents from your Shopify admin. It also features an "Automated PDF" option, which enables you to include a PDF download link in emails that your Shopify store already sends to customers. This simple one-time setup means your customers always have easy access to their invoices and other documents.
There are three main reasons for using a download link:
It allows you to provide needed documents without the customer receiving additional or duplicate emails, which can be confusing or hard to find again later.
A PDF download link in the emails Shopify sends means there is no additional setup required for you to receive the email, or another email you need to customize and maintain.
Shopify does not support attachments in the emails that it sends.
You can set up the automated PDF link by following the instructions provided in this article.
