We added a new feature to our web-to-print extension for Magento that allows order confirmation emails sent to customers to contain preview images of their orders. Since release 188.8.131.52.5 (beta) of the extension, when a customer places an order on a web-to-print product, the email notification that is automatically sent out by Magento will contain preview images of the order.
Links to web-to-print output files
If the template is set to allow customers to download the generated output files, the notification email will also contain links to those output files. Customers will now be able to reach and download the generated files from the email they received after successfully placing an order. No need to login to their customer account in your store in order to get their files.
