Now that I think about it - I've tried this before but decided against it for privacy reasons. I do believe youd need to mark the files as "Available without login" in order to use them in the PDF form. And that was too much of a security risk for our company as the files we wanted were Purchase Orders that could contain personal information from companies. So we decided against moving forward. Though if the files you are wanting to print aren't secure, you could have users mark that "Available without login" box when they are choosing the file on the original transaction. Though, if they forget to - you will get errors when trying to print. So this may be one of those "Is it possible?... yes... Should you do it?... probably not" scenarios
