How do I create a return label that was approved by the merchant?

I'm sorry, but can you add more details regarding this return label question? I would like to understand it more so I can give you the correct steps or provide you solutions or workarounds.

Our forms can send an autoresponder email to the submitter. If you would like submitters to print something after they submit your form, there is also the PDF Attachment in it. However, if there is a workflow that needs to be followed, then the solution would be a little bit different.
