>She downloaded/retrieved a document, then printed it, then scanned it again and mailed it to The Intercept?
I think that's just people misunderstanding the "mailed", it really means physical mail here.
>Some stories claim she was caught because access to the document was logged, others point to the dots and printer logging.
The legal paperwork claims that she was caught due to the audit logs and her previous unrelated communications with The Intercept. I don't believe there's any reason to doubt that, the dots probably didn't play a part there.
>But printing a document and then scanning it again would not make sense, would it?
The document was probably just printed and mailed.
