It turns out that printers can easily give you away. Reality Winner (I thought that was a codename/screenname at first…), the Air Force Veteran charged with mailing classified material to a news outlet, was caught by the NSA and Feds due to how certain printers function: apparently, many print a pattern of yellow dots that, when decoded, can offer insight on who created a document, and when. Being that agencies log any and all hardware usage, it was easy for the government to figure out who crossed them.
...the arrest warrant request for an NSA contractor named "Reality Winner" was published, showing how they tracked her down because she had printed out the documents and sent them to The Intercept. The document posted by the Intercept isn't the original PDF file, but a PDF containing the pictures of the printed version that was then later scanned in. The problem is that most new printers print nearly invisibly yellow dots that track down exactly when and where documents, any document, is printed. Because the NSA logs all printing jobs on its printers, it can use this to match up precisely who printed the document.
