How does the FBI know it was printed? Because the Intercept told them. It could have been screenshots from a phone. It could have been downloaded from some hack. The number of people that viewed a document is going to be a superset of the number of people that viewed and printed a document. And if they're worried someone could access the report outside of their controls, then the set gets even larger. The Intercept only needed to disclose some content and the intelligence report number to get confirmation. Instead, they gave away how they got the report (printed), narrowing it to a set of six, and then they gave away the postmark, narrowing to a set of one. The Intercept burned their source.
