This is interesting and something I knew not. Apparently printers print little microdots on the page to document the time it was printed and no telling what else.

Another thing...about this woman...Reality Winners. From the name you know her parents were leftest hippies as has been disclosed. They did a run down of her life accomplishment prior to becoming a traitor...full ride scholarship...speaks three languages...served in the air force. Obviously she's smart but not smart enough to allow her brain to override her political leanings.

Back to the dots....

"These “microdots” are well known to security researchers and civil liberties campaigners. Many colour printers add them to documents without people ever knowing they’re there."

"Based on their positions when plotted against a grid, they denote specific hours, minutes, dates and numbers. Several security experts who decoded the dots came up with the same print time and date."
