Update. 12:10pm, the report disappears while my back is turned. This leaves me to believe that I know to whom I can direct my hatred. But I cannot be sure. Am trying very hard to not walk over to the potential printers' desks to see if the report is there.

Trying trying trying.

Okay, I couldn't help myself. I walked over. No report to be found on that, or adjacent desks.

Problem: Unsolvable.
