Ah, noted! With that in mind, did you know that those printer dots are what the team that won the 2011 DARPA Shredder Challenge used to win?

Fun fact: Otavio Good, who led the winning team, learned about the printer dots on this very site. As I recall, he said that the dots were like a map that let them reconstruct the shredded documents.
I would had thought, even then, that this was not only commonly known, but not the sole only annulment/rule among a generally "rules-free" competition, having been rather obvious, especially to the audience these competitions attract.
Thank you for reminding me, and others, how immediate and obvious success can be.
