Except printer dots are a printer specific serial number. If it was printed on a recent printer then that might be concrete proof of forgery (i.e. if the supposed original document was submitted as evidence as having been contemporaneous of the document's date but was shown to have been printed much more recently because of printer dots).
If you see what I mean...
And I'm not really commenting on the current case (not familiar with it at all)... just positing a possible way to prove a document's date as inaccurate.
