Mrs. NavySEAL reminded me of one important thing about the IBM executive. The letters would continually become out of alignment due to the fragile nature of the key arms. Only a technician could correct the seeming floating letters.
As MineralMan also pointed out, getting such good registration across several paragraphs of type, on by now probably hundreds of printers/machines, is so improbable that it is reasonable to say it is impossible.
A similar appearance can be created, but not similarity with the precision exhibited with the forgeries.
