Unique Sequential Number in each printed copy of a document
Documents such as petitions are often numbered. This is so a set of identical documents assigned to different people can be tracked, to ensure that all pages are accounted for. Being able to print a unique sequential number in the footer of each page would be a tremendous enhancement. For example, if I were printing 500 pages of a 2-page document in duplex mode, I would want a serial number to appear on the footer of the first page in this sequence: 1001, 1002, 1003.....1499, 1500.
