Originally used to track counterfeiters with the new high resolution printers.
Now they use it to also track leaked movie scripts and other documents.
I'm actually working on a book on digital imaging/printer forensics.
I can usually look at a printed page and tell you what class of printer that was used to print the document.
All have distinctive roller patterns that leave an imprint on the paper.
Plus repetitive defects that not only isolate the pattern to the printer, they isolate it to the roller...................used in repairing printers.

In 2004, when color printers were still somewhat novel, PCWorld magazine published an article headlined: “Government Uses Color Laser Printer Technology to Track Documents.”
It was one of the first news reports on a quiet practice that had been going on for 20 years. It revealed that color printers embed in printed documents coded patterns that contain the printer’s serial number, and the date and time the documents were printed. The patterns are made up of dots, less than a millimeter in diameter and a shade of yellow that, when placed on a white background, cannot be detected by the naked eye.

Gives the investigators a lot more work, but does give up a little bit about yourself.
Could end up with a security cam of you being there that day.

I wonder how it would work with reloaded ammo. There could be multiple codes on one shell.

Law abiding gun owners have absolutely nothing to worry about with this bill in my opinion. That said, I still would be extremely wary to support such a bill. The 1911 was already designed perfectly, and does not need an update such as micro-stamping.

Gosh, I sure hope criminals read and understand this part or the whole idea is useless.

That kind of sums up the chances this legislation would be in any way effective, doesn't it?
