It can be anywhere on the length of cord. The one I had originally had the printing 3" away from one endpiece, the one I was given as a replacement had the printing dead center between the two endpieces. Looks like the manufacturer is just printing at a specific interval and wherever the shielding gets cut is where it gets cut.
Look carefully, it should be there. Some report that they have no printing at all, but I think that it merely rubbed off. You can walk into an Apple store with your cord and get an immediate replacement, just do that and you'll know your cord is safe, no need to take the risk.
