2002 has addressed this, in Article 110.22, but left it unclear of what is considered sufficient durability, Basicaly left judgement up to the (AHJ). I presonally carry a label maker that in my opinion looks more perfessional, than a marker. I have seen marker indentification look perfessional, than I have seen them also look like caveman art. Some guys even use the old press lettering (one click at a time) device. Works OK. The ones now I'm seeing that I like is printed labels with a clear sticky back envelope stuck to the disconnect, and you can make them from your own PC. Then change them latter if need be.
