I believe that the only code is based on colors.

If your referring to control wiring, then yes there is a standard.
You number your wires & termination points based on your wire line diagram. It all "flows" thru the equipment.
But that is past the point of NEC wiring requirements.

Default Label Printers?

Anyone using a label printer to mark their cables? If so, which features are essential, and which features would you like to see that don't already exist?

Not code, but your best bet is to "reverse address" all your wiring if your in any kind of plant/generation station, etc.

im using a pretty basic brady thermal printer (about 150$), you can choose between many types of self-adhesive tags (i prefer nylon tags). i dont like heatshrink type tags since you have to disconnect wire for identification.
