There's apparently a decent third-party market for such things, the key is you have to possess a label maker that will do reverse printing (mine will). And you can 'fake out' the printer to let it use non-standard cartridges by covering up some of the holes on the cartridge.
The labeling is on the outside of the tube, so it not as scratch-resistant as the normal way those kinds of labels are made (to the backside of the tape). So you have to use the tape AND clear heat shrink over that if you're going to put it in a place with wear potential. If you're going to do that then you might as well just use some narrow regular tape and clear shrink over that, but it's more fiddly that way to peel the regular tape, stick, cover and shrink it.
