[nznog] So what're people using to label ethernet cables these days?

I've got a project underway with a large amount of fresh-install ethernet cabling and i'd like to 'do it right' with respects to cable labelling. The old does-everything Dymo Label Printer is doable, for a while, but in datacentre environments the labels degrade and fall off eventually, which isn't ideal. I've also used 'kabelflags' before but I would prefer something I can print with a machine, I think. That said i'd be interested in what people are doing, or what they 'should' be doing... ?
