I’ve thought about just putting it on the connector itself. It may look stupid though.
Visually, if it's something I'm going to be staring at on a daily basis, I like this much better than having tags hanging off of the cable. Tip: consider white-on-black labels.
The labels have been plenty durable in my experience, but if you need extra durability, you could probably just brush some lacquer over it with a Q-tip.
One big differentiator between various Brother models that's not immediately obvious is the tape sizes they accept. The cheaper models don't accept the fatter 24mm/1" labels, gotta step up to the $99ish models for that.
