My label maker made my cable tray labels worse

I spent a Saturday afternoon labeling every cable behind my desk setup with a fancy label maker, printing out neat little tags for each one. Turns out the adhesive on those labels doesnt hold up to the heat from my router and power bricks, so they all curled and fell off within a week. Now I use plain masking tape with a sharpie, folded over the cable, and it stays put for months. Has anyone else had labels peel off on hot equipment, or found a better way to mark cables that actually lasts?

The heat thing is real, but I found out the hard way that the issue isnt just the adhesive, its the label material itself. That plastic film stuff expands and contracts way different than the cable jacket when it gets warm, so it peels off on its own. What worked for me was getting a label maker that prints on heat shrink tube instead. You slide the tube over the cable before you plug it in, hit it with a heat gun or even a lighter for a second, and it shrinks tight around the wire. It never curls, never falls off, and you can still read it a year later. Only catch is you have to do it while youre building the cable, not after its already plugged in. Masking tape and sharpie is honestly still the best retrofit option though, so youre not wrong there.
