Peter Sobot, an engineer at Spotify, noticed something unsettling about his Brother label maker. Though apparently high-tech, under the laptop-style case they still use old-timey printing ribbons that retain an image of everything they ever spit out. Don't discard: destroy!
Thermal label makers solve this problem, but don't offer quite so attractive a result. So I use an old-timey Dymo embosser [Amazon] , with the type wheel and rigid tape: the letterpress of labelmakers.
