And after testing it, I can confidently say this thing here is built to eliminate every pain point that you've ever had with shipping labels. You see, this printer is totally different. It's thermal. No ink, no toner, no ribbons, ever. Thermal printing means you only buy labels. That's it. You'll save hundreds of dollars a year eliminating messy cartridges.
