Over the last 4 years I built a label design and print app using Electron/React. It has 5000+ desktop users and will reach 7 figures in revenue in the next year. I recently launched a new thermal label printer brand named mydpi. Right now I'm selling a 300 DPI direct-thermal version to compete with DYMO and low-end Zebra. In a month I'll launch a thermal-transfer version with bundled ribbon/labels. I never thought I'd play in the "label printer" niche, because honestly, I hate printing labels... but my app makes it possible to easily achieve impressive results. I'm also working on a cloud-based renderer that will make user's designs available as an API that accepts variables for inside the label and returns a rasterized image or the specific-printer-language to print the result.
My life's work...
