Could you build this?
Partial The front-end design tool is straightforward, but communicating directly with proprietary thermal label printers via WebUSB/WebBluetooth requires reverse-engineering binary serial protocols (ESC/POS or vendor-specific commands).
What it would actually take: Requires a browser frontend (Canvas/SVG label designer) communicating via WebUSB or Web Bluetooth API. The difficult piece is reverse-engineering the Supvan/Katasymbol proprietary binary packet structure, checksum algorithms, bitmap compression, and printhead movement control from USB packet captures.
