How does direct Bluetooth barcode printing work in the browser?

Using the Web Bluetooth API (on Android/ChromeOS) or Web Serial over paired Bluetooth COM ports (on Windows 11/10), the browser sends raw ESC/POS binary raster data directly to the thermal printer.

Can I print on thermal sticker rolls like 50x25mm, 50x30mm, or 58mm?

Yes. Choose 50x25mm, 50x30mm roll or continuous 58mm/80mm roll presets for direct thermal printing, or select A4/Letter sheets for laser and inkjet label printers.
