NIIMBOT R 40×20 mm white label roll contains 320 self-adhesive rectangular labels on a continuous paper core designed for direct thermal printing. The roll is compatible with Niimbot B21, B21S, B3 and B1S series printers and is intended for printing barcodes, price tags, shipping marks and product identification. Labels are die-cut for easy peel-off and provide a smooth white surface optimized for thermal printheads, allowing clear, legible text and simple black-and-white graphics without the need for ink or toner.
Advantages
The roll offers compatibility with multiple Niimbot portable and desktop models, ensuring plug-and-play use with supported printers. Direct thermal construction removes the requirement for ribbons or cartridges, reducing operating cost and maintenance. Die-cut edges facilitate reliable label separation and application, while the consistent white surface improves barcode readability and scan rates. The compact roll format is convenient for storage and quick replacement.

How to use
Install the label roll into a compatible Niimbot B21, B21S, B3 or B1S printer following the printer’s loading instructions so the printable surface faces the thermal head. Configure label dimensions in the printer settings or companion app to 40 × 20 mm before sending print jobs. Use plain black text or barcode images for best contrast; avoid printing fine grayscale images as direct thermal media is optimized for monochrome output. After printing, peel labels from the backing and apply to clean, dry surfaces to ensure proper adhesion.
Usage recommendations
Store the roll in a cool, dry place away from direct sunlight and high heat to maintain thermal sensitivity. For reliable scanning and long-term readability, apply labels to smooth, non-porous surfaces and avoid abrasive environments. If extended durability is required, consider selecting labels with protective overlaminates or alternative media designed for exposure to heat, oil, or chemicals.
