Seiko Instruments 58mm x 40m Thermal Paper Roll for MP-B20 Mobile Printer, Phenol-Free, 40mm Roll Diameter SII-Bon-58-20-40

For mobile POS and receipt printing in retail, hospitality, and field service, this Seiko Instruments thermal paper roll keeps your MP-B20 mobile printer running with crisp, clear receipts. The 58 mm width and 40 m length fit standard mobile receipt formats, while the 40 mm roll diameter ensures a proper fit inside the printer compartment. The paper is phenol-free and BPA-free, making it a safer choice for high-volume handling. Direct thermal printing means no ink or ribbons are required—just heat from the print head produces sharp black text on white paper. Store in a dry, cool place away from direct sunlight to maintain print quality and shelf life.
