Coolnut B21 Inkless Bluetooth Thermal Label Printer — Supports 0.8''-2'' Labels (2 Inch), App-Controlled

Compact Coolnut B21 label maker with inkless thermal printing, compatible with label widths from 0.8'' to 2'' (2 Inch). Built for small businesses and home use, it handles tags and stickers for apparel, crafts, retail, jewelry, addresses, barcodes, shipping/transportation, names, dates, party favors, and seasonal labeling (Christmas, birthdays, Thanksgiving, Father’s Day, Mother’s Day). App & imaging: The upgraded companion app delivers improved image analysis for clearer, more detailed label output. The app supports image recognition and printing, can scan and identify 1/2D code, and allows you to convert photos into editable content for direct printing. Cost & power efficiency: Thermal technology means you only replace label paper—no need to buy ink, toner, or carbon tape any longer. A single battery provides 4 hours of operation, and the printer automatically shuts down after 15 minutes of inactivity to conserve power. This removes ongoing consumable costs and can reduce your printing expenses by 70%. How to use & customization: Connect the B21 to your device via Bluetooth and design labels in the app. Features include automatic template matching, image recognition, and one-touch printing, plus 20+ fonts and 1000+ image materials. You can edit content and adjust layout and position to suit any labeling requirement. Support & returns: Purchases from our store are covered by our return policy. Our customer service team is available to answer questions and provide prompt assistance after you become a valued customer.
