No, this is a thermal printer that uses heat-sensitive labels, so you never need to purchase ink, ribbons, or toner.
For best results and to avoid damaging the print head, it is recommended to use official Niimbot label rolls designed for the B21 series.
The printer is primarily designed for use with the Niimbot mobile app on iOS and Android devices.
Use a cotton swab lightly dampened with 70% isopropyl alcohol and gently wipe the thermal head after the printer has cooled down.
The B21 Pro typically supports labels up to 50mm in width, though you should check your specific app settings for exact dimensions.
Ensure Bluetooth is enabled on your phone and the printer status light is solid. Restart the app and the printer.
Verify that the thermal labels are loaded face down against the print head and that the roll is not installed backward.
Check the label path for any stuck paper fragments and ensure the label roll is properly aligned with the feed guides.
To begin, ensure the B21 Pro is fully charged using the provided USB cable. Download the official Niimbot app from the App Store or Google Play Store, enable Bluetooth on your smartphone, and connect the printer within the app interface. When loading labels, ensure the roll is seated firmly so the sensors can detect the gap between stickers. For maintenance, keep the thermal print head clean by gently wiping it with an isopropyl alcohol swab periodically to prevent adhesive buildup and ensure consistent print quality. Store the printer in a cool, dry environment away from direct sunlight to preserve the lithium battery and thermal sensor integrity.
