How to choose the best cartridge for Niimbot B21 Pro Green

When selecting an ink for Niimbot B21 Pro Green (i.e., the right thermal labels), we recommend focusing on three things:

• Label size – match it to your use: small for cables, medium for pricing, large for storage and logistics.
• Finish – white labels for maximum contrast; transparent labels for an elegant, minimal look on packaging.
• Shape – rectangular for descriptions and barcodes; round for seals, jars, and decorative tagging.

Common user issues are usually simple to fix: labels not feeding straight (re-seat the roll), faint print (clean the thermal head and confirm you’re using proper thermal labels), or labels peeling on challenging surfaces (choose a finish better suited to the material and ensure the surface is clean and dry). If you tell us what you label—glass, plastic, cardboard, or metal—we’ll help you pick the most practical option.
