RETAIL STORE FAQ

Before you choose your Retail Kit

Does the B21 White require ribbon?

No. B21 White uses direct thermal printing. Compatible label rolls are the only printing consumable.

Which labels are best for retail work?

50×30 mm White is the primary everyday retail size for products, shelves, and general pricing. Add 40×20 mm White for compact price and barcode labels, and 50×50 mm Round for boutique branding, gifts, promotions, and packaging.

Can I use M2 labels in the B21 White?

Do not assume cross-compatibility. M2 is a thermal-transfer system with its own labels and ribbons. Buy only refills explicitly confirmed for B21 and compatible B-Series printers.

Why choose B21 White for retail use?

B21 White combines a recognizable retail-style design with mobile Bluetooth printing and a practical B-Series label range for pricing, product labels, shelves, barcodes, promotions, and packaging.

What warranty and return support is included?

NIIMBOT printers include a 1-year warranty and Office Koala offers 30-day returns, subject to the store policy.
