Zebra Label 51×25 mm (Core 19 mm) Direct Thermal labels, roll format

Zebra Label 51×25 mm direct thermal labels on a roll with a 19 mm core are designed for use in compatible direct thermal printers. These compact labels print without a ribbon, producing clear text and barcodes for short- to medium-term applications such as shipping tags, product identification, and inventory marking. The roll format and small core make these labels suitable for portable and desktop thermal printers commonly used in retail, logistics and warehousing.

Advantages

Direct thermal construction eliminates the need for a separate ribbon, simplifying media changes and reducing operating supplies. The 51×25 mm size provides a balance between readable barcode area and compact label footprint for small items or tight label spaces. Roll format with a 19 mm core supports printers with small-core spindles and enables use in many portable and compact desktop printers. The thermal receptive surface delivers reliable print contrast for barcode scanning and legible alphanumeric output under typical indoor conditions.

Suitable for

• Shipping and courier labels for small parcels and envelopes

• Inventory and bin labeling in warehouses
• On-the-go printing with mobile thermal printers

How to use

Install the label roll in a compatible direct thermal printer following the printer manufacturer’s instructions for small-core rolls. Ensure media guides are set to align the roll and that the labels feed smoothly. Use appropriate driver or print settings for 51×25 mm label dimensions, selecting direct thermal media type in software to optimize print density and contrast. Avoid exposing printed labels to prolonged heat, sunlight, or oily substances to preserve barcode readability.

Usage recommendations

Store unused rolls in a cool, dry place away from direct sunlight to maintain media sensitivity. For best scanning performance, print at recommended printer resolutions and verify barcodes with a verifier or scanner after initial setup. Use these labels for applications where short- to medium-term durability is acceptable; select thermal transfer labels if long-term resistance to abrasion, chemicals, or heat is required.
