The Zebra Z-Ultimate 2000T White 1.25X0.375 Thermal Transfer Labels 12342/Roll 4/Box 3in-Core PN 10011978 are durable polyester labels designed for electronics identification, asset tracking, laboratory labeling, healthcare applications, inventory management, compliance programs, cable marking, and industrial barcode systems requiring a compact label format and long-lasting performance. These labels provide an economical synthetic labeling solution that delivers superior durability compared to paper labels while maintaining excellent thermal transfer print quality and barcode readability.

Manufactured with Zebra’s Z-Ultimate 2000T White polyester material, these labels are optimized for thermal transfer printing, producing sharp text, barcodes, QR codes, serial numbers, asset identifiers, compliance information, and product data with exceptional image clarity and durability. The value-coated polyester surface ensures dependable ribbon adhesion and consistent print performance throughout high-volume industrial labeling operations.

Each label measures 1.25 x 0.375 inches (31.8 x 9.5 mm), making it ideal for applications where available labeling space is limited. The compact format is particularly well-suited for electronics components, printed circuit boards, cable and wire identification, laboratory containers, medical devices, asset tags, inventory bins, and small equipment labeling.

The labels feature a permanent adhesive designed to provide secure, long-term adhesion to metal, plastic, glass, electronics housings, cables, laboratory containers, shelving, storage bins, equipment surfaces, and a broad range of industrial substrates.

Constructed from durable white polyester, these labels offer excellent resistance to moisture, tearing, abrasion, oils, chemicals, solvents, and environmental exposure. Unlike traditional paper labels, polyester labels maintain their appearance and barcode readability in harsh environments where long-term identification is essential.

Designed for use with compatible Zebra industrial and commercial thermal transfer printers, this configuration utilizes a 3-inch (76.2 mm) core, supporting reliable high-volume printing operations and efficient media handling.

Each roll contains 12,342 labels, and the product ships with 4 rolls per box, providing a total of 49,368 labels per carton, making it an efficient solution for manufacturers, electronics producers, healthcare organizations, laboratories, warehouses, and industrial operations with large-scale labeling requirements.

The polyester print surface delivers outstanding barcode scanning performance, helping improve inventory accuracy, asset visibility, compliance management, product traceability, and operational efficiency.

These labels are ideal for electronics identification, PCB labeling, cable and wire marking, laboratory sample identification, healthcare equipment labeling, inventory control systems, asset tracking programs, compliance labeling, manufacturing environments, and industrial barcode applications requiring a durable miniature label.

Built to Zebra’s exacting consumables standards, the Zebra 10011978 Z-Ultimate 2000T White Labels help maximize printer performance while minimizing printhead wear and media feeding issues.
