Direct Thermal Labels 4×6″ Zebra Compatible White Shipping Labels – 102mm x 150mm – 250 Labels/Roll (25mm Core)

Short answer: Yes — these are standard 4″×6″ direct-thermal shipping labels and are built to work with most desktop direct-thermal printers (including Zebra Technologies, Rollo and Dymo models). If your printer accepts direct-thermal rolls and the roll core fits, you’re good to go.

Nope — these are direct thermal labels, meaning the paper is heat-sensitive and the printer head creates the image by heat alone. No ribbon, toner, or ink required — which keeps running costs lower but also affects durability (see FAQ #5).

Yes — 4×6 (102×150 mm) is the de facto carrier shipping-label size and prints barcodes and addresses that standard carrier scanners read fine. They’re commonly sold and advertised specifically as shipping labels for carriers like USPS, UPS and DHL. Just be sure your printer settings (page size, orientation, and margin) are set to 4×6.

“25 mm core” is the inner cardboard tube diameter (≈0.98 in). Different printers expect different core sizes (some use 25 mm / 1″, others use 76 mm / 3″). Check your printer’s spec or look at an existing roll — if the printer spindle matches ~25 mm, the roll will fit. If not, you’ll need labels on the correct core. Many product pages explicitly list the core so you can match it.

Direct-thermal prints are sensitive to heat, sunlight, oils and abrasion. In typical indoor shipping use they’re usually fine for the short term — most sources give a practical lifespan around 6–12 months (longer in cool, dark storage; shorter if exposed to heat/UV). If you need archival or outdoor durability, choose thermal-transfer labels (with ribbon) or a top-coated direct-thermal grade. Store rolls in a cool, dry place to maximize life.

No — these rolls are made for direct-thermal printers only. Laser or inkjet printers won’t print correctly and may damage the labels. Also, plain direct-thermal labels aren’t ideal for long-term outdoor exposure (they can fade or blacken with heat/UV). For long-term or outdoor labels, look for thermal-transfer + appropriate ribbon or weatherproof/synthetic label materials.
