Will these 4" x 6" shipping labels work with my printer?

These 4" x 6" labels on 1" cores are the standard shipping label format and fit 4-inch wide thermal printers including Zebra ZD220, ZD230, ZD410, ZD411, ZD420, ZD421, ZD500, ZT230, GK420d, GX420d, ZP450, ZP500, Datamax E-Class Mark III, TSC TDP-225, TTP-244, TE200, TE210, Sato CG408, WS408, GoDex, Brother QL-1100/1110NWB, and Rollo printers. They calibrate automatically on most label printers — set label width and gap sensing if your printer was previously configured for a different size.

Will these print labels from USPS, FedEx, UPS, Amazon, Etsy, eBay, and Shopify?

Yes. 4" x 6" is the universal shipping label size used across USPS Click-N-Ship, Stamps.com, Endicia, ShipStation, Pirate Ship, FedEx Ship Manager, UPS WorldShip, Amazon Seller Central, Etsy Shipping Labels, eBay Labels, Shopify Shipping, and ShippingEasy. The labels are rated for thermal head printing of barcodes, QR codes, address blocks, and tracking numbers from any of these carriers and platforms.

Are the labels durable enough to survive shipping handling?

Yes. The 75gsm direct thermal facestock with permanent hotmelt adhesive bonds to cardboard, polybag mailers, padded envelopes, and most shipping surfaces. The labels are water, oil, and scratch resistant for the duration of typical shipping transit. Service temperature is 5°F to 149°F (-15°C to 65°C). For extended outdoor storage or refrigerated/frozen shipping, thermal transfer labels with a ribbon offer better long-term durability.

No. These are direct thermal labels — the printer's thermal head creates the image directly on the heat-sensitive label. Ribbons are only needed for thermal transfer printers.
