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 paper with permanent hot melt adhesive adheres reliably to corrugated cardboard and paperboard cartons. Once applied, the labels perform from 5°F to 149°F (−15°C to 65°C); apply them at 50°F (10°C) or warmer. Not recommended for PVC surfaces or for bottles 1" / 25mm or smaller in diameter.

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.
