The Phomemo D550-BT is a 4-inch thermal shipping label printer built for online sellers. It prints 4×6 shipping labels straight from the major marketplaces — Amazon FBA, eBay, Shopify and USPS — so you can clear your dispatch queue fast without ink, ribbons or toner. For anyone running an e-commerce store or marketplace operation, it turns label printing from a chore into a few seconds per order. Made for marketplace sellers Compatible with the platforms online sellers actually use — Amazon FBA, eBay, Shopify and USPS. Download your label as a PDF from the platform, upload, and print. No reformatting, no fighting with templates, no third-party label service. Fast 4×6 shipping output Prints up to 72 standard 4×6 shipping labels per minute (150mm/s), so even a busy sales day or peak-season rush clears quickly. The 203dpi print head produces sharp, scannable barcodes that read first-time on courier and warehouse barcode scanners — no rejected labels, no re-prints. Print without ink Direct thermal means the only thing you ever buy is the label roll — no cartridges or ribbons. For a seller printing dozens or hundreds of labels a week, that's a real saving over an inkjet or laser setup. More than shipping labels Beyond 4×6 dispatch labels, it handles a range of sizes — 2×1, 2×3, 3×3 inch and round stickers — so the same machine prints barcode labels, FBA labels, product tags and "thank you" stickers for your packages. Works with fan-fold stacks and label rolls. Connects to everything Bluetooth printing from iOS and Android phones and tablets via the Labelife app, or USB connection to Windows, Mac, Chrome OS and Linux. Print from your phone between orders or from your desktop while you process them.
