Label Marksman

Label Marksman resizes seller labels for thermal printers. It adds a button inside Amazon Seller Central and Walmart Seller Center, next to the print controls you already use. One press produces a PDF with one label per page, at label size. Amazon Seller Central: - FNSKU item labels — 2 x 1 in. The barcode is redrawn at full height, so it scans better than a label cut out of the 30-up sheet. Works in the Send to Amazon workflow and on the Print Labels for Individual Products page. - Box labels — 4 x 6 in. - Pallet labels — 4 x 6 in. Walmart Seller Center (WFS): - GTIN item labels — 2 x 1 in by default; other sizes can be picked right on the button. Each label carries the GTIN barcode, the GTIN digits and the product name. - Buttons appear on every row of an inbound order, in a product's "..." menu on the inventory list, and on the bar shown when products are selected with checkboxes — set a label count per product and print one batch. Everything runs locally in the browser: no server, no account, no sign-up, no tracking. On Walmart the extension makes no network requests; on Amazon it calls only the label endpoints Seller Central itself uses, under your existing session. Barcodes are never stretched, and every generated barcode is decoded back and verified before the PDF is produced. A label that does not match the expected layout is refused: you get the original file instead of something that may not scan. Marketplaces: Amazon US, CA and MX (CA and MX are less tested; the extension warns on screen). Walmart: seller.walmart.com with WFS. Amazon EU, UK and JP are not supported (A4 sheets). Requirements: a thermal printer for 2 x 1 in and 4 x 6 in labels; an Amazon Professional selling account and/or a Walmart WFS account.
