Print FNSKU Labels on a Thermal Printer

Print Amazon FNSKU labels on your thermal printer from the PDF Seller Central gives you. Upload it here to get ZPL, the Zebra printer language, so the label prints at its true size without a driver scaling the barcode.

No PDF yet? Make one label with the FNSKU label generator. Roll with two labels across? See 2-up thermal labels.

Upload a label to convert

Drag and drop a PDF document here, or click to browse your computer.

Several labels? Drop all the files at once, or a ZIP.

Note on Watermarks: Any single label converts free with a watermark, so use it to test the fit, not for inventory you'll ship. Converting a whole file is part of LabelZoom Pro.

ZPL carries the label's own size, so there's no fit-to-page setting to get wrong.

A 30-up sheet comes apart into single labels that feed from a roll.

A shipment with hundreds of the same label goes out as one label and a print quantity.

How to print FNSKU labels on a thermal printer

  1. 1

    In Seller Central, print item labels for your shipment. If it offers a thermal size that matches your roll, choose that, and download the PDF.

  2. 2

    Upload the PDF above in the default mode. If the converter offers Split pages… for a sheet, accept it. Otherwise, set Label stock to your roll, or to Same as your PDF pages.

  3. 3

    Convert one label and scan it. When it reads correctly, convert all labels and send the ZPL to your printer.

What to do with each Amazon label file

Amazon's label files come in several shapes. The right route depends on the one you have.

A sheet label is cut out at its own size and isn't shrunk. A 2.625 in wide label on a 2 in roll loses its right side, so for a narrower roll, ask Seller Central for that thermal size instead of a sheet.

These are the sheet sizes Seller Central offers, as reported by sellers, plus common rolls. Amazon's current requirements are in Seller Central, and LabelZoom can't confirm that a label meets them.

Why this matters more in 2026

Printing item labels is now routine for many US sellers. Amazon's US prep and labeling services ended on January 1, 2026, and since March 31, 2026, the end of commingling means sellers without the Brand Representative role sticker each unit they ship in. That's as of October 2026, so check Seller Central for your account. Amazon's own thermal PDF is a sound choice if it prints cleanly on your setup. Use ZPL if driver scaling keeps getting in the way, or if you print from a warehouse system.

Frequently Asked Questions

Answers about printing Amazon item labels on thermal printers.

Can I print FNSKU labels on a thermal printer?
Yes. Seller Central can produce item labels in thermal sizes as a PDF, which a thermal printer's driver can print. LabelZoom turns that PDF, or a 30-up sheet, into ZPL so a Zebra printer draws the label itself, with no driver scaling.
How do I print a 30-up Amazon sheet on a roll?
Upload the PDF and choose Split pages… when the converter offers it. It finds the 30 labels and converts each one on its own. A label on that sheet is 2.625 × 1 in, so print it on a 2.625 × 1 in roll. The converter cuts the label out at its size and doesn't shrink it, so a 2 × 1 in roll loses the right side.
What size is an FNSKU label?
Sellers report Amazon's sheets ranging from 48.5 × 25.4 mm on the 44-up sheet to 63.5 × 38.1 mm on the 21-up sheet, and the 30-up Letter sheet is 2.625 × 1 in. Sellers quoting Amazon's guidance give a range from 1 × 2 in to 2 × 3 in. A 2 × 1 in roll is a common thermal choice. Check Seller Central for the current requirements.
Do I need a Zebra printer?
You need a printer that reads ZPL for the ZPL output, such as a Zebra or a ZPL-compatible model. Check your printer's manual. If yours doesn't read ZPL, print Amazon's thermal PDF through the printer's driver at 100%.
Why do my FNSKU labels print too small or off-center?
A driver scaling the PDF is the usual cause: the page is fitted to the paper size set in the driver, not the label. Set the driver's paper size to your label and turn off fit-to-page. ZPL avoids the step altogether, because the size is in the file.
What about FBA box labels?
Amazon has offered box labels in a 4 × 6 in thermal format for North America since December 2019. If you have one on Letter or A4 paper, upload it and choose Crop to the label, which places it on a 4 × 6 in or 100 × 150 mm label. Sellers report that AWD labels come as A4 only.
Is this free?
Any single label converts free, with a watermark, so you can test the fit. Converting a whole file is part of LabelZoom Pro, which removes the watermark. The FNSKU label generator makes ZPL with no watermark, one FNSKU at a time.
