What goes on an FNSKU label
An FNSKU label has three parts: the FNSKU as a Code 128 barcode with its text below, the product title, and the condition (usually New). The FNSKU starts with X00 for most products and is 10 characters long. Amazon's Seller Central lists the accepted label sizes and print requirements, so check them before a large run.
Why print them on a thermal printer
A thermal printer prints one label at a time on a roll, so there's no wasted sheet of 30 labels when you only need 12, and the bars come out sharp. At 203 dpi the narrowest bar of this label is 2 dots, about 0.25 mm, which scanners read reliably.
Printing many at once
Change ^PQ to the number of copies, for example ^PQ24 for 24 labels of the same product. For several products, fill a template from a spreadsheet with Excel to ZPL.
Questions
Is it free?
Yes: preview and download one file at a time with all its labels, without an account, with no daily limit and no watermark. Paid plans add batches of files, the API and support.
Which barcode does an FNSKU use?
Code 128. In ZPL that is the ^BC command; the ^BY before it sets the width of the bars.
Can I use a label size other than 2 × 1 in?
Yes. Pick another size above and adjust ^PW and ^LL; a common alternative on rolls is 2.25 × 1.25 in.
