Seller Central’s 30-up PDF
Your 2.25 × 1.25 in roll, shown at real size

Barcodes are rebuilt crisp for your printer’s dots, not stretched. Titles are trimmed the way Amazon trims them.

Print one test label. Measure two gaps. Done for good.

The test label has a frame exactly 2 mm inside each edge. Tell Prepline how wide the left and top gaps came out, and every label after that lands in the middle. Saved for each printer.

Questions

Which PDFs can I drop in?

The item label PDF from Seller Central in any layout: 30-up Letter sheets (Avery 5160), the A4 sheets (21, 24, 27, 40 and 44 up) and thermal pages with one label each. FBA box labels and 4 × 6 shipping labels work too; those are copied exactly as they are. Scanned or image-only PDFs are read from the ink.

Why do my labels print with the sides cut off, or tiny?

Usually the print dialog is scaling a Letter-size page onto a small label, or the paper size is wrong. Prepline makes each PDF page exactly your label size and tells you the three settings to use: the label size as paper, Scale 100%, margins None. The test label fixes the last millimetre.

Will the warehouse scan these barcodes?

Prepline draws every bar as a whole number of printer dots (2 dots at 203 dpi, about 10 mil), so thermal printers don’t smear bars into each other. Follow Amazon’s label rules and scan your first test label with any phone barcode app before a full run.

Is Prepline approved by Amazon?

No. Prepline is an independent tool for Amazon sellers and isn’t affiliated with Amazon or Walmart. It follows Amazon’s published item label specs: 1 × 2 in to 2 × 3 in, barcode, FNSKU, title and condition.

Can I use a half-used sheet of 30?

Yes. Tap the first empty sticker on the sheet preview (say label 13) and printing starts there.

Excel removed the leading zeros from my UPCs. Now what?

Paste the list anyway. Every cell is read as text, and when an 11-digit number becomes a valid UPC with a zero in front (the check digit proves it), Prepline puts the zero back and tells you. Numbers Excel turned into 1.23E+11 are flagged, because those digits are gone.

Does it do Walmart WFS labels?

Yes, with Pro. Walmart wants a UPC (12 digits) or GTIN-14 on each unit, not an FNSKU and not an EAN. Switch the job to Walmart and Prepline checks every code against that rule.

Are my files uploaded?

No. Prepline reads the PDF and builds the new one inside your browser. Your product list never leaves the computer, and after the first visit it works with the Wi-Fi off.

Does Pro renew automatically?

Yes: monthly at $9 or yearly at $79, until you cancel. Cancel online anytime and keep Pro to the end of the period you paid for. The 7-day Shipment Pass ($5) never renews.

Can I use it on the PC next to my printer?

Yes. After you pay you get a license key. Paste it into Prepline on any other computer and Pro is on there too. No account needed.

Shipment going out today?
