Complete Guide to Shipping Label Printing
The full guide to shipping label printing: marketplace formats, paper sizes, thermal printers, cropping, and barcode best practices.
What Is a Shipping Label?
A shipping label carries everything a courier needs to deliver your package: the destination and return addresses, a scannable barcode or QR code, and the order or tracking number. Marketplaces generate these labels automatically when you process an order.
Printing them well matters because a damaged or unscannable barcode can delay every shipment it's attached to.
Marketplace Label Formats Compared
Flipkart, Meesho and Amazon each generate labels with their own layout, but all share one trait: they ship with large white margins. Cropping these margins is the key to cheap, efficient printing across every marketplace.
Amazon often bundles labels together with invoices and packing slips in a single PDF, so separating the label from the invoice before printing is an important extra step.
A4 vs 4x6 Thermal: Which Is Right for You?
A4 printing works on printers you already own and is fine for low volumes — especially when you arrange four labels per page. Thermal 4x6 printing is the professional choice for higher volume: no ink, cheaper per label, and faster to apply to parcels.
Many sellers start on A4 and move to thermal once they pass roughly 20-30 orders a day.
The Cropping Workflow
Upload the marketplace label PDF to the matching crop tool, let it auto-detect the label boundaries, choose your output layout (single, 4-up or thermal size), and download the print-ready PDF.
The whole workflow takes seconds per batch and keeps your barcodes at full resolution.
Barcode Best Practices
Print at 100% scale, never 'Fit to Page'. Keep the barcode area clean of folds, tape and creases. Use matte label paper and enough contrast for reliable scans.
If a barcode ever fails to scan, reprint immediately rather than trying to re-use the label — a clean label is cheaper than a lost shipment.
Track Your Savings
Once you switch to cropped 4-up A4 printing or thermal, track your paper and ink purchases for a month. Most sellers see their printing costs drop by 50-75%, which quickly compounds as order volume grows.
Frequently Asked Questions
What size is a standard shipping label?+
The most common shipping label size is 4x6 inches (100x150 mm). Labels can also print one-to-four per A4 page on a regular printer after cropping.
Can I print shipping labels on plain A4 paper?+
Yes. Courier partners accept A4 labels as long as the barcode prints at 100% scale with enough contrast to scan.
Do I need a thermal printer to sell online?+
No. You can start with a regular printer using a 4-labels-per-A4 layout. Thermal printers become worth it at higher order volumes because they eliminate ink costs.
Why do shipping labels fail to scan?+
Common causes are printing at reduced scale, damaged or creased barcodes, low contrast, or cropping that cuts into the barcode. Print at 100% and keep the barcode area clean.
How do I print Amazon labels without the invoice?+
Use the Amazon label crop tool. It separates shipping labels from invoices and packing slips in Amazon PDFs, so you print only the labels.
