A4 to 4×6 PDF Conversion Guide for Thermal Printing
Why convert A4 shipping labels to 4x6 thermal?
Most Indian e-commerce marketplaces (including Amazon, Flipkart, and Meesho) default to generating shipping labels in standard A4 PDF document sizes. If you try to print these directly on a thermal printer, the shipping slip scales down automatically, making the barcode blurry, distorted, and unreadable for courier hub scanners. Converting A4 shipping labels to 4x6 layout dimensions is the absolute best way to ensure package tracking scans first time, every time, saving you from courier rejection penalties and lost shipments.

Configuring printer settings for borderless 4x6 label rolls
To print cropped labels successfully on thermal printers (like TSC, Gprinter, Xprinter, or TVS):
- Access the printer properties on your computer.
- Set the paper size to 100mm x 150mm (4x6 in) portrait.
- Configure Print Scale to 100% or "Actual Size". Never use "Fit to page" or "Shrink oversized pages" settings, which distort the barcode lanes.
- Increase print darkness only until barcode lines are solid and distinct; excessive darkness can make adjacent bars bleed together.
