Flipkart label not printing — causes and fixes

1. Nothing prints at all

Check the USB or network connection first, then confirm 4×6 / 100×150 mm paper is selected in the driver — not A4 or Letter. Also confirm the roll is loaded thermal-coated-side facing the print head, and that the printer is not paused or set offline in your OS print queue.

2. Label prints but blank or faded

Increase darkness one notch in the driver. A very common new-printer mistake is loading the roll backwards — thermal paper only darkens on the coated side, so a reversed roll prints nothing however high the darkness is set. Avoid jumping straight to maximum heat on thin stock; it can smear rather than darken.

3. Barcode does not scan at the hub

Usually the full A4 packing PDF was sent to a 4×6 printer with Fit to page, shrinking the barcode below scannable resolution — or a manual crop was too tight against the bars. Fix: crop with the Flipkart shipping label cropper first, which keeps a safety margin around the barcode automatically, then print at 100% / Actual Size and never Fit to page.

4. Half the sticker is invoice text

The original PDF mixed the shipping label with invoice content on one A4 page. See Flipkart A4 to thermal label — cropping removes the invoice block and prints only the label region.

5. Label prints the wrong size or stretched

The driver’s paper size does not match the PDF’s actual page size. A cropped label from this tool is a genuine 100 × 150 mm page, but if the driver is set to “Auto” or a different size, the printer scales it anyway — sometimes unevenly in each direction, which is what stretching looks like. Set the driver paper size to match exactly; see thermal printer settings.
