How to Resize Flipkart Labels & Stretch Barcodes for Thermal Printers

The Challenge with Flipkart A4 Shipping Labels

Flipkart generated invoices are standard A4 documents. The shipping label is situated in the upper portion, containing the routing barcodes, logistics partner info, customer delivery details, and seller details. The lower section includes customer billing information.

For sellers processing hundreds of orders, printing on A4 paper and cutting them manually is a massive bottleneck. Upgrading to a 4x6" thermal label printer saves time and operational costs. However, simple resizing squeezes the barcode, making it too narrow for sorting scanners.

Stretching Barcodes: Preventing Scanning Failures

Our Flipkart Label Tool does not simply scale down the document. Instead, it utilizes high-precision vector calculations:

• It isolates the barcode area (bounding coordinate around y=334.5).
• It extends the drawing matrix width (expanding it to 268pt).
• It keeps the relative height and line spacing intact, meaning the lines remain vector-sharp rather than becoming fuzzy or pixelated.

This is crucial because warehouse scanners rely on contrast and spacing. A stretched barcode is 100% readable, reducing order cancellations due to sorting delays.

Bulk Quantity Matching and SKU cataloging

Often, multiple quantities of the same item are ordered (e.g. washing machine covers, filter candle). In a default print flow, a seller might miss packing multiple items because they only see one label.

Our tool features client-side catalog matching:

1. Load your catalog labels.
2. The client-side parser reads the text data to locate SKU quantities.
3. If a customer ordered 3 units of an item, the tool duplicates the matching product card three times in the output PDF automatically.
4. This prevents dispatching errors and streamlines bulk order sorting.
