If the document size is not in 4*6 inches, or there is a large blank area around the shipping label(may on the right or left), or the label prompts "cut on dotted line"(please refer to the picture).we need to cut off the blank area to print correctly.
- Use the MunbynPrinter program to crop
MunbynPrinter program does not support all 8×11 inch label PDF files. Currently, it only supports processing 8×11 inch label PDF files from UPS official website / USPS official website / DHL / FedEx / Canada Post / Collissimo La Poste.
