Why doesn't my label print correctly (Use 8*11 inches file for printing)?

Because your file is not a 4*6 label file (it looks like an 8*11 one), resulting in a lot of white space around the label.

If the document has a large blank area or other information besides the label, we need to cut off the blank area by cropping tools or software.

Solutions:

1. Crop white space with Adobe Acrobat Reader
   

   This video is about how to operate it: youtu.be/ucBS9epBnnU

   The Adobe Acrobat Reader free download link (it's a free version, not Pro DC)

2. Use the Munbyn Label Converter to crop
   

   But the 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.
