A label provided to us as a PDF is failing to print properly when printed by a java program using pdfbox 2.0.4 - I upgraded to 2.0.8 same issue - I have also tried using the command line utility to test to check that it wasn;t something that I had coded incorrectly..
The attached image with missing barcode is from the output of java -jar pdfbox-app-2.0.8.jar PrintPDF c:\tmp\PARCELFORCE_FTN0000892136.PDF.
The image with the barcode OK is from acrobat reader. The PDF is as sent to us.
The original PDF is also attached/
Any suggestions / fixes quite welcome
