Could somebody a non windows system and a printer please run this code
that I created for issue PDFBOX-4011, and report what happens ? The code
should do two things:
- create an image with a barcode-like pattern in the file output.png
- bring a print dialog box and then print the same.
This fails on windows (printed page is blank) but I wonder if this fails
on other OS as well.
