You'd need to adjust this somewhat 1) adjust scale / position so that it
appears on your tiny label 2) play with the rendering hints if the effect
doesn't occur. Btw our print utility has an option for barcodes
("-noColorOpt"), maybe try that one if you didn't already.

> Printed barcodes are fuzzy on macOS only
> ----------------------------------------
>
> Key: PDFBOX-5967
> URL: https://issues.apache.org/jira/browse/PDFBOX-5967
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.33, 3.0.4 PDFBox
> Environment: macOS 15.3.1 (Intel and Apple Silicon)
> openjdk 11.0.25, openjdk 23.0.1
> Reporter: Tres Finocchiaro
> Priority: Major
> Labels: macOS, print
> Attachments: PDFBOX-5967-reduced1.pdf, PDFBOX-5967-reduced1.png,
> pb_usps_sample.pdf, print_comparison.png
>
>
> The attached PDF prints well on Windows and Linux, but on macOS the barcodes
> are fuzzy and unscannable. We print a lot of 4x6 labels using pdfbox and
> CUPS, so I'm not sure what is different about this label. It's created by
> Pitney Bowes through their shipping API.
> * I understand that this may be a result of something happening at the
> OS-level. If this is the case, any guidance as to how to isolate and provide
> a bug report for openjdk is greatly appreciated.
> * If there's a workaround that can be used as a stop-gap leveraging the
> PDFBOX API, that would also be greatly appreciated.
> *Steps to reproduce:*
>
> * *PDFBOX 3.0*
> {{java -jar ~/Downloads/pdfbox-app-2.0.33.jar PrintPDF
> ~/Downloads/pb_usps_sample.pdf -mediaSize=4x6}}
> * *PDFBOX 2.0*
> {{java -jar ~/Downloads/pdfbox-app-2.0.33.jar PrintPDF
> ~/Downloads/pb_usps_sample.pdf}}
> Tests were performed on physical hardware (Zebra ZD620 using the CUPS ZPL
> driver) with openjdk 11.0.25 and openjdk 23.0.1.
