You'd need to adjust this somewhat 0) adjust image directory 1) adjust scale /
position so that it appears on your tiny label (I tested with an A4 page) 2)
play with the rendering hints if the effect doesn't occur (or use the rendering
hints in your application). 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.
