>             Project: PDFBox
>          Issue Type: Bug
>    Affects Versions: 2.0.33, 3.0.4 PDFBox
>         Environment: openjdk 11.0.26
> macOS 15.3.1
>            Reporter: Tres Finocchiaro

> When providing a `-dpi` to PDFBOX:
> {quote}Render into intermediate image with specific dpi and then print. Use 
> -1 for automatic detection of printer resolution.
> {quote}
> When printing to a 203 DPI printer on macOS, the quality differences are 
> quite different, with `-dpi 203` being significantly better quality.  This 
> issue was originally discovered in PDFBOX-5967 due to a downstream usage 
> preferring `-dpi 203` for some older JDK versions due to a hard-crash 
> (PDFBOX-2682).
>  
> Good: (with DPI)
> {quote}{{java -jar ~/Downloads/pdfbox-app-2.0.33.jar PrintPDF -dpi 203 
> -noColorOpt ~/Downloads/pb_usps_sample.pdf}}
> {quote}
> Not as good: (without DPI)
> {quote}{{java -jar ~/Downloads/pdfbox-app-2.0.33.jar PrintPDF -noColorOpt 
> ~/Downloads/pb_usps_sample.pdf}}
> {quote}
>  * 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.
