------------------------------------------
Slight update, with some help from the PDFBOX team, we can fix the
transparency-related quality issues by removing the transparent layers.
Working class is here:

> more details if needed):
> * Created with Adobe Illustrator
> * Form-filled programmatically using using FPDI

> {noformat}
> java -jar /Users/owner/Downloads/pdfbox-app-2.0.8.jar PrintPDF -silentPrint
> -defaultPrinter PDFCreator -dpi 0 ~/Downloads/test.pdf{noformat}
> Also reproduced on CUPS-PDF, Microsoft Print To PDF
> The symptom from the business area was "slow printing", but this symptom was
> a side effect of a high resolution rasterization, causing the PDF to spool to
> about 800MB.
