Tilman Hausherr commented on PDFBOX-3046:
-----------------------------------------
I can confirm the effect, which happens only when printing, not when viewing.
My bet was on the type 3 fonts, these are made of PDF content streams. But I
tried with another file (from PDFBOX-2794) and printing was quick. However
there's one difference between your file and the one from PDFBOX-2794: in
yours, the type 3 charprocs have inline image masks, while the ones from
PDFBOX-2794 use vector graphics commands.
> Specific PDF prints really (REALLY) slow

> Key: PDFBOX-3046
> URL: https://issues.apache.org/jira/browse/PDFBOX-3046
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.0
> Environment: Windows 10
> Reporter: Teon Metselaar
> Attachments: mspubcol.pdf, mspubcol.prn
>
>
> On Windows 10 I have printed a test page using the MS Publisher Color Printer
> (which outputs a Postscript-file) and converted that file to PDF using
> GhostScript ps2pdf.
> The resulting single-page PDF file is printed really, really slow (180-190
> seconds) while other documents (even generated using ps2pdf) print a lot
> faster (some seconds).
> I can't figure out why this is. I guess it has someting to do with the used
> font, but other PDF printing libraries (jPedal, jPDFPrint) are able print the
> same documents in a couple of seconds.
