John Hewson commented on PDFBOX-2682:
-------------------------------------
Tres, Robin, this is a JDK bug, not a PDFBox bug. It wasn't triggered in 1.8
because we failed to render most PDFs correctly with 1.8. Now that we're doing
rendering properly in 2.0 we're hitting this JDK bug, which is too bad, but
Oracle need to get their act together and fix this two year old bug. In the
meantime we have the ability to rasterize PDFs with PDFBox prior to printing,
which an be done with dpi=0. Emmeran's post above is using out-of-date code and
the equivalent RC3 code now works fine. That's the official PDFBox solution to
this printing problem, as long as you're printing to a physical printer (if
you're wanting to create a PS / XPS or whatever, you're out of luck).
Another less attractive workaround is to use OS X's built in PDF spooling
capability via SimpleDoc, which should just work, though YMMV. On the plus
side, if you're wanting to spool PS / XPS / etc, then this option will work for
you.
Alternatively, we still support JDK 1.6 which doesn't have this bug.
