This requires a change in the upstream Qt PDF generation code.

Correct, there is no solution unless changes are made upstream in Qt.

On the Qt issue tracker.

ok thanks - there is already a ticket for QPdfWriter - https://bugreports.qt.io/browse/QTBUG-44451 - however i am not sure, if this is the right class/module!? what component is the "upstream Qt PDF" part of?

It is correct. You might want to watch the issue in Qt to get notified when it gets fixed.

In case anyone else wants meta data support without having to wait for any upstream fixes: I wrote this little script. Yes, it's messy but it works at least for me (OS X 10.11.6, on Linux you'd maybe need to install php (or rewrite that part)). 😄
It uses wkhtmltopdf to do the conversion to pdf, then exiftool to add the meta data, then qpdf to relinearize and write protect the file.

I'm afraid I can't. But the programs I mentioned also run on windows, so you should at least be able to do each of these steps, manually.

No, it does not.

You could try to use a tool like curl to download the file, first. Or use a headless browser like phantomjs to get the meta data.

owww thanks chris i think wktopdf same with mpdf can create metadata but great tools wktopd:D

[IMP] *: automatically brand PDFs (from PyPDF2) as Odoo
2d16323 
To avoid having to fixup half a dozen places where we're creating PDF
writers, and possibly ending up with new ill-configured writers in
the future, patch PyPDF2's own writer with a subclass setting /Creator
and /Producer.

Note that this will not affect non-post-processed PDFs generated by
wkhtmltopdf. wkhtmltopdf does not allow setting these properties[0][1], so
to fix this issue we'd have to alter _run_wkhtmltopdf to pass the
result through PyPDF2 in order to alter its metadata.
