Hey there!

I have a problem with PyQt5 and QPrinter which seems to be related to
PyQt 5.11.3 or Qt 5.12. I'm running Manjaro Linux with python 3.7.2,
pyqt5-common 5.11.3, python-pyqt5 5.11.3 and Qt5 at v5.12.0.

I have a program which printed directly to a pdf-file in portrait- or
landscape-orientation using QPrinter. Everything worked perfectly with
PyQt5 v5.11.2 and Qt5 v5.11.
But now, whitout any code-changes, I always get documents in format
"us-letter" in portrait-orientation.

I have a minimal working-example and some pdf-files to illustrate this
here:https://www.dropbox.com/sh/feve6ubvylrko0x/AACC8W0hqEQWSu3t5zGdQI9ra?dl=0

(I had to remove names in two of the documents with LibreOffice Draw.
Thus, the specs say that they are generated by LibreOffice instead of
Qt5.12.)

In my example script, I let python print the printer-settings and they
are correct, but the generated output is wrong.

Can anybody confirm and reproduce this behaviour with my working
example? If this is not related to PyQt5, should I report a bug at Qt5.12?

Thank you!

Regards,

Sam Barkowski
