Hej,

I investigated the bug a bit, here are the results:
The PDF we talk about here have '%%Orientation Landscape' or '%%PageOrientation
Landscape' inside, that means CUPS knows that this file is landscape and
therefor rotates it automatically when passing the plain file to lpr.
In part.cpp:setupPrinter() however, the QPrinter orientation property is set to
landscape, because the width of the page is larger than the height. When the
PDF is printed then, the code in core/fileprinter.cpp:optionOrientation checks
whether the QPrinter orientation property is set to 'landscape' and if so
passes '-o landscape' as argument to lpr.
So CUPS will find the %%Orientation tag inside the PDF and rotates the page
correctly, however it will also see the '-o landscape' option on the command
line and rotates the page again -> page is printed incorrectly.

I'm a bit helpless here since I don't know how to fix it in the right way.
Omitting the code in setupPrinter() for the poppler backend and trust that the
orientation is always given inside the PDF?
