Bug: Mixed orientation documents result in wrong output on MacOS
A PDF document containing portrait and landscape pages is printed incorrectly on MacOS (tested on Mojave (10.14) and Catalina (10.15)).
I attached a test document (A4B5MixedOrientation.pdf) containing 2 pages A4 portrait followed by 2 pages B5 landscape.
Because of the different page sizes in the document it is necessary to switch on "Choose paper source by PDF page size" in the Acrobat print dialog.
When printing this document the output is wrong for the 2nd page. I attached the PS output and a distilled PDF version of the output (GenericPS_2020_08_28_091748.ps and GenericPS_2020_08_28_091748.pdf).
For isolating the problem I used the PPD-only built-in Generic PostScript Printer driver of MacOS but the problem also occurs with my regular PS printer which uses a different driver.
I am using Acrobat Reader DC (2020.012.20043). This issue does not occur in Adobe Reader XI (11.0.23).
Unfortunately I was unable to attach the PostScript output as .ps file. As a workaround I uploaded it as .ps.log file (with identical content).
