Comment 10 for bug 1243484

The problem is caused by the auto rotation done by pdftopdf which makes the pages rotated to print short-edge-first if the printer requires this. If your original page is portrait and you request landscape, pdftopdf rotates it by 90 degrees and after that pdftopdf applies auto rotation and rotates the page by another 90 degrees putting it upside down (180 degrees).

Please try the "nopdfAutoRotate" option:

lp -d queue -o landscape -o nopdfAutoRotate /usr/share/cups/data/default.pdf

Is this what you are looking for?

All PDF files have already defined geometries for each page and the auto-rotation of pdftopdf rotates landscape pages when the printer pulls in the paper only in portrait orientation. So simply sending a PDF file without the "landscape" option does usually the right thing.

The "landscape" option makes more sense if the input data has no ready layout, like plain text. texttopdf will layout the text on landscape-oriented pages with this option.

So why are you using the "landscape" option in your particular case?

So for text files it would make more sense if pdftopdf ignores the "landscape" option as texttopdf is already doing the job. For PDF files you usually decide in the desktop application whether it should be landscape-oriented, so here pdftopdf applying a "landscape" option is also not of much sense.
