Konica Minolta bizhub C1100 prints wrong rotation only in Landscape

[LeGia]

 I have a Konica Minolta bizhub C1100 (black & white) with a persistent printing issue.

Portrait prints correctly

Landscape always prints rotated incorrectly (90° wrong)

Print preview is correct, only the physical output is wrong

This happens on:

Multiple computers

Multiple applications (Adobe Acrobat, Google Chrome)

Both PCL and PostScript drivers

Already tried and ruled out:

Full driver removal and clean reinstall

Testing on different PCs

Changing Auto Rotate, Default Orientation

Portrait is always OK, Landscape is always wrong.

Has anyone with a C1100 experienced this exact behavior?

If yes, what was the real fix in your case?
