So the contention is that "printing in landscape" involves selecting the Landscape option in a drop-down menu of evince and then that will produce a 90 degree rotation of a PDF page. However, I observe (on unstable, jessie and stretch) that a page like this +----------+ | | | | +----------+ is not rotated. Auto Rotate and Center was unchecked and the technique in https://lists.debian.org/debian-user/2017/12/msg00584.html was used to examine the PDF to be sent to CUPS. It appears that "printing in landscape" doesn't always lead to a 90 degree rotation when using evince.. -- Brian.
