Comment 8 for bug 166678

On a I can confirm this problem using Inkscape 0.46_0 (Ubuntu gutsy repositories; Brother 5250-DL laserprinter (CUPS)).
A landscape-set document prints in portrait mode. I am not able to change to "portrait/landscape" in the printer dialog menu (option is greyed out).

A .pdf file of this document will print in portrait mode when opened with Adobe-PDF-viewer (properties indicate "portrait"). When this same .pdf-document is opened in Evince, it prints landscape (properties indicate "landscape").
A .ps-file of this document (printing from Evince) -> prints in landscape, but a .ps-file "generated with Cairo" prints portrait.
Inconsistent?
This can be a printer-settings issue, but I observed this only now with Inkscape documents just after installing 0.46 (but, frankly, I do not work often on landscape-sized paper and might have missed this issue). [and, it is a minor issue to me]
