Comment 31 for bug 166678

~suv:
"When I open a drawing saved with the document property 'Page orientation' set to 'Landscape', the print dialog tab 'Page Setup' still shows 'Portrait'. After closing the print dialog, changing the document property 'Page orientation' to 'Portrait' and back to 'Landscape' and reopening the print dialog, the print settings now correctly reflect the document setting of the page orientation 'Landscape' and prints the document correctly."

Confirmed.
Since the bug is partially fixed, I've reopened this report "in progress".
