If I use the wait mode and print two documents, one in portrait, one in landscape, then use the combine button and print, then the combined document is all portrait with the landscape pages rotated.
If I print these separately the landscape appears as landscape which is what I want for on-screen viewing.
I have tried all combinations of the auto-rotate setting - None, All, Single page. Rotate all gives me the landscape output for the single file but not the combined file.
This has not yet been fixed. I'm using version 1.4.2, and still the same problem when combining documents.
The option "Auto -Rotate all" may work for pages that have only horizontal text lining (detecting algorithm). As soon as there are graphs or other lines, this won't work.
The option "Auto-Rotate - None" takes the orientation of the first document and applies it to all the rest when combining. For me, the bug in in there. This function should consider and apply the original orientation of every document that is combined.
