OneNote gives you the option of saving an entire notebook as a PDF file. Unfortunately I can only seem to find a way for it to do this in portrait orientation, which doesn't make a lot of sense for my content.
It has been suggested during my Googling that I use a PDF printer to work around this, however this isn't a workable solution as OneNote, for some strange reason, will not allow the printing of entire notebooks. I would have to do it section by section which wouldn't take an insignificant amount of time.
Does anyone know a way to force it to output in landscape. An acceptable alternative solution would be a way to change the created PDF file from portrait to landscape, though I don't know how feasible this is.
