I have a document in which I use landscape environment but I also have many pages in vertical orientation. I want to do two things:
-change numbering style from 1 2 3 to S1 S2 S3 for all pages
-for pages in landscape mode, change the position of page number so that it is not perpendicular to the text but parallel as on a regular page
\renewcommand{\thepage}{S\arabic{page}}should do for the numbering scheme. The other stuff depends on the documentclass and certain packages – Jan 05 '16 at 14:07articleand I do not know what other packages may be relevant but I use a lot of them. – user2300369 Jan 05 '16 at 14:09fancyhdrpackage, with\pagestyle{fancy},\fancyhead{foo}and\fancyfoot{bar}commands. But there might be other solutions for your problem. – Jérôme Dequeker Jan 05 '16 at 14:15
