double-sidedkoma-script
I write a document that is to be printed 2-on-1 (on A4 paper) so double-sided layouts seem reasonable, e.g. for margins. Therefore, I use scrartcl with twoside.
My problem is that this assumes that odd pages are on the right and even on the left. This is reasonable when printing leaflets (i.e. first page is cover) but that is not the case for me.
Therefore, I want to flip everything. Is there an easy way to do this?
Odd numbered pages should always be right pages!
So you should always use \cleardoublepage before changing page numbering, because it makes no sense to change page numbering on the left side of a double sided print:
\documentclass[twoside]{article}% It's better to tell already the class to use twoside!
\usepackage[showframe]{geometry}
\begin{document}
This is the first page; it should be a right page (recto).
\cleardoublepage
\pagenumbering{arabic}
This is the third page; it should be a right page, because changing page numbering should always be done on right pages!
\end{document}
If you simply wanted to suppress page number at the first page of an article, try:
\documentclass[twoside]{article}% It's better to tell already the class to use twoside!
\usepackage[showframe]{geometry}
\begin{document}
\title{Title}
\author{Me}
\maketitle\thispagestyle{empty}
\begin{abstract}A short abstract of the document.\end{abstract}
Some more text, e.g. a table of contents.
\clearpage
This is the second page; it should be a left page and numbered 2!
\end{document}
Note: You may use \cleardoublepage before \pagenumbering even at oneside documents, because in this case it would have the same result \clearpage would have.
But, if you really, really must have odd pages left and even pages right, you may simply switch the margins (and the margin used for \marginpar):
\documentclass[twoside]{article}% It's better to tell already the class to use twoside!
\usepackage[showframe]{geometry}
\makeatletter
\newcommand*{\flipmargins}{%
\clearpage
\setlength{\@tempdima}{\oddsidemargin}%
\setlength{\oddsidemargin}{\evensidemargin}%
\setlength{\evensidemargin}{\@tempdima}%
\if@reversemargin
\normalmarginpar
\else
\reversemarginpar
\fi
}
\makeatother
\begin{document}
This is the first page; it should be a right page (recto).
\flipmargins
\pagenumbering{roman}
This is the second page; it should be a left page (verso).
\end{document}
Using a page style like headings you may also need to change the page style, e.g., to print the numbers near the outer margin. You may do this, using either scrpage2 or fancyhrd. Here an example using scrpage2:
\documentclass[twoside]{article}% It's better to tell already the class to use twoside!
\usepackage[showframe]{geometry}
\usepackage[automark]{scrpage2}
\pagestyle{scrheadings}
\makeatletter
\newcommand*{\flipmargins}{%
\clearpage
\setlength{\@tempdima}{\oddsidemargin}%
\setlength{\oddsidemargin}{\evensidemargin}%
\setlength{\evensidemargin}{\@tempdima}%
\if@reversemargin
\normalmarginpar
\else
\reversemarginpar
\fi
\ifdim \evensidemargin>\oddsidemargin
\ihead{\headmark}%
\ohead[\pagemark]{\pagemark}%
\else
\ihead[\pagemark]{\pagemark}%
\ohead{\headmark}%
\fi
}
\makeatother
\begin{document}
\section{Normal pages}
This is the first page; it should be a right page (recto).
\flipmargins
\pagenumbering{roman}
\section{Inverse margin pages}
This is the second page; it should be a left page (verso).
\end{document}
Alternative:
One completely different alternative would be to fake the page number, given by \thepage:
\documentclass[twoside]{article}% It's better to tell already the class to use twoside!
\usepackage[showframe]{geometry}
\makeatletter
\newcommand{\@arabicplusone}[1]{\@arabic{\numexpr #1+1\relax}}
\newcommand{\@romanplusone}[1]{\@roman{\numexpr #1+1\relax}}
\newcommand{\@Romanplusone}[1]{\@Roman{\numexpr #1+1\relax}}
\newcommand{\@alphplusone}[1]{\@alph{\numexpr #1+1\relax}}
\newcommand{\@Alphplusone}[1]{\@Alph{\numexpr #1+1\relax}}
\makeatother
\newcommand*{\pagenumberingplusone}[1]{%
\pagenumbering{#1plusone}\setcounter{page}{0}%
}
\begin{document}
This is the first page; it should be a right page (recto). See
page~\pageref{test}.
\clearpage\pagenumberingplusone{roman}
This\label{test} is the second page; it should be a left page (verso).
\end{document}
Disadvantage of this suggestion would be, that if a package uses page counter directly for something else but testing odd or even the result may be unexpected. The advantage of this suggestion would be, that pages with odd value of counter page shows not only an even page number but will be handled to be a even=left page by LaTeX and every class or package that uses \c@page or \value{page} for the test (and vica versa).
For example, the page can be shifted by moving the output box right before the page is shipped out:
\documentclass{book}
\usepackage{lipsum}
\usepackage{fancyhdr}
\pagestyle{fancy}
\usepackage[a4paper]{geometry}
\usepackage{atbegshi}
\AtBeginShipout{%
\ifodd\value{page}%
\edef\mytemp{%
\ht\AtBeginShipoutBox=\the\ht\AtBeginShipoutBox\relax
\dp\AtBeginShipoutBox=\the\dp\AtBeginShipoutBox\relax
}%
\sbox\AtBeginShipoutBox{%
\raisebox{-1in}{\usebox\AtBeginShipoutBox}%
}%
\mytemp
\fi
}
\begin{document}
\lipsum
\end{document}
In case of pdfTeX in PDF mode, alternatively \pdfvorigin could be changed inside \AtBeginShipout.

Let's suppose that your document is like this one, with also headings and footers:
with this output:
To flip the margins, you can do:
To also flip the margin pars, the following line is required
To flip headers and footers, it is necessary to build a new style that flips everything and then use this style:
The following MWE
should give you exactly what you want:
