I was trying ConTeXt out and found out about imposition. I'm specifically interested in the 2UP schema, so I can just print on a regular A4 and trim.
I have a book typeset using LaTeX and memoir. Then I took a look at memman.pdf, to try to find information about how this could be accomplished. I tried using a4paper and landscape class option, then \pageav, but that just got me a A4 sheet with a A5 page inside it.
How can it be done? I read something about pdfpages but didn't try it just yet, because I think there is a native way of doing so using memoir.
