Dear list,

the way to have a booklet is straightforward:

\setuppapersize[A4][A3, landscape] \setuparranging[2UP] \setupbodyfont[128pt] \setupmakeup[page] [pagestate=start, align=center, style=\ssbfd] \starttext \dorecurse{24} {\startmakeup[page]\recurselevel\stopmakeup} \stoptext

But what happens if I already have landscape A3 that I need to print as an A4 booklet?

I mean, which is the way to instruct ConTeXt to cut each A3 page in half and arrange each half in its proper position in the booklet?

Taking A3 pages and reducing them to A5 so they can be printed as a booklet of A4 sheets is simple enough. But I don't understand what you mean by "cut each A3 page in half"? Is the A3 already in the form of two A4 sheets per page so that there is a gutter between them and you effectively want to extract each A4 half page, arrange in order, and then print reduced to A5 in a booklet of A4 sheets? — Bruce Horrocks Hampshire, UK
