Hi Pablo,
The problem is that the filius-page is higher than the width of an A4. 
So there is no way other than to scale the original pages down to a 
height of 210mm. For this action you can use something like
Thanks for your fast reply. I thought it was possible to set center the

The following code in a tex-file.
\definepapersize[Mypaper][height=210mm,width=123mm]
\setuppapersize
  [Mypaper][Mypaper]
\setuplayout
  [page]
\starttext
\copypages
  [input.pdf]
  [scale=905,
   offset=0pt]
\stoptext
The resulting pdf-file should then be arranged. However I would  suggest 
not to use 2UP.  Arranging the whole file (351 pages) with 2UP results 
in a rather thick single booklet of 88 A4-sheets. What you can try is to 
setup arranging as follows (untested). Put this code into an environment 
file e.g. arrange.tex
Thanks for the code bellow, but I'm not trying to make a booklet, but to 
print the book to cut the paper in two pieces to bound it.

Thanks anyway,

Pablo

On the commandline call conTeXt as follows
texmfstart texexec --pdfarrange --environments=arrange 
--result=output.pdf  input-scaled.pdf
I hope this helps

Hi there,
I would like to use the imposition capabilities from ConTeXt to be able
to print a PDF book in a standard laser printer. To save paper, I use 
the 2UP arranging option thanks to this code from the wiki:
\definepapersize    [filius][width=135.9mm, height=231.8mm]
\setuppapersize        [filius][A4,landscape]
\setuparranging        [2UP,doublesided]
\setuplayout [backspace=0pt,
    topspace=0pt,
       width=middle,
      height=middle,
    location=middle,
      header=0pt,
      footer=0pt,
      grid=no, marking=off]
\starttext
\filterpages[ZittrainTheFutureoftheInternet.pdf][4:351][height=21cm]
\stoptext
The PDF file can be downloaded from
http://futureoftheinternet.org/static/ZittrainTheFutureoftheInternet.pdf.
The issue here is that I get a resulting paper size with the filius 
height and not with 21cm from A4.
I have tried have the output in a standard A4 paper size, but all that 
I got is a scaled down PDF. I would like to avoid scaling the document 
if that were possible.
Is there any way, given the example above, to impose the filius paper 
size on a real landscape A4 without having to scale down the PDF 
document?
Thanks for your help,
Pablo
