Many thanks for your reply, Wolfgang.

I’m afraid I must be missing something. If I remove the first line from
the sample above, I don’t get the third page.

I’d say this is redundant. "portrait" is duplex printing flipping the
long side.

The issue comes from having one key for five values and also from mixing
viewing options with printer options (the PDF spec shelters them in the
viewer preferences dictionary).

In this case, doublesided sets layout "TwoColumnRight" (which is a
display setup) disabling also duplex and fixed printing (which are
printing setups).

As I proposed before (but Hans is busy with other issues), there should
be four different keys in \setupinteraction (when not moving them to a
new \setupprinting command):

duplex  page portrait landscape

fixed   (no value is required)

copies  number

pdfpapersizeyes no

I’d love to contribute the patch myself, but Lua is totally unknown to
me. I have tried to adapt lpdf-mis.lua, but this is beyond my knowledge.

So I will have to wait until the new keys are implemented :-(.

Many thanks for your help,


Pablo

Wolfgang, this was my original sample:

\setuppagenumbering[alternative=doublesided]
\setupinteractionscreen[option=portrait]
\starttext
No duplex printing.
\page[right]
In this document.
\stoptext

The doublesided alternative disables duplex printing.

Hans wrote about portrait and landscape as directives. I guess they
should be invoked with \enabledirective, but I don’t know how.
No, the option key for \setupinteractionscreen is correct but there are 
a few problems.


1. When you have a doublesided document the “portrait” option loads the 
values

   of the doublesided option.

2. Since you can set only one argument for the option key context has to 
set a values
   for the PDF document which means you can set the zoom value and 
dupley print
   option at the same time. A better solution would be to assign each 
option only a certain
   function and allow one to set 
\setupinteractionscreen[option={doublesided,portrait}].

Wolfgang, this was my original sample:

\setuppagenumbering[alternative=doublesided]
\setupinteractionscreen[option=portrait]
\starttext
No duplex printing.
\page[right]
In this document.
\stoptext

The doublesided alternative disables duplex printing.

Hans wrote about portrait and landscape as directives. I guess they
should be invoked with \enabledirective, but I don’t know how.

Many thanks for your help,

How should I invoke them? (Sorry, but I cannot grep it. This is too
complex for me.)


\setupinteractionscreen[option=landscape] % option=portrait

I’m afraid that doublesided alternative disables duplex printing.


sure, that's why we have 'portrait' and 'landscape' as directives


This would be a good reason to implement the features already asked at
https://mailman.ntg.nl/pipermail/ntg-context/2016/084298.html.

Many thanks for your help,
