Hi Samuel
I am warming up this rather old thread, since I finally got around to
experiment a bit.

There is software for Windows, not part of the standard embosser driver, which
can print SVG and black/white, 50 DPI pictures, so I was wondering whether
somebody did something similar on Debian?
Yes, I did :)
See the Braille Embossing section of /usr/share/doc/cups-filters/README.gz
Thanks for implementing this :-). Where is the upstream source of this file?
I found the set up to be astonishingly simple, not remotely comparable with
the set up on Windows that I needed to do :-(.

How good is the interpretation of the layout?
It's simply liblouis.
Ok, so I'll need to take a look there. The first results with the embosser
looked strange, a mixture of English and German grade 2 braille...
How would I adjust settings such as the language to emboss?
As usual with cups, in the http://localhost:631 web interface, or on the
fly on the command line.
I had the impression that it simply ignored settings that I have set in the
printer tab of my text editor (pluma), but I need a more reliable way to test
this. When I print from pluma, it always inserts the path to the file at the
top of the printed result, any clue why?
After a while, printing stopped working. I investigated the print command that
cups showed:
ile2brl -p -Chyphenate=yes -CliteraryTextTable=en-us-brf.dis,en-GB-g2.ctb,de-g2.ctb,de-de-comp8.ctb,braille-patterns.cti -CinputTextEncoding=UTF8 -CbraillePages=yes -CbraillePageNumberAt=bottom -CpageNumberBottomSeparateLine=yes -CprintPages=no -CpageSeparator=no -CpageSeparatorNumber=yes -CcontinuePages=no -CcellsPerLine=27 -ClinesPerPage=26 | | addmargins
First I figured out that liblouisxml-data was missing, should this be added as
a dependency?
Second, there seems to be no addmargins in the Debian archive, is this an
oversight?
Last but not least, there's a double pipe, I suppose dash doesn't like this.
When I pipe "hi" into the above text (with addmargins removed) I get an error
like pasted below this e-mail. Any idea what is going wrong?
I'd need to try it out myself. I'd think that curves are much more precise
with ~50 DPI,
Yes, but I'm unsure one can feel the difference that much.
I have tried to plot a diagram that has two close lines and it shows as one
line in the printed version. It is better when using Gnuplot with its ASCII
output module. I am not sure whether the issue is the missing resolution or
the conversion beforehand.
Thanks
Sebastian
