Hi Hanno,

    $ dvi2fax foo.dvi 
    Unknown device: dfaxhigh

I believe this error message is coming from gs, rather than dvips.
That is, your gs has been compiled without the dfaxhigh device.
gs --help will list available devices.

A dvips error would look more like this:
  dvips: warning: no config file for ...
but as far as I can see, the "dfaxhigh" dvips "printer" file
(config.dfaxhigh) is still present and available.
dvi2fax does work for me.

    It seems to me that this is just a frontend for dvips 

A frontend for dvips ... | gs ...

If you run each command separately, you can see for sure.

Happy faxing,

P.S. Incidentally, looking at the script, I note that -lo only affects
the ghostscript device, not the dvips pseudo-printer, which remains as
dfaxhigh. That may have been an oversight on te's part, but then again,
it may not have been, as gs will probably do fine downsampling the
PostScript, and there might be Metafont errors at that low of a
resolution. So I'm inclined not to change it, for that among other reasons.
