/* usage: (sorry, its still impure but works!)

impure directory:
mkdir /opt/gutenprint; sudo cp -r $(nix-build -A gutenprintBin -f $NIXPGS_ALL) /opt/gutenprint

add the following lines to bindirCmds property of  printing/cupsd.nix:

  ln -s ${pkgs.gutenprintBin}/lib/cups/backend/* $out/lib/cups/backend/
  ln -s ${pkgs.gutenprintBin}/lib/cups/filter/* $out/lib/cups/filter/
  mkdir -p $out/lib/cups/model
  cat ${pkgs.gutenprintBin}/ppds/Canon/Canon-PIXMA_iP4000-gutenprint.5.0.sim-en.ppd.gz |gunzip > $out/lib/cups/model/Canon-PIXMA_iP4000-gutenprint.5.0.sim-en.ppd
  sed -i 's@/opt/gutenprint/cups@${pkgs.gutenprintBin}/cups@' $out/lib/cups/model/Canon-PIXMA_iP4000-gutenprint.5.0.sim-en.ppd

Then rebuild your system and add your printer using the the localhost:603 cups web interface
select the extracted .ppd file which can be found in the model directory of
sed -n 's/^ServerBin //p' $(sed -n 's/respawn.*-c \(.*''\) -F.*''/\1/p' /etc/event.d/cupsd)
(sorry, cups still doesn't see it. You could copy it into /nix/store/
*-cups/lib/cups/model/ and you would be able to select canon -> PIXMA 4000
then. I've tried that.

TODO tidy this all up. Find source instead of binary. Fix paths ... Find out how to check ink levels etc
