I trying to make a config of my printer, following the description on the wiki.
I have a tar file Fuji_Xerox-DocuPrint_C525_A_AP-1.0-1.i386.tar contaning the driver and I
trying to install it.
It contains:

I have tried to make a Nix file for my printer.
# cat Xerox_Phaser_6125N.nix
{ stdenv }:
stdenv.mkDerivation rec {
name = "Xerox-Phaser-6125N-${version}";
version = "1.0";
src = ./.;
installPhase = ''
# mkdir -p $out/share/cups/model/
# cp myprinter.ppd $out/share/cups/model/
tar -C /tmp/ -xf Fuji_Xerox-DocuPrint_C525_A_AP-1.0-1.i386.tar
cp -r /tmp/usr/. $out/
# If you need to patch the path to files outside the nix store, you can do it this way
# (if the ppd also comes with executables you may need to also patch the executables)
# substituteInPlace $out/share/cups/model/myprinter.ppd \
'';
}
I load it in the configuration.nix like this:
services.printing.drivers = [
(pkgs.callPackage ./Xerox_Phaser_6125N.nix {})
];
Yes, the printer is different then the driver, but it is not an error but a hack. This is a driver
that work for this printer on Linux. 
But when I try to make the system, I get this error:
no Makefile or custom buildPhase, doing nothing

Looks like I make some error in unpacking the tar file.
But what is the proper way to unpack a tar file, and installing something like this?
Try
src = requireFile {
name = "Fuji_Xerox-DocuPrint_C525_A_AP-${version}-1.i386.tar";
url = "https://www.xerox.com"; # this in only printed if src is no in the store
sha256 = "...";
};
dontBuild = true;
add the tarball to the store with nix-store --add-fixed Fuji_Xerox-DocuPrint_C525_A_AP-1.0-1.i386.tar
and in your install phase use
tar -xf $src
mkdir -p $out
cp -r usr $out/.
I get this error!
error: undefined variable 'requireFile'
at /etc/nixos/Xerox_Phaser_6125N.nix:6:9:
5|
6| src = requireFile {
| ^
7| name = "Fuji_Xerox-DocuPrint_C525_A_AP-${version}-1.i386.tar";
You also need to change { stdenv }: to { stdenv, requireFile }: at the beginning of Xerox_Phaser_6125N.nix.
This version can build.
# cat Xerox_Phaser_6125N.nix
{ stdenv, requireFile }:
stdenv.mkDerivation rec {
name = "Xerox-Phaser-6125N-${version}";
version = "1.0";
src = requireFile {
name = "Fuji_Xerox-DocuPrint_C525_A_AP-${version}-1.i386.tar";
# add the file to the store, like this.
# nix-store --add-fixed sha256 ./Fuji_Xerox-DocuPrint_C525_A_AP-1.0-1.i386.tar
url = "https://www.xerox.com"; # this in only printed if src is no in the store
# found sha256 with nix-hash --flat --base32 --type sha256 Fuji_Xerox-DocuPrint_C525_A_AP-1.0-1.i386.tar
sha256 = "14hw5wmmv7xzyz7j2liljlrkprppj68ks7r1lrlyjrrix345pkrf";
};
dontBuild = true;
installPhase = ''
# mkdir -p $out/share/cups/model/
# cp myprinter.ppd $out/share/cups/model/
tar -xf $src
mkdir -p $out
cp -r usr/. $out/
# If you need to patch the path to files outside the nix store, you can do it this way
# (if the ppd also comes with executables you may need to also patch the executables)
# substituteInPlace $out/share/cups/model/FujiXerox/en/FX_DocuPrint_C525_A_AP.ppd --replace "/usr" $out
# substituteInPlace $out/ --replace "/usr" $out
# substituteInPlace $out/ --replace "/usr/" ""
'';
}
But I still need to substitute the path out.
Is is possible to run substituteInPlace recursively on all files in a directory structure?
Where do I lookup information about substituteInPlace and other build in functions?
Is is possible to run substituteInPlace recursively on all files in a directory structure?
find . -type f -print0 | xargs -0 .....
Or
find . -type f -exec ...
Where do I lookup information about substituteInPlace and other build in functions?
I always just check the source (it’s very convenient having ixpkgs checked out). All the various build helpers are in here: https://github.com/NixOS/nixpkgs/tree/master/pkgs/build-support
And substituteInPlace and friends : https://github.com/NixOS/nixpkgs/tree/master/pkgs/build-support/substitute
I am getting this error:

xargs: substituteInPlace: No such file or directory

From this code:
installPhase = ''
# mkdir -p $out/share/cups/model/
# cp myprinter.ppd $out/share/cups/model/
tar -xf $src
mkdir -p $out
cp -r usr/. $out/
# If you need to patch the path to files outside the nix store, you can do it this way
# (if the ppd also comes with executables you may need to also patch the executables)
# substituteInPlace $out/share/cups/model/FujiXerox/en/FX_DocuPrint_C525_A_AP.ppd --replace "/usr" $out
## find files with refs to filters?
grep -lrUH "/usr/lib/cups/filter" $out/ | xargs -I xfile substituteInPlace xfile --replace "/usr/lib/cups/filter" "$out/lib/cups/filter"
## find files with refs to driver (dlut and ppd)
grep -lrUH "/usr/share/cups/" $out/ | xargs -I xfile substituteInPlace xfile --replace "/usr/share/cups/" "$out/share/cups/"
# substituteInPlace $out/ --replace "/usr/" ""
'';
xargs creates subprocesses, substituteInPlace is a shell function; export -f substituteInPlace right before doing grep .. | xargs .. might help (not tested)
export -f … did not work.
maybe try sed -i instead of substituteInPlace
Next problem.

as I understand it “/lib/ld-linux.so.2” need to be exchanged with a /nix/store path. How do I use patchelf to do that?
The current version looks like this.

Next problem an architecture problem? Is this solvable?
I tried to connect to the printer via ftp, but the data-transfer did not work.
I did a port scan to figure out the problem. And discovers that there was a web server
on the printer with status information and more.
completely undocumented in the Printer Settings print out.
Anyone with access to a Mac? That can help me extract the ppd file in this Mac printer diver ?
As described here?
