==Installing scanner support==

Scanner support is provided by the SANE library. To enable scanner support, amend ~~<tt>~~/etc/nixos/configuration.nix<~~/tt>:~~

Scanner support is provided by the [http://www.sane-project.org SANE] library. To enable scanner support, amend your system configuration like so:

{{file|/etc/nixos/configuration.nix|nix|<nowiki>

~~<syntaxhighlight lang="nix"~~>

{

...

hardware.sane.enable = true;

hardware.sane.enable = true; # enables support for SANE scanners

...

}

</~~syntaxhighlight~~>

</nowiki>}}

Users in the <code>scanner</code> group will gain access to the scanner, or the <code>lp</code> group if it’s also a printer. To add yourself to these groups, amend your system configuration as follows:

~~It is also very likely that users will required to be~~ in the ~~following groups~~ <tt>scanner</tt> ~~and~~ <tt>lp</tt>, ~~so you can for example configure it~~ as ~~follow on NixOs (don't forget to login/logout after rebuilding NixOs)~~:

{{file|/etc/nixos/configuration.nix|nix|<nowiki>

<~~syntaxhighlight lang="nix"~~>

{

...

users.users.YOURUSERNAME.extraGroups = [ "scanner" "lp" ];

...

}

</~~syntaxhighlight~~>

</nowiki>}}

{{Tip|The detection of installed backends by SANE depends on the <tt>LD_LIBRARY_PATH</tt> environment variable, which is set at login. You will need to '''logout''' and '''login''' again for backend changes to take effect after ~~<tt>nixos-rebuild switch</tt>~~.}}
