 Search for other printer drivers in the NixOS package directory: the official list of packages is [https://search.nixos.org/packages here]. Add the driver to {{nixos:option|services.printing.drivers}}, '''not''' {{nixos:option|environment.systemPackages}}.
-=== Enable autodiscovery of network printers ===
-Most printers manufactured after 2013 support the [https://www.pwg.org/ipp/everywhere.html IPP Everywhere] protocol, i.e. printing without installing drivers. This is notably the case of all WiFi printers marketed as Apple-compatible ([https://support.apple.com/en-ca/HT201311 list]).

-  nssmdns = true;
-  openFirewall = true;
-}
-</syntaxhighlight>
-Discovery is done via the opened UDP port <code>5353</code>. Printers should get automatically detected and visible in your printer configuration client.
-=== Printer sharing ===
-If you want to share a local printer on the network, follow the steps in [[#basic-configuration|Basic Configuration]], but check &#8220;Share This Printer&#8221; when adding it to CUPS. If you have already added the printer to CUPS, reconfigure it to make it a shared printer.</li>

 For debugging purpose, it may be interesting to note that the data folder used by cups (containing the drivers and more) can be obtained by looking in the environment <code>$CUPS_DATADIR</code> (the contents of <code>$out/share/cups/</code> contained in your drivers are linked in this folder).
