        Epson Inkjet Printer Driver (ESC/P-R) for Linux and the
	corresponding PPD files. The list of supported printers
	can be found at http://www.openprinting.org/driver/epson-escpr/ .

	To use the driver adjust your configuration.nix file:
	  services.printing = {
	    enable = true;
	    drivers = [ pkgs.epson-escpr ];
	  };

  To setup a wireless printer, enable Avahi which provides
  printer's hostname to CUPS and nss-mdns to make this
  hostname resolvable:
    services.avahi = {
      enable = true;
      nssmdns = true;
    };'';
