    No, that is not correct. In any case I was referring to the Avahi hostname (no DNS required).

    I referred to home routers, typically provided by Internet Service Providers: https://stevessmarthomeguide.com/home-router-setup/

    A residential gateway usually provides
    • configuration via a web interface
    • routing between the home network and the Internet,
    • connectivity within the home network like a network switch, hub, or WLAN base station,
    • network address translation (NAT)
    • DHCP for IPv4 and IPv6, and
    • firewall functions

    See https://en.wikipedia.org/wiki/Residential_gateway

    In any case I was referring to the Avahi hostname (no DNS required).

    I see. Avahi being active can result in multiple entries confusing less experienced users and complicating the installation.
    Code:
    erlangen:~ # systemctl list-unit-files avahi*
    UNIT FILE STATE VENDOR PRESET
    
    0 unit files listed.
    erlangen:~ # systemctl list-units avahi*
      UNIT LOAD ACTIVE SUB DESCRIPTION
    0 loaded units listed. Pass --all to see loaded but inactive units, too.
    To show all installed unit files use 'systemctl list-unit-files'.

    To my experience the following procedure works reliably for wireless printers:

    1. connect the printer to the network following the user instructions of the manufacturer, usually using Wi-Fi Protected Setup and Push Button Configuration

    2. install printer driver, e.g.
    Code:
    erlangen:~ # zypper in https://download.brother.com/welcome/dlf103565/hll2350dwpdrv-4.0.0-1.i386.rpm
    Loading repository data...

    3. The printer queue created by post install script won't work, since printer is not attached to USB. Fix using 'yast2 printer' > Printer Configurations > Edit > Detect More > OK.

    It's not true to say that all do. I owned one that did, and several others that do not.

    Sorry, that is more nonsense. In any case, the CUPS dnssd backednd (which many use for automatic discovery) has been in use for years.

    I will close this thread, as you appear to be adding unnecessary comments to an already solved thread.
