    Question Re: firefox print dialog show all network printers

    What is CUPS indicating with respect to known printer queues?

    Are all the indicated printers really available on your LAN? Or, is there an issue with the Firewall of your IP/DSL Router?

    This is down to cups-browsed AFAIU, which uses Avahi to discover network printer broadcasts.

    In /etc/cups/cups-browsed.conf there is
    Code:
     Which protocols will we use to discover printers on the network?
    # Can use DNSSD and/or CUPS and/or LDAP, or 'none' for neither.
    
    BrowseRemoteProtocols DNSSD
    If desired, change it to
    Code:
    BrowseRemoteProtocols none
    then restart cups-browsed.

    now here it is set to
    Code:
    BrowseRemoteProtocols DNSSD,CUPS
    I can try tomorrow, ...but I have three remote printers installed, if I set it to none, does cups allow me to print with these installed printers??

    When you configured them in CUPS, I assume it will be possible to user them as always.

    And about the fact that CUPS now find them which wasn't the case earlier, you should of course try to remember what changed on the system in that time frame. We can only help with that if we have an idea what changed in the system, or maybe in the printers (are you the printer and/or network manager?).

    As long as they are configured in /etc/cups/printers.conf then they should work as always (as Henk already mentioned).

    yes, but I didn't installed/configured all these printers, and I used the yast>configure printer to install the three printers I use (I suppose it use CUPS)

    I'm only a user, I'm not printer and/or network manager, and from when CUPS didn't find printers on the LAN and now I didn't changed anything in my leap 42.3, I only updated...

    I modified /etc/cups/cups-browsed.conf as follow:
    Code:
    # Which protocols will we use to discover printers on the network?
    # Can use DNSSD and/or CUPS and/or LDAP, or 'none' for neither.
    
    # BrowseRemoteProtocols DNSSD,CUPS #2017-10-20ott this was the original
    # 2017-10-20ott the one belw here modified by me
    BrowseRemoteProtocols none
