CUPS on Managed node for windows clients

Hello everyone,

I have UCS as a slave (replica) node with a CUPS print server installed on it. Everything seems to be working fine. From a Windows client, I can connect to \UCS-SDC1 and see the installed printers, and I can add it to Windows printer management.

Now I tried to install UCS as a Managed Node in another VLAN, joining the domain is OK, I installed the CUPS print server on it. But I can’t connect to it from the Windows client.

The following works:
ping ucs-c-cups
in the browser http://ucs-c-cups (Univention web management is displayed)

But the following does not work:
\ucs-c-cups in File Explorer – it cannot connect
add ucs-c-cups to printer management – after a while, a red arrow appears

CUPS is definitely functional; in the Linux client, I just need to add “ServerName ucs-c-cups” to /etc/cups/client.conf and I can print without any problems.

Is the “Managed node” role with the CUPS print server installed capable of providing printing services for Windows clients? Do I need to install any additional packages (samba)?

Thanks.
