Created attachment 867255 [details] error message When I go into `Printer` from `YaST` and then into `Print via Network`, I get this dialog (screenshot attached). As you can see, there is no help text in the dialog. > A firewall may reject printer announcements from CUPS servers > > Regarding firewall setup see the help text of this dialog.
Created attachment 867287 [details] Screenshot: Help text of the main dialog's "print via network" section I guess this refers to the help text in the main dialog; see screenshot. The wording in this pop-up dialog is misleading, agreed.
Help text: "Regarding firewall: Check if a firewall is active for a network zone in which printers are published via network. By default the SuSEfirewall allows any incoming information via a network interface which belongs to the 'internal zone' because this zone is trusted by default. It does not make sense to do printing in a trusted internal network with a network interface which belongs to the untrusted 'external zone' (the latter is the default setting for network interfaces to be safe). In particular do not disable firewall protection for CUPS (i.e. for IPP which uses TCP port 631 and UDP port 631) for the untrusted 'external zone'. To use remote printers in a trusted internal network and be protected by the firewall against unwanted access from any external network (in particular from the Internet), assign the network interface which belongs to the internal network to the internal zone of the firewall. Use the YaST Firewall setup module to do this fundamental setup to gain security plus usefulness in your network and using remote printers in a trusted internal network will work without any further firewall setup. For details see the openSUSE support database article 'CUPS and SANE Firewall settings' at http://en.opensuse.org/SDB:CUPS_and_SANE_Firewall_settings "
