That said, the yast printer module gives an error message about firewall, but obviously do not verify it (it should), do not propose to open the firewall (it should) and if I fill the IP as name it find the server so no, the firewall is not the problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

FYI: See "Connection" in http://en.opensuse.org/YaST_Printer ---------------------------------------------------------------------- The YaST printer module does not implement any printer autodetection on its own. It only shows those printer connections which were already autodetected by CUPS (i.e. what the CUPS command line tool "lpinfo -l -v" shows when you run it as root, see http://en.opensuse.org/SDB:CUPS_in_a_Nutshell .. Initially only connections for local printers (i.e. USB printers and parallel port printers) are shown and for HP devices the "hp:/..." connection is preferred. Clicking the "Detect More" button shows all connections which are autodetected by CUPS. .. It depends on the particular printer model whether or not a network printer can be autodetected by CUPS. Usually this works only for those network printers which can be detected in the local network environment via some generic SNMP queries (which works usually for HP and Kyocera printers with an original built-in network interface from the manufacturer). .. If a network printer cannot be autodetected by CUPS or when you like to print via a print server machine (e.g. when printing via a Windows or Samba server or when printing via a traditional Unix server), you have to specify the connection manually via the "Connection Wizard". Unfortunately its name is somehow inappropriate because there are neither "wizards" nor any other kind of obscure "magic" in the YaST printer module, see http://en.opensuse.org/Archive:YaST_Printer_redesign ---------------------------------------------------------------------- Note the "usually" which means: In some cases it does not work. Regarding CUPS network printer detection see http://www.cups.org/documentation.php/doc-1.4/network.html in particular "Troubleshooting SNMP Discovery Problems". In particular regarding SNMP for HP network printers see http://hplipopensource.com/node/216 Regarding "open the necessary port on firewall" see http://en.opensuse.org/SDB:CUPS_and_SANE_Firewall_settings ------------------------------------------------------------------------- Do not open the CUPS IPP port 631 for the external zone in the firewall. .. Assign the network interface which belongs to the internal network to the internal zone of the firewall. ------------------------------------------------------------------------- -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

SNMP might be supported by original HP JetDirect printserver boxes but usually not by other (i.e. non-HP-JetDirect) printserver boxes. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
