There is a line: BrowsePort 631 but "Port" is not specified, AFAIKT. Anyway, I've pasted cupsd.conf below; thanks for replying. John # CUPS configuration file, generated by CUPS configuration tool. # This tool is part of KDEPrint, the printing framework for KDE # since version 2.2.2 and is used by the CUPS supporting module # in KDEPrint. The predecessors to KDEPrint in former KDE releases # were KUPS and QtCUPS; they are deprecated and no longer maintained. # # Author: Michael Goffioul # # Web site: http://printing.kde.org/ # ######################################################################## # # # This is the CUPS configuration file. If you are familiar with # # Apache or any of the other popular web servers, we've followed the # # same format. Any configuration variable used here has the same # # semantics as the corresponding variable in Apache. If we need # # different functionality then a different name is used to avoid # # confusion... # # # ######################################################################## # # Server # Server name (ServerName) # # The hostname of your server, as advertised to the world. # By default CUPS will use the hostname of the system. # # To set the default server used by clients, see the client.conf file. # # ex: myhost.domain.com # #ServerName myhost.domain.com # Server administrator (ServerAdmin) # # The email address to send all complaints or problems to. # By default CUPS will use "[EMAIL PROTECTED]". # # ex: [EMAIL PROTECTED] # #ServerAdmin [EMAIL PROTECTED] # Classification (Classification) # # The classification level of the server.
