Ubuntu Print Server

The Common UNIX Printing System server's behavior is configured through the directives contained in the file /etc/cups/cupsd.conf. The CUPS configuration file follows the same syntax as the primaryconfiguration file for the Apache HTTP server, so users familiar with editing Apache's configuration file should feel at ease when editing the CUPS configuration file. Some examples of settings you maywish to change initially will be presented here.

Prior to editing the configuration file, you should make a copy of the original file and protect it from writing, so you will have the originalsettings as a reference, and to reuse as necessary.

Copy the /etc/cups/cupsd.conf file and protect it from writing with the following commands, issued at a terminal prompt:

sudo cp/etc/cups/cupsd.conf /etc/cups/cupsd.conf.original
sudo chmod a-w /etc/cups/cupsd.conf.original

ServerAdmin: To configure the email address of the designated administrator of the CUPS server, simply edit the/etc/cups/cupsd.conf configuration file with your preferred text editor, and add or modify the ServerAdmin line accordingly. For example, if you are the Administrator for the CUPS server, and youre-mail address is 'bjoy@somebigco.com', then you would modify the ServerAdmin line to appear as such:

ServerAdmin bjoy@somebigco.com

Listen: By default on Ubuntu, the CUPS serverinstallation listens only on the loopback interface at IP address 127.0.0.1. In order to instruct the CUPS server to listen on an actual network adapter's IP address, you must specify either a hostname, the IPaddress, or optionally, an IP address/port pairing via the addition of a Listen directive. For example, if your CUPS server resides on a local network at the IP address 192.168.10.250 and you'd liketo make it accessible to the other systems on this subnetwork, you would edit the /etc/cups/cupsd.conf and add a Listen directive, as such:

Listen 127.0.0.1:631 # existing loopback...
