637Chapter 25Running a Print Server .CUPS offers a Web-based interface for adding and managing printers. You canaccess this service by typing localhost:631from a Web browser on the com- puter running the CUPS service. (See the section titled Using Web-Based CUPSAdministration, later in this chapter.) The KDE desktop comes with a tool formanaging CUPS server features. To launch the KDE CUPS Server Configurationwindow, type /usr/bin/cupsdconffrom a Terminal window. .You also can configure CUPS manually (that is, edit the configuration files andstart the cupsd daemon manually). Configuration files for CUPS are contained inthe /etc/cupsdirectory. In particular, you might be interested in the cupsd. conffile, which identifies permission, authentication, and other informationfor the printer daemon, and printers.conf, which identifies addresses andoptions for configured printers. Use the classes.conffile to define localprinter classes. You can print to CUPS from non-UNIX systems as well. For example, you can use aPostScript printer driver to print directly from Windows XP to your CUPS server. Youcan use CUPS without modification by configuring the XP computer with aPostScript driver that uses http://printservername:631printers/targetPrinteras its printing port. To use CUPS, you need to have it installed. Most Linux distributions let you chooseto add CUPS during the initial system install or will simply add CUPS by default. IfCUPS was not added when you first installed your Linux distribution, check youroriginal installation medium (DVD or CD) to see if it is there for you to install now. Fedora, Slackware, SUSE, and other Linux distributions all have CUPS on the firstCD or DVD of their installation sets. Setting Up PrintersWhile it is usually best to use the printer administration tools that are specificallybuilt for your distribution, many Linux systems simply rely on the tools that comewith the CUPS software package. This section explores how to use CUPS Web-basedadministration tools that come with every Linux distribution and then examines theprinter configuration tool system-config-printer that comes with Fedora and RedHat Enterprise Linux systems for setting up printers. Using Web-Based CUPS AdministrationCUPS offers its own Web-based administrative tool for adding, deleting, and modify- ing printer configurations on your computer. The CUPS print service (using the cupsddaemon) listens on port 631 to provide access to the CUPS Web-based administrativeinterface. Note34_
