Installing The Software - Novell LINUX ENTERPRISE SERVER 11 - ADMINISTRATION Administration Manual

WARNING: Changing Cable Connections in a Running System
When connecting the printer to the machine, do not forget that only USB de-
vices can be plugged in or unplugged during operation. To avoid damaging
your system or printer, shut down the system before changing any connections
that are not USB.

10.3 Installing the Software

PPD (PostScript printer description) is the computer language that describes the prop-
erties, like resolution, and options, such as the availability of a duplex unit. These de-
scriptions are required for using various printer options in CUPS. Without a PPD file,
the print data would be forwarded to the printer in a "raw" state, which is usually not
desired. During the installation of SUSE Linux Enterprise Server, many PPD files are
preinstalled.
To configure a PostScript printer, the best approach is to get a suitable PPD file. Many
PPD files are available in the package manufacturer-PPDs, which is automatically
installed within the scope of the standard installation. See
in Various Packages"
for a PostScript Printer"
New PPD files can be stored in the directory /usr/share/cups/model/ or added
to the print system with YaST (as described in Section "Adding Drivers with YaST"
(Chapter 8, Setting Up Hardware Components with YaST, ↑Deployment Guide)). Sub-
sequently, the PPD file can be selected during the installation.
Be careful if a printer manufacturer wants you to install entire software packages in
addition to modifying configuration files. First, this kind of installation would result in
the loss of the support provided by SUSE Linux Enterprise Server and second, print
commands may work differently and the system may no longer be able to address devices
of other manufacturers. For this reason, the installation of manufacturer software is not
recommended.
