9.3 Installing the Software
PPD (PostScript printer description) is the computer language that
describes the properties, like resolution, and options, such as the
availability of a duplex unit. These descriptions 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 openSUSE, 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
Section 9.7.2, PPD Files in Various Packages and
Section 9.8.2, No Suitable PPD File Available 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
Adding Drivers with YaST, (↑ Start-Up )). Subsequently, 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
openSUSE 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
