PPD (PostScript Printer Description) is the computer language that describes the properties (such as resolution) and options (such as duplex unit) of PostScript printers.
These descriptions are necessary to use the 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, a lot of PPD files are preinstalled. In this way, even printers that do not have built-in PostScript support can be used.
If a PostScript printer is configured, the best approach is to get a suitable PPD file and store it in the directory /usr/share/cups/model/ or add it to the print system with YaST (preferred approach). You can then select the PPD file during the installation.
Be careful if a printer manufacturer wants you to install entire software packages. This kind of installation results in the loss of the support provided by SUSE LINUX.
In addition, print commands might work in a different way than before and the system might not be able to address devices from other manufacturers.
