In this way, only LOCAL hosts can access cupsd on a CUPS server. LOCAL hosts are
hosts whose IP addresses belong to a non-PPP interface (interfaces whose
IFF_POINTOPOINT flags are not set) and whose IP addresses belong to the same
network as the CUPS server. Packets from all other hosts are rejected immediately.
cupsd Activated by Default
In a standard installation, cupsd is activated automatically, enabling comfortable access
to the queues of CUPS network servers without any additional manual actions. The

Functionality for BrowseAllow and BrowseDeny"
for this feature, because otherwise the security would not be sufficient for an automatic
activation of cupsd.
24.6.3 PPD Files in Various Packages
The YaST printer configuration sets up the queues for CUPS using only the PPD files
installed in /usr/share/cups/model/ on the system. To find the suitable PPD
files for the printer model, YaST compares the vendor and model determined during
hardware detection with the vendors and models in all PPD files available in /usr/
share/cups/model/ on the system. For this purpose, the YaST printer configuration
generates a database from the vendor and model information extracted from the PPD
files. When you select a printer from the list of vendors and models, receive the PPD
files matching the vendor and model.
The configuration using only PPD files and no other information sources has the advan-
tage that the PPD files in /usr/share/cups/model/ can be modified freely. The
YaST printer configuration recognizes changes and regenerates the vendor and model
database. For example, if you only have PostScript printers, normally you do not need
the Foomatic PPD files in the cups-drivers package or the Gimp-Print PPD files
in the cups-drivers-stp package. Instead, the PPD files for your PostScript
printers can be copied directly to /usr/share/cups/model/ (if they do not already
exist in the manufacturer-PPDs package) to achieve an optimum configuration
for your printers.
