unless you take care that it is protected by special rewall rules and secure settings
in the CUPS conguration.
14.7.2 PPD Files in Various Packages
The YaST printer conguration sets up the queues for CUPS using the PPD les in-
stalled in /usr/share/cups/model. To nd the suitable PPD les for the printer model,
YaST compares the vendor and model determined during hardware detection with
the vendors and models in all PPD les. For this purpose, the YaST printer congura-
tion generates a database with the vendor and model information extracted from
the PPD les.
The conguration using only PPD les and no other information sources has the ad-
vantage that the PPD les in /usr/share/cups/model can be modied freely. For ex-
ample, if you only have PostScript printers, normally you do not need the Foomatic
PPD les in the cups-drivers package or the Gutenprint PPD les in the gutenprint
package. Instead, the PPD les 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 conguration for your printers.
14.7.2.1
CUPS PPD Files in the cups Package
The generic PPD les in the cups package have been complemented with adapted
Foomatic PPD les for PostScript level 1 and level 2 printers:
•
/usr/share/cups/model/Postscript-level1.ppd.gz
•
/usr/share/cups/model/Postscript-level2.ppd.gz
14.7.2.2
PPD Files in the cups-drivers Package
Normally, the Foomatic printer lter foomatic-rip is used together with Ghostscript
for non-PostScript printers. Suitable Foomatic PPD les have the entries *NickName:
... Foomatic/Ghostscript driver and *cupsFilter: ... foomatic-rip. These PPD
les are located in the cups-drivers package.
YaST generally prefers a manufacturer-PPD le. However, when no suitable
manufacturer-PPD le exists, a Foomatic PPD le with the entry *NickName: ...
Foomatic ... (recommended) is selected.
14.7.2.3
Gutenprint PPD Files in the gutenprint Package
Instead of foomatic-rip, the CUPS lter rastertogutenprint from Gutenprint (formerly
known as GIMP-Print) can be used for many non-PostScript printers. This lter and
suitable Gutenprint PPD les are available in the gutenprint package. The Gutenprint
PPD les are located in /usr/share/cups/model/gutenprint/ and have the entries
*NickName: ... CUPS+Gutenprint and *cupsFilter: ... rastertogutenprint.
