When the printer configuration is saved using the Printer Configuration Tool, the application
creates its own configuration file that is used to create the files
in the /etc/cups/ directory. You can use
the command line options to save or restore the Printer Configuration Tool file. If the
/etc/cups/ directory is saved and
restored to the same locations, the printer configuration is not
restored because each time the printer daemon is restarted, it
creates a new /etc/printcap file from the
Printer Configuration Tool configuration
file. When creating a backup of the system's configuration files,
use the following method to save the printer configuration
files.
To save your printer configuration, type this command as
root:
/usr/sbin/system-config-printer-tui --Xexport > settings.xml
|
Your configuration is saved to the file settings.xml.
If this file is saved, it can be used to restore the printer
settings. This is useful if the printer configuration is deleted,
if Red Hat Enterprise Linux is reinstalled, or if the same printer
configuration is needed on multiple systems. The file should be
saved on a different system before reinstalling. To restore the
configuration, type this command as root:
/usr/sbin/system-config-printer-tui --Ximport < settings.xml
|
If you already have a configuration file (you have configured
one or more printers on the system already) and you try to import
another configuration file, the existing configuration file is
overwritten. If you want to keep your existing configuration and
add the configuration in the saved file, you can merge the files
with the following command (as root):
/usr/sbin/system-config-printer-tui --Ximport --merge < settings.xml
|
Your printer list then consists of the printers you configured
on the system as well as the printers you imported from the saved
configuration file. If the imported configuration file has a print
queue with the same name as an existing print queue on the system,
the print queue from the imported file will override the existing
printer.
After importing the configuration file (with or without the
merge command), you must restart the
printer daemon. Issue the following command as root:
/sbin/service cups restart
|
