Saving the Configuration File

When you save your printer configuration using printconf, it creates its own configuration file that is used to create the /etc/printcap file that the printer daemon (lpd) reads. You can use the command line options to save or restore this file. If you save your /etc/printcap file and overwrite your existing /etc/printcap file with the saved file, your printer configuration will not be restored. Each time the printer daemon is restarted, it creates a new /etc/printcap file from the special printconf configuration file. If you have configured a backup system for your configuration files, you should use the following method to save your printer configuration. If you added any custom settings in the /etc/printcap.local file, you should save it as part of your backup system also.

To save your printer configuration, type this command as root:

/usr/sbin/printconf-tui --Xexport > settings.xml

Your configuration is saved to the file settings.xml.

If you save this file, you can restore your printer settings. This is useful if your printer configuration is deleted, you reinstall Red Hat Linux and do not have your printer configuration file anymore, or you want to use the same printer configuration on multiple systems. To restore the configuration, type this command as root:

/usr/sbin/printconf-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 will be 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/printconf-tui --Ximport --merge < settings.xml

Your printer list will then consist 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 with the command /sbin/service lpd restart or by starting printconf and clicking Apply.
