location of printer config files

Hi, I would like to know the location of the files of the settings of the printer. A printer was used previously by my PC, but now it is not possible to use the graphical interface just the command line. Hence, I can not see the details of the printer (IP address, etc). How can I find information of an existing printer setting? Version: 12.2.

The printer configuration parameters (including URI) are located in /etc/cups/printers.conf, and the associated PPD is located in the /etc/cups/ppd/ directory.
