Location of printer driver files identified by Gnome
I notice that when I install a printer driver from the cd-rom, this file is extracted to /usr/share/cups/model.
I would like to move this file to the directory containing all the files pointed to by Gnome when you go through the GUI to set up a printer. I need to do this (I think) because Gnome does not allow me to select the printer driver I need (a Samsung Color Laser driver) from the available lists. Now that I have installed the file to the directory listed above, I can neither select the file upon setup nor-- and this is frustrating-- reinstall it. When I attempt the latter action, I get the message that the file is already installed. So where are those files that Gnome brings up? I have found the right file in /usr/share/ppd/Samsung, but all the files in this directory are zipped files. Where are the extracted files?
I am perplexed.
