hi
i am trying to install printer (lexmark z12) first of all i run "sudo cupsd" to run CUPS. after that i started printing manager and click on add a printer. I found the printer lexmark Z12 but when i select it and click next, it says "unable to load driver...wither driver doesnot exist or you do not have permission to access it"
