the 2nd option allows me to locate the directory where the drivers are found. I don't know where they are at? I tried searching for PPD files, and found them for our HP-laserjet computer but don't see them for the mp280. the hp laserjet is found in file system/etc/cups/ppd directory.
Can someone help me!
The .ppd file you're looking for should be located in /usr/share/ppd
