I got the Unified Driver (.gz) from http://www.samsung.com/us/support/owners/product/CLX-3185FW/XAA
I extracted the .gzip file in my home directory and took a terminal as root:
root@joost-laptop:/home/joost/cdroot/Linux# sh install.sh
The " Unified Linux Driver Installer" started and got a message: "Environment components necessary". In the 'Help Viewer' i read the message: " CUPS must be installed before Unified Linux Driver". Ubuntu software centre tells met that CUPS is installed.
The Unified Linux driver Installation wizard says it needs SANE (SANE stands for "Scanner Access Now Easy"). But my Ubuntu software centre says it is already installed. I took the option "Install Anyway" and it seems it installed correctly. Even printing a test page seems to function from the software point of view. Only my CLX-3185FW is not reacting. Didn't spit out anything. Anyone got 'n answer?
