Still not fixed in Ubuntu 11.04 (at least for CLP-300 printer). The solution is same: (may be helpful for new users) 1. system-config-printer set up your CLP-300 with default settings. make sure 600 dpi mode selected. close. 2. sudo gedit /etc/apt/sources.list add line deb http://www.openprinting.org/download/printdriver/debian/ lsb3.2 main contrib main-nonfree 3. sudo apt-get update 4. sudo apt-get install openprinting-splix 5. system-config-printer Make and model -> Change select CLP-300 and you'll see two option at right pane, select SpliX. Now duplex is work.
