I would try to install "Printer setting Utility (Driver) (ver.2.01.03:15)". When you download the software it will consists of filename PSU_1.13.tar.gz
So if you're running Ubuntu go to places and start the Nautilus file manager, right mouse click on "PSU_1.13.tar.gz" and select extract. The extracted file will create a sub-directory named "cdroot". Change directory to cdroot/Linux/psu
In the "cdroot/Linux/psu" directory you will see files install.sh and uninstall.sh
Make sure the install.sh is executable, if it is not then you can open a terminal and type "chmod 755 install.sh"
In the same terminal type "sudo ./install.sh"
The install.sh script should run, and now regarding the model type. This driver may or may not work, but in the past I've had similar drivers work. Also, you should be running Ubuntu 10.04 or 12.04 for the most comprehensive set of printer drivers. I found that the LTS version of Ubuntu usually has some of the latest printer drivers. I just started upgrading computers at home from Ubuntu 10.04 to 12.04. I'm really starting to like 12.04 a lot. However, I recommend 10.04 for the maturity and stability.
