ex.: on Ubuntu 11.04 - how can I install ecofont?
You cant install ecofonts to replace your fonts automatically because the software is made for Windows only but you can use the TTF installed in the windows version to be used on your documents:
Or you can just double click on the ttf file and click install:
After that you will be able to use the ecofonts on your documents and print them instead of the normals ones available.
