Every font is designed with varying thicknesses and sizes, so there’s more ink consumption for a thicker font. There’s no simple rule–every case is different, but changing fonts to save a little money can help in the long run.

Serif fonts (like Times Roman, with the tiny legs on the letters) fare better than their Sans Serif counterparts (Arial, for example) on an economical level. For less text, Century Gothic takes less ink than Arial. More info on Yahoo.
