Printer manufacturers primarily profit from ink and toner sales, not the devices themselves. Years ago, a college student's viral experiment highlighted font choices for ink efficiency, claiming the U.S. government could save $500 million annually by adopting Garamond. While Garamond uses less ink, its readability drops at small sizes, often requiring larger text that increases consumption.
Though the claims were overstated, interest in low-ink fonts endures. Tests show certain designs consume far less. Prioritize 'Thin,' 'Condensed,' or 'Narrow' variants, plus simple styles sans flourishes or heavy serifs. Here's a curated list based on real-world studies and usage:
Often underappreciated, Century Gothic delivers crisp readability with minimal ink thanks to its clean sans-serif lines. No ornate details means pure efficiency. Note: Its wider character spacing uses more paper, balancing out some savings.

Engineered for sustainability, Ecofont® incorporates microscopic holes in letters, slashing ink use by up to 33% while preserving legibility across sizes. Ideal for eco-conscious printing.
This typewriter-inspired classic features slim strokes originally optimized for ink ribbons. Unlike Garamond, Courier stays sharp even small, extending cartridge life reliably.

Developed by UK retailer Ryman Stationery, this free font mirrors Ecofont's hollow-letter technique, cutting ink by 33% versus standards. Subtle voids vanish at small sizes, ensuring aesthetics and function.

The familiar default shines in efficiency. Consumer Reports found it uses 27% less ink than Arial. No need for drastic changes—stick with it for proven savings.
