According to a Huff Post Education article,

Fourteen-year-old Suvir Mirchandani has adapted his sixth-grader science fair project from Dorseyville Middle School in Pittsburgh — a study of the cost savings incurred by switching the font in his school’s paper handouts — to show exactly how much money the bigwigs in Washington, D.C., could save if they followed suit.

Spoiler alert: It’s a lot.

His project showed that switching the school’s paper font from Times New Roman to Garamond would save his school about $21,000 a year in ink costs.

Suvir tested his font theory with five documents from the Government Printing Office (GPO) and concluded that switching the government documents’ fonts from Times New Roman and Century Gothic (used on all government documents) exclusively to the more space-efficient Garamond would greatly cut costs in ink expenditure for both state and federal governments. The font point size remained the same in the study. He predicts the federal government would save roughly $136 million a year, and state agencies could collectively save up to $234 million annually.

It’s not a bad idea.  Members of Congress don’t read reports, budgets, and proposed legislation anyway.  Hell, the federal government should just “go all the way” and print everything in 8-point Onyx.
