Nearly half of the billion dollars the U.S. government spends each year on office printing is unnecessary, according to a new survey. Federal employees spend $1.3 billion annually printing out documents, much of which they don’t really need. The potential for saving taxpayer dollars is substantial—$440 million a year—which represents four times the amount that President Barack Obama has ordered federal agencies to trim from their budgets. Another way of looking at the potential savings is this: $440 million is almost as much as the federal government spends each year to print money ($492.8 million).
