Duplex printing mode creates savings December 01, 2011 10:00 by John Sollars

A university in the US is saving money by changing the way it uses its printer ink and toner cartridges.

Arizona State University (ASU) has reduced energy usage and carbon emissions from its printing operations by switching devices to duplex mode.

A study by Canon shows that in the 2011 financial year, duplex printing saved the institution 725 trees and 2.34 million litres of water, and cut carbon emissions by more than 74 tonnes.

"We are grateful to have the support of the Canon team to help move ASU closer to our 2025 carbon-neutrality goal," said Ray Jensen, ASU sustainability operations officer.

"In one year, we were able to take 584 printers offline across ASU."

ASU has been able to increase the number of devices supporting duplex printing to 36 per cent, up from 19 percent in 2010, he added.

The ramp-up of duplex printing impacted around 90 per cent of the student population, with the remaining ten per cent needing their own printers.
