Seamlessly integrated with Microsoft Office, Internet Explorer, Firefox, & Chrome, PrintEco allows users to easily practice responsible paper usage, while also saving time and money.

As part of the agreement, Domtar will be the exclusive paper company sponsor of PrintEco's flagship product, which led to PrintEco being named one of Entrepreneur Magazine's 100 Brilliant Companies.
