GreenPrint prepares to launch a Mac version of its paper-saving software.

One year after introducing a free version of its paper- and ink-saving software, GreenPrint is preparing to launch two new offerings. This fall, the Portland-based company plans to release a Mac version and an updated version of its Enterprise software.

GreenPrint, which aims to help businesses and individuals eliminate paper waste when printing documents, expects to roll out GreenPrint 2.0 beta in September, and the Mac-specific software in October. The moves are expected to boost revenue to $5 million to $10 million within 12 months, according to the company’s founder Hayden Hamilton.

If all new computer users installed the software, they could save 36 million trees per year, reducing carbon dioxide emissions by 117 million tons, according to the company.

Green Print’s Enterprise software highlights and removes unwanted pages and tracks the pages, money and CO2 emissions saved with each print job. GreenPrint 2.0 offers improved accuracy in figuring how much of a print job is wasted, as well as more detailed reporting, tracking and management functions, Hamilton says.

About 100 companies are currently doing trials of the software, representing as much as $30 million in potential deals. If sales go well, the company’s revenue within five years could reach at least $50 million and as much $100 million, according to Hamilton. Xerox (NYSE: XRX) in November 2007 began partnering with GreenPrint as a way to help customers save paper and ink.

Consumers, who have downloaded about 90,000 copies of the first version of the software, have been the main drivers of the company’s revenue so far, but Hamilton says he expects big companies, nonprofits and other organizations will be the purchasers who will push the boot-strapped company to profitability.
