GreenPrint, the company with the paper-saving software that I've blogged about in the past is in the news with a new version of their software, this one called GreenPrint World, and it's now available as a free download on Download.com.
The sponsor-supported (thus free to end-user) package has been out there for about a week (though it appears the "1.0.1" version was just uploaded today, February 6th). So far Download.com is showing over 12,000 downloads, and yes, one of those is mine. I downloaded GreenPrint World 1.0.1 this morning, on my Vista laptop. I've been using GreenPrint on my other machines (Windows XP variants) for about a year now, and noticed very little difference with the new version, beyond the ads, of course. (See chart below.) In addition to the familiar page-saving functions, I was very happy to see the "create PDF" function still there in the free version -- a very easy-to-use feature that I find myself using more and more as time goes on.
My advice -- give it a try!
