Software saves trees, cash and headaches, says creator

It's happened to all of us: You print something from the Web, and all you get is a sheet of paper with nothing but a URL or something equally useless.

New software is designed to prevent printing blank pages from the Web, its inventor says. This printing pain in the neck happened to Hayden Hamilton so much that he invented a solution: GreenPrint, software that analyzes what a computer sends to a printer.

It looks for pages that have no type or just a few lines of type (users can set the parameters). Then, the software automatically eliminates these pages from the print job.
