An interesting new innovation from Xerox called the “erasable paper” will allow you to print off those figures for the meeting with management, or those speakers notes for your presentation, and literally “leave them to erase” over the next 24 hours. The patented technology, still in development, works such that the image printed on paper fades naturally over time with exposure to light, or quickly with exposure to heat. Many practical uses for this in offices where people print out documents for temporary use, as long as the “erasing” method can be made easy and efficient.
