I saw this link today about how they have come out with a printer that can erase and reuse documents (http://greenopolis.com/goblog/jerryjamesstone/new-desktop-printer-can-erase-and-reuse-documents ). The idea is awesome but the printer itself is very costly as well as the "paper". It is a step in the right direction. What do you think of this idea? Do you think that it will become more common so that it does not cost so much?

Along these lines, I just found out that the font type Century Gothic uses 30% less ink than other font types. This doesn't address the issue of paper, but think about all of the ink you could save!!! (and at a much lower cost than the printer and paper mentioned here)
