Is this for real? According to this software blog, laser printer particle emissions can kill us. Has anyone heard anything about this?
Unless you're a secretary working the copy room, don't worry about it. It won't kill you, just increase your risk of COPD/emphysema. Your personal printer at home isn't going to kill you. I'm assuming these particulates are ink. You can't cough out ultrafine particulates. They act like asbestos.
