I came across this report recently and found it interesting since I use many of these products. The International Laboratory for Air Quality and Health, Queensland University of Technology did a study to determine how much particle emission and other matter is emited by laser printers. Most printers did well, but some printers commonly used in business environments could be making you sick. Click here to get the article and study.
