Particle Emission Characteristics of Office Printers

From ES&T Online News:

When researchers in Australia discovered that particulate matter levels were five times higher during the workday inside a nonsmoking office building than outside near a freeway, they looked for indoor culprits. After testing more than 50 printers throughout the building, they found that particle emissions varied depending on the type and age of the printer. In one case, standing near a working printer was much like standing next to a cigarette smoker.
