Laser Printers: Dangerous Emissions

Laser Printers: Dangerous Emissions

Australian air-quality inspectors studied the emissions of 62 laser printers. They found that 27% of laser printers emitted toner grains into the air. Toner tiny grains when breathed into the lungs could be compared to second-hand smoke. Some laser printers' emissions were dense enough to almost match pollution from second-hand cigarette smoke.
