(KSL News) A new study suggests certain laser printers could be harmful to your health.
Researchers in Australia discovered some printers emit an ultrafine powder into the air, made up of toner material. They say the particles are so tiny, people can inhale them deep into their lungs.
The study shows the worst printer put out as many particles as a lit cigarette.
Most of the printers on the list are made by Hewlett Packard. The company says it is reviewing the research.
But a doctor says the study did not look at the effects of longterm exposure and says many particles crossing into our blood are not dangerous.
