Lasers are hazardous to your health.

Possibly true. A study published by the Queensland University of Technology several years ago found that laser printers emit tiny particles into the air. The resulting particulate pollution is comparable, under certain conditions, to the air near a busy road. Emissions rates were found to vary by the vendor and the age of the printer. Follow-up research indicated that those emissions have something to do with the paper being heated inside the printer, before the toner is applied.

In theory, those ultrafine particles emitted by lasers could have the same kinds of health effects as other small particles—such as those in cigarette smoke or polluted air. But those health hazards have not yet been definitively established. In the meantime, researchers recommend moving printers—particularly those that get heavy use—away from areas where people sit; wherever you put your laser, it should be well-ventilated areas.
