...study, Lidia Morawska, a physicist at the Queensland Institute of Technology, and her colleagues analyzed printer emissions in a large open-plan office environment. The good news was that 60% of the printers they tested, including eight HP LaserJet 4050 models, four Ricoh Aficio models and one Toshiba Studio, did not emit any particles. But of the 40% that did, many, such as the HP LaserJet 1320 and 4250 models, were classified as "high-level emitters." Emissions, researchers found, were printer-specific and fluctuated depending on the age of the toner cartridge and the amount of toner a document required...
...done any recent research on the health effects of printer emissions - Morawska's study is the most extensive to date - but Sharon Worthy of the U.S. Dept. of Labor says "historically laser printers have presented no known hazard in the workplace." But, according to the Washington-based nonprofit Environmental Working Group, which has conducted research on particulate pollution from automobiles, printers release the same type of fine particles that cars do. "What we need are standards up front so that the pollution we're subjected to don't pose health risks," says Jane Houlihan, the nonprofit's vice president...
