Sidepocket_Pro sent us a link to this HP press release which reads, "Based on our own testing, HP knows that many variables can affect the outcome of tests for ultrafine particle emissions. Although HP is not aware of all of the specific methodologies used in the Queensland study, based on what we've seen in the report — as well as our own work in this area — we do not believe there is a link between printer emissions and any public health risk. Specifically, HP does not see an association between printer use by customers and negative health effects for volatile organic compounds, ozone or dust. While we recognize ultrafine, fine, and coarse particles are emitted from printing systems, these levels are consistently below recognized occupational exposure limits."
