Oops! Someone should get in front of this one.

Jim Lyons Observations: Australian toner fears are back:
"So far the general and business press is slow to pick up on the story, with just a few mentions as of mid-afternoon US Time. ABC Australia's excellent 'Laser printer debate heats up' recaps the history of the story and has a current comment from HP (NYSE HPQ) press agency Burson-Marsteller, pointing out HP's interest in research the danger of ultra-fine particles (UFPs) in the office but also expressing skepticism towards a direct correlation between toner and paper and UFPs.

I have not gained access to the entire article as of yet, but here's an introductory quote from the abstract:

While current research has demonstrated that the operation of some laser printers results in emission of high concentrations of ultrafine particles, fundamental gaps in knowledge in relation to the emissions still remain. In particular, there have been no answers provided to questions such as the following: (1) What is the composition of the particles? (2) What are their formation mechanisms? (3) Why are some printers high emitters, while others are low? Considering the widespread use of printers and human exposure to these particles, understanding the process of particle formation is of critical importance. This study, using state-of-the-art instrumental methods, has addressed these three points."
