Perhaps some laser printers ought to carry a health warning like those you see on many cigarette packs.
A team of Australian scientists carried out tests on a range of printer models and found that a third of them emit tiny particles of material that can get into the lungs and cause health problems.
The printers that were used in the research were located in an open plan office. I don't care much for open plan offices and this research finding provides yet another reason to avoid them, in my opinion. The levels of the particles released by the printers in the study showed a 500 percent increase during working hours.
