Computer printers as harmful as cigarettes: Aussie scientists

Beware, computer users! Your office printer could be posing as much danger to your lungs as a drag on a cigarette, according to Australian scientists.
After an investigation, researchers from Queensland University of Technology have revealed that some laser printers emit potentially dangerous levels of tiny toner-like materials in the air which could harm one’s lungs.
These ultra-fine particles are capable of infiltrating the lungs and causing lasting damage on the scale of inhaled cigarette smoke, ‘Sydney Morning Herald’ quoted researcher Prof Morawska as saying.
According to her, These (printer) particles are tiny like cigarette smoke particles and, when deep inside the lung, they do the same amount of damage.The health effects from inhaling ultra-fine particles depend on particle composition, but the results can range from respiratory irritation to severe illness such as cardiovascular problems or cancer.”
The conclusion came after the university’s International Laboratory for Air Quality and Health examined 62 printers and found that 17 were highparticle emitters. The study, published in the American Chemical Society’s Environment Science and Technology journal, found indoor particle levels in the office air increased five-fold during work hours due to printer use.
Printers emitted more particles when the toner cartridge was new, and when printing graphics and images as they require greater quantities of toner, Morawska was quoted.

I don’t even use a printer and I don’t really understand all of the people who do use them. I haven’t had a printer in 5 years and have been just fine without it. I don’t work in an office and I probably would want one their. But people who have a printer at home confuse me, they only use it like once a year and that is about it, what’s the point of spending the money on it?

I did not know that using laser printers can be as dangerous as smoking. But I have discovered a smoke alternative called e-cigarette. It has the same look, touch and feel of a real cigarette, but you have the freedom to smoke anywhere because it does not emit real smoke, only vapor!

Anyway, 2nd hand smoke and computer printer emissions are bad for the health. The negative thing is we can stop smoking but we cant stop using printers especially when we are in the office.

Makes sense, having the toner get into your lungs could be bad in an enclosed area.

Interesting article however i think you could say a lot of things are harmful when you thin about it. Many things we come into contact on a daily basis give off fumes. We even buy such thinks on purpose for example deodorant.

I think its quite shocking to hear from you that printers can be as dangerous as smoking cigarettes. The printer manufacturers must look into this matter and act quickly to resolve this problem ASAP as we cannot live without printers and they are being used in homes now a days which means innocent little children are also the victims of its harmful affect. Thanks for posting.

@pain after surgery

I agree with your insight. Since it is proven that computer printers can be dangerous like cigarettes according to Australian experts, the manufacturers must do something about this and consult with the technological experts.
