Are laser printers dangerous to your health?
I've been sitting next to two huge laser printers for the past month or so. Like one foot away and three feet away. Is there anything toxic about sitting this close to them

You probably don't have too much to be concerned about, unless you are printing pages all day, and breathing it in all day. Just think, if you live in a big city and you stand outside working on the concrete and roads all day, or in dusty construction zones or coal mines, there are certainly worse things worse for your health. There are people who smoke all day, and that's certainly worse than any laser printer you can imagine.
To my knowledge nobody has ever died or become seriously ill from sitting next to a laser printer unless they do some crazy things like inhaling all day. This is just like them saying mobile phones are bad for your health, or any home appliance is bad for your health. If there's anything they could say that's bad for you, they could say it! However, just to be extra cautious, you may want to sit more than a foot away from this laser printer if you can, open a window to get some fresh air flowing in, or get one of those fancy air purifiers, and then you might really see how much dus this laser printer is emitting.

I would say, a firm...maybe:http://blogs.zdnet.com/BTL/?p=5855
"Citing inadequate scientific techniques for particle analysis as well as HP’s performance within certain international standards and guidelines, the company is disputing the claims of the Australian researchers. Those researchers discovered the problem by chance when “an investigation of office ventilation systems, carried out jointly between the university and the Queensland Department of Public Works, found five times as many particles indoors as those produced by traffic outdoors. Using an electronic sniffer, researchers traced the emissions to printers.” As can be seen from the response below, HP notes that even the emissions from toasters cannot be “accurately characterized,” thus drawing into question any conclusion that the emissions from laser printers could pose health risks."

"he IARC evaluated carbon black, as a Group 2B carcinogen, for which
there is inadequate human evidence, but sufficient animal evidence. The
latter is based upon the development of lung tumors in rats receiving
chronic inhalation exposure to powdered carbon black at levels that
induce particle overload of the lung. However, there is a two-year
inhalation study of a toner containing carbon black which demonstrated
no association between toner exposure and tumor development in rats."

Particulate inhalation is always a potential issue, not even necessarily from a carcinogenic perspective. Diesel exhaust and other similarly-fine particulates have been shown to be harmful. Toner is made up of very fine carbon-based particles, along with other chemicals to help it set and bond to the paper when heated. It's not a huge leap to say that one should probably limit their exposure, if for no other reason that excessive exposure to anything is not necessarily good.

One time at work, a coworker and I had to take apart a laser printer that was malfunctioning. Apparently, the toner cartridge was defective as the instant we pulled it out of the printer, the air was filled with colored toner. As luck would have it, I was having sinus problems, and later that day, when I blew my nose, my mucus came out blue.It was pretty creepy. But it didn't make me sick otherwise!

According to an article on WebMD, they pose a potential health risk:"Some home and office laser printers emit possibly harmful amounts of small-particle air pollution, Australian researchers find.
"The very fine particles emitted by laser printers could be a problem, as such small particles can be inhaled deep into the lungs."
