I didn't advise not to install a fume extractor if you so desire.
You might want one for all of the other chemicals in your house than because paints and many other cleaners in a house are just as dangerous.
I believe it would be important to not be inhaling the fumes from a printer if you have your head in the printer. If you are printing and walk away from it and there is a slight odor I don't believe a fume extractor is warranted. I've been in large injection molding operations and have yet to see a fume extractor around a machine even with an operator close to the machine here in the US.
