I'd trust your nose. If you can smell it printing, it means you're smelling the outgassing of unburnt and burnt plastics. You could also get a pm10 and pm2.5 air quality monitor for a more scientific measurement. Gasses won't trigger those, depending on what they are.. I guess you could make a forced air device with 20 sensors in it, but nothing on the market is like that. As for limited exposure, it's probably not too bad. But uncovered in bedroom... Whole different story.
