How fast do VOC's dissipate outside?

Just moved my printer near a window so I can set up a hose to vent VOC's outside from my chamber. My question is this, how fast do they dissapte? I ask because there are two windows right next to each other, and it's summer. So closing both of those windows isn't really an option. Will the VOC's just immediately blow back in the other window? Or do they dissipate rapidly once out in open air?
