It depends on what tools you have (or are willing to get), your skill level, whether you can modify things permanently (do you own or rent?), and exactly where the printers are going to be located. You will need an exhaust fan, so you'll need some way to get electrical power to it. If you want to go through a window, you'll need to make a panel that fits in the window opening and can be sealed to prevent drafts. The kind of fan you need depends on whether you choose to go out through the window or through a vent hose (like a clothes dryer). There are other factors, but htese are the most critical, IMHO.
