WiFi is far too slow to be used routinely (several minutes to start printing a color page picture 6MB), but it can help. The permanent connection to a USB hub to the computer is the fastest and easiest connection (-10s waiting for the same page). The new more expensive inks really give a good record for this range. The printer heater CLX3175 more than I had before and it seems necessary to put heavy paper if you want to do duplex (manual, I said, because no automatic on this machine). Scan perfectly fine for a teaching use. Always as simple installation on Mac.
