A:Answer The printers are similar, of course, but differ in connectivity options. The 2320 supports only USB, while the 2370 supports USB, WiFi, WiFi Direct, and wired Ethernet. The 2320 uses a TN630 or TN660 toner cartridge; the 2370 uses TN730/760/770.
Other differences: the 2370 can accept heavier bond, and has a slightly faster print speed (36 vs. 30 ppm).
