Bluetooth vs. WiFi Printers. Bluetooth uses a low power wireless networking protocol to connect devices within close range, generally no further than ten meters. While most contemporary laptops come equipped with WiFi adapters, Bluetooth is a little less common.

WiFi printers are accessible over a WiFi network. Wi-Fi normally uses a similar radio band to Bluetooth, but with more power. Devices that connect over a Wi-Fi network must be within about 100 meters to wireless access point. Using WiFi to connect to your printer is more appropriate if you have a larger office space with more employees
