Bluetooth is a wireless technology that allows two or more electronics to communicate without wires. Bluetooth uses radio signals in the 2.4 GHz range and comes in two classes. One class is capable of transmitting signals as far as 33 feet while the other allows for the transmission of data more than 300 feet. Bluetooth is used in printers to allow for effortless cordless and wireless printing. Bluetooth printing provides an easier way for your device to pass on print jobs to your printer without the need for any physical connections.
