Ways in which teleprinters were used Teleprinters could use a variety of different communication channels. These included a simple pair of wires, public switched telephone networks, dedicated non-switched telephone circuits (leased lines), switched networks that operated similarly to the public telephone network (telex), and radio and microwave links (telex-on-radio, or TOR).
