Have you ever heard of the teleprinter? This device was once considered a new and revolutionary form of communication technology that changed the game for businesses, governments, and newsrooms around the world. Back in the day, the telegraph was the primary way for people to send and receive messages over long distances. However, the teleprinter totally revolutionized the process by allowing operators to instantly transmit printed text instead of just Morse code. And as we know, printing is much easier to read and understand than Morse code.
So, what exactly makes the teleprinter better than its predecessor, the telegraph? To start, the teleprinter enabled much faster communication. Where telegraphs with Morse code could transmit messages only several words at a time and had to be decoded at the other end, teleprinters could send entire sentences in a matter of seconds. Not only that, but the printed messages could be read immediately by the recipient, reducing the chance of transcription errors and making it much easier for the recipient to understand the message. Overall, this improved the efficiency of communication between individuals, companies, and governments, leading to increased productivity and streamlined operations.
With its advanced capabilities, it’s no wonder the teleprinter became an essential tool for communication. It allowed newspapers to receive breaking news faster, businesses to make quick deals with each other, and governments to send classified messages with speed and accuracy. Though it has since been replaced by even newer technologies, the teleprinter has undoubtedly left a lasting impact on the world of communication as we know it. So the next time you send a text or an email, remember that without the teleprinter, we might still be stuck decoding Morse code.
Definition of Teleprinter
A teleprinter, also known as a Teletype (TTY), is an electromechanical device used to transmit and receive typed information to and from a remote location. It employs a keyboard similar to that of a typewriter for inputting the message and a printer for outputting the received message. The teleprinter technology was developed in the early 1900s as an improvement over the telegraph, which only transmitted messages in Morse code.
The first teleprinters were developed in the United States in the 1910s and saw their greatest usage during World War II. They were used extensively by military forces for secure communication. Teleprinters continued to be used for commercial and military communication until the 1980s, when they were replaced by computer technology.
History of Teleprinter
The history of teleprinter machines dates back to the mid-19th century, when the telegraph was the primary means of long-distance communication. Initially, telegraph machines utilized Morse code, a system of dots and dashes, to send messages over long distances. However, this system required trained operators who could interpret the code and transmit messages accurately.
In the late 1800s, inventors developed new machines that could transmit messages over long distances without the need for skilled operators. One of the earliest of these was the “printing telegraph,” which used a keyboard to input messages and printed them out on a strip of paper. This early version was slow, but it paved the way for the development of more advanced teleprinters in the early 20th century.
Advantages of Teleprinter over Telegraph
- Speed: One of the key advantages of teleprinters over telegraphs was their speed. Teleprinters could transmit messages much faster than telegraphs, allowing for more efficient and timely communication.
- Accuracy: Teleprinters also offered increased accuracy over telegraphs. Because messages were typed and printed out, there was less room for errors or misinterpretation by operators.
- Less Skilled Operators Required: Another advantage of teleprinters was that they required less skilled operators. While telegraphs required operators who were trained in Morse code, teleprinters could be operated by individuals who simply knew how to type.
Evolution of Teleprinters
As teleprinters evolved, they became increasingly sophisticated and versatile. One of the major improvements was the ability to transmit non-English characters and symbols, allowing for international communication. Teleprinters also began incorporating the use of punched paper tapes, which allowed messages to be stored and transmitted automatically.
In the mid-20th century, teletype machines took the place of teleprinters and became the primary means of communication between computer systems. These machines could transmit data at even faster speeds, allowing for the rapid exchange of information across vast distances. Today, teleprinters are largely obsolete, replaced by modern digital communication technologies such as email and instant messaging.

Throughout their history, teleprinters played a crucial role in the evolution of long-distance communication. They provided faster, more accurate, and more efficient means of transmitting messages than previous technologies, and paved the way for modern communication technologies. While they are no longer in use, their impact on the history of communication remains significant.
Functions of Teleprinter
Teleprinters, or teletypewriters, were a significant technological improvement over telegraphs. They were widely used for communication purposes because they offered several benefits, like faster transmission of messages, accurate decoding, and remote printing. Here are some of the essential functions of teleprinters:
- Transmission Speed: Teleprinters could transmit messages at a speed of up to 100 words per minute, which was several times faster than the telegraph system. Faster transmission meant the message could be sent and received in real-time, significantly improving communication.
- Accuracy: Teleprinters were highly accurate because they used a system of binary codes for encoding and decoding messages. Binary systems could represent any character or symbol in the teleprinter’s repertoire, and this meant that errors in transmissions were reduced to a minimum.
- Remote Printing: One significant advantage of teleprinters was that messages could be transmitted from one location to another and then printed at the receiving end, eliminating the need for the sender to be present physically. This communication method was especially convenient for businesses that had to exchange information over long distances.
Teleprinter Keyboard and Printer
The teleprinter was made up of two essential components: the keyboard and the printer. The keyboard had 32 keys, one for each letter of the alphabet and one for numerals, punctuation marks, and control characters. The printer consisted of a rotating drum with 72 different character positions. As a character was typed on the keyboard, it was encoded into a binary code and transmitted over a telegraph or telephone line to a receiving machine.
At the receiving end, the binary code was transformed into a character and printed on paper. The teleprinter’s printer was activated by electrical impulses that generated a mechanical action, hammering the appropriate character onto a ribbon and then onto paper.
| Code | Character or Function |
|---|---|
| 00000 | NUL (Null) |
| 00001 | SOH (Start of Heading) |
| 00010 | STX (Start of Text) |
| 00011 | ETX (End of Text) |
The teleprinter revolutionized communication during the early twentieth century and set the foundation for modern computer technology. It was a vital link in the communication chain for businesses and government agencies and made it possible to transmit information and data over long distances with unparalleled speed and accuracy.
Advantages of Teleprinter
When the telegraph first entered the scene, it was a revolutionary advancement in communication. However, the teleprinter would later come and surpass it in many ways. Here are some of the advantages it brings.
- Faster transmission speed: With the teleprinter, messages could be transmitted at a much faster speed than the telegraph. This was due to the mechanized typing process, whereas telegraphs were sent through Morse code with sound. This speed increase made it easier for businesses and governments to send and receive important information quickly.
- More accurate transmission: Unlike the telegraph, teleprinters could transmit characters with nearly 100% accuracy. This was because the machine had a physical means of imprinting the message onto the paper tape. This accuracy was crucial for businesses and governments who needed to ensure the correct information was being sent and received.
- Ability to transmit non-English languages: With the telegraph, messages could only be sent using Morse code, which was limited to the English language. Teleprinters, however, had the ability to transmit messages using different languages and character sets, making it easier for people around the world to communicate with each other.
While these advantages are significant, one of the most interesting features of the teleprinter was its ability to transmit images using a unique code called Baudot code. This code used a six-bit character set to represent letters, numbers, and symbols, and allowed for the transmission of pictures using a series of dots and dashes.
