Which code is most commonly used in modern printing telegraphy?

The most commonly used code in modern printing telegraphy is the Baudot Code. This code was developed in the late 19th century specifically for telegraphy and has the advantage of allowing the transmission of characters with a limited number of bits, significantly enhancing the efficiency of data communication.

Baudot Code operates by using a five-bit code to represent different characters, which allows for the transmission of a variety of textual data. Its design is particularly well-suited for systems where space and bandwidth are limited, making it a preferred option for telegraphic communications, especially in practical applications.

In contrast, ASCII (American Standard Code for Information Interchange) is more commonly used in modern computer systems for text encoding, but it is not specifically tailored for telegraphic use. Morse Code, while historically significant in the realm of telegraphy, relies on dots and dashes to convey information and is not as efficient for high-speed printing systems. ETX Code relates more to control signals in data transmission rather than character encoding for telegraphs.
