Printing telegraph

House's telegraph could transmit around 40 instantly readable words per minute, but was difficult to manufacture in bulk.The benefit of the Printing Telegraph is that it allows the operator to use a piano-style keyboard to directly input the text of the message.This is in contrast to the telegraphs that used Morse Code dots and dashes which needed to be converted into readable text.[7] The Globotype was invented by David McCallum as a response to problems with the printing telegraph.[8] Various layouts were produced to improve the efficiency of the keyboard system and accommodate several other alphabets.
