The first time I used a real electric typewriter (IBM Selectric), boy did that mess up my timing. As I recall the reason for the delay was that the system used a form of error detection called echoplex-the character was sent to the computer and echoed at the computer back to the TTY at which point it was printed. The human was the detect and correct mechanism. Obviously this mechanism was outdated the minute the TTY was moved any distance from the computer.
