A character selection and impression control mechanism is provided with an integrated coded mechanical system of transmission for the orders controlling the character selection, the shift, the printing velocity and the "No-print" functions, between the frame of a typewriter and converter or decoding means supported on the carriage and controlling the devices performing these functions on said carriage. This system of transmission comprises a definite number of bails mounted on said frame for relative movements thereon and each adapted to cooperate with control means supported by the carriage for all the positions of said carriage along a line of writing. A number of said bails control the decoding device for the character selection and an additional bail controls the device for the "No-print" function. Still another bail controls the high and low printing velocity. One or the other of these two last mentioned bails, or both simultaneously, control equally the shift device for selecting one of two surface portions on the printing element.
