Keyboard printer for typewriting characters on paper and recording the same on a magnetic tape. The printer keyboard has capacitive motionless keys. The printer has a rotative equipment including a striking mechanism and a pulse generator and produces one start pulse per rotation cycle of the equipment, character pulses equally distributed in the cycle and one key pulse per cycle corresponding to the capacitive character key actuated by the operator. The code of the struck character is the number of character pulses between the start pulse and the key pulse. This number is counted in the binary code and is recorded on the magnetic tape, using the character pulses as synchronization pulses. Means are provided for actuating the advance mechanism of the tape by signals derived from the character pulses, which avoids the necessity of a motor in the tape recorder.
