Abstract : The development and test results of the first Soviet on-the-fly printer APM-1 are reported. The high-speed line printer uses a continuously rotating print wheel carrying 24 characters; they are selected by a 5-digit binary code. Fast-acting hammers print the characters. The printer is connected to the computer via a control unit which comprises ferrite-diode logical elements and semiconductor amplifiers. Functional and principal circuits of this unit are presented and their operation is briefly explained. During the two-year operation of an APM-1 on-the-fly printer prototype, no failure of a major component occurred.
