Abstract

An electric typewriter includes a RAM memory for storing selected characters to be printed and for storing data relating to the present escapement position and future escapement destination of a printing head of the typewriter. A control unit operates a printer to print the stored characters in the memory unit and, when a power interrupt occurs and power is subsequently restored, the control unit accesses particular position data in the memory in accordance with the angular position of a print shaft of the typewriter at the time of the power interrupt. The accessed data is employed to define a proper return escapement position for the printing head of the typewriter.
