ABSTRACT:
The print data and the head shift data which instruct feeding of a print head input from a keyboard of a typewriter, are sequentially stored temporarily in a print buffer. Print processing or heat shifting is executed on the basis of the data sequentially read from the print buffer. In case the head shift data is stored continuously in the print buffer, the head shifting apparatus calculates finally the target position of the print head and shifts the print head to such position.
