置。A character code generator that generates a character code corresponding to the character each time a character mark occurs, a memory that stores one line of print data, and a comparison to see if the character code and the print data match. a shift register circuit that receives the data output from the comparator, and a printing means that receives the output of the shift register circuit and prints the data, and converts the data output of the comparator into two bits in series. The apparatus includes means for detecting a storage shift register and a parallel output of the shift register with an AND circuit, and inhibiting the output of the comparator using this output, to prevent blank digits from being narrowed and printed at the same time.
