When data, which is not usually printed, is detected by the data judging circuit, a signal for printing a character corresponding to the data is delivered to a printing part (6e) so that printing can be effected according to the number of digits set in a hit counter (6db) independently of the number of characters set according to data on the number of characters per line. </p> |
