Abstract: PURPOSE:To perform a high-speed and multi-gradation recording by a method wherein a conduction time to printing elements is held as binary conduction data having two or more digits, one of the digits is supplied to a selection shift register, while a pulse of a length obtained by multiplying a set reference time by a weight corresponding to the digit is generated. CONSTITUTION:Conduction data which is a conduction time to a corresponding printing element represented by n-bit binary data of two or more digits is used as printing density data for one line for each of printing elements 11-1-11-L. A signal of one digit of the data is fetched to be transferred to a shift register 13 as a signal for determining the presence or absence of the conduction to the printing element 11. Furthermore, a weight is determined for every digit of the n-bit binary data, and a conduction time width corresponding to the digit is obtained by multiplying a reference time DELTAt by this weight. The printing element which is determined as the presence of conduction is electrically conducted according to the conduction time width. After that, a similar action is conducted for every digit. In this manner, in printing data for one line, the transfer number to the shift register and the conduction number to the printing elements are made equal to the digit number of the n-bit binary data, and a printing time can be reduced.
