摘要

PROBLEM TO BE SOLVED: To provide a stable quality of printing by preventing the quality of printing from being deteriorated even in the case of performing the printing of printing dots locally concentrating in the printing range or of the printing dots concentrating in a specific print hammer. SOLUTION: Relating to the print hammer for which the count number of the printing dots of each printing hammer has exceeded a prescribed value, the current value is changed to the direction such that the current product of the drive-current increases. The printing-dot number of the print hammer within one stroke is provided with two or more prescribed values and a pulse width of the drive-current corresponding to each prescribed value. Whenever the count number of the printing dots of each print hammer exceeds each prescribed value, it can be changed to the pulse width of the corresponding drive-current. The prescribed value is provided to the printing dot number for every print hammer within one stroke, and the value is provided individually for every N dot lines. COPYRIGHT: (C)2005,JPO&NCIPI
