Abstract
In a dot line printer having a plurality of print hammers which are arranged to print a plurality of dot lines simultaneously when a hammer bank on which the print hammers are mounted performs one scan from one extreme to another, the dot lines originally assigned to the print hammers for printing are changed provided that a particular print hammer is driven an undue number of times when the originally assigned positions of the print hammers are maintained in the subsequent scans of the hammer bank.
