A plurality of dot elements such as print wires for a serial dot matrix print head are divided into four groups with the distance of (M+1/4)P, while the distance between adjacent dot elements is maintained as (N+1/2)P; where M and N are integers and P is a pitch or a horizontal resolution, that is, a minimum dot spacing along a print line. This arrangement decreases a peak current load for a whole print head and minimizes magnetic cross-talk between adjacent magnetic actuators for the corresponding dot elements. The four-time-actuations by 1/4 timing shift achieved by this arrangement averages the current consumption and reduces the heat generated at the print head, which improves print performance. Each of Figs. 1A and 1B shows a wire arrangement at the tip of a print head having 24 print wires. Print wires No. 1 through No.
