Abstract
A dot line printer having printing heads of uniform characteristics, and reducing the steps number of adjustment for uniform printing quality. A dot line printer having a printing head assembly includes a plurality of spring-charged type printing heads which are linearly arrayed. The printer comprises a plurality of impact pulse generators for generating impact pulses to be applied to said printing heads; and a plurality of drive circuits, each of which is electrically connected to corresponding said impact pulse generator and to corresponding group of divided printing heads for controlling the driving of the printing heads in response to the impact pulses generated in said impact pulse generators.
