ABSTRACT:
In a dot line printer that prints, for example, eight lines of dots with each single scan of a hammer bank, wherein the pins of hammers for printing the first dot line and the eighth dot line or for printing the second dot line and the seventh dot line are shifted from their respective home positions to compensate for an error causing impressions of dots to be made at an unequal pitch in a sheet feed direction as a result of consecutive forward and backward movements of the hammer bank.
