Abstract
To prevent undue elevation of temperature in a hammer assembly but to maintain the maximum printing speed, when a scheduled number of drivings at which print hammers are to be driven during one scan of a manner bank which follows the currently performing scan, exceeds a first reference number, one dot line printing is completed with a plurality of scans of the hammer bank so that dot line print density in each scan of the hammer bank does not exceed, for example, 35%. If, however, high density printing exceeding 25% continues for an extended period of time more than one scan time, the printing operation is temporarily halted.
