PURPOSE:To improve print quality by a mechanism wherein time for driving each printing hammer for striking a printing type on a printing type carrier is electrically computed and determined. CONSTITUTION:A high-speed printer is equipped with a pitch storage means 78 for converting into time each of all pitches between printing types 11 on a printing type carrier 10 and storing the time; a data storage means 82 for converting into time the space between the centers of printing hammers 19 and storing the time value; and a time measuring means 90 for measuring the time elapsed since the printing hammer 19 to be first driven in the previous complementary scanning has started driving. In addition, when the printing hammer 19 to be first driven in each of complementary scanning is driven, an operation-comparing means 87 provided therein reads out pitch data given by the pitch storage means 78 and time data given by the data storage means 82 to compute and determine driving timing, and to generate a coincidence output when the computed result agrees to the time given by the time measuring means 90. The output of the operation-comparing means 87 is used as a driving timing signal for the printing hammer 19 to be first driven in each of complementary scanning. |
