Abstract
In an impact printing apparatus including a carriage which carries a rotary type element, the length of time required for a motor drive system for the carriage stop hunting and stabilize at a desired printing position depends on variables including the distance the carriage was moved, character pitch and the like. The apparatus senses these variables and delays hammering of the type element for printing for a length of time calculated to reduce the displacement of the carriage from the desired printing position caused by hunting to an acceptable value while maximizing the effective printing speed.
