Abstract
A method of, and a system for, controlling a constant current hammer in a carrier type daisy wheel printer. A logic table is utilized and first addressed with a carrier velocity code corresponding to character selection time. The table output is a sync point for determining hammer turn on time. The table is next addressed with a combination code made up of the velocity code and a code corresponding to the desired impact force. The table output this time is the actual turn on time for the hammer from the sync point. The on time of the hammer is then controlled by the desired impact force code. This code is also utilized to control the beginning of selection for the next character.
