Zusammenfassung:The high-speed printer eliminates lag times and uses a continuously rotating disc-like print element. A continuous drive moves the print carrier along the print line, while superimposing upon this uniform constant velocity drive a second drive force and velocity causing the carrier to either be accelerated or retarded to properly position a character independent to the amount of time required to bring the next succeeding character into print position. This is accomplished by knowing the distance between characters on the print wheel and determining the amount of time necessary to rotate the print wheel from a first position to a second position.
