Disclosed is a method to increase the printer throughput by overlapping as much as possible between index and carrier movement in a print cycle. Increasing the printer speed is often a solution to obtain higher throughput. However, the printer throughput does not increase proportionally with the printer speed. The higher the print speed is, the longer time the carrier needs to accelerate and decelerate. In a high-speed serial printer, the control software can optimize the throughput by executing independent tasks in parallel or overlapping tasks whenever possible. An example of this is repositioning the carrier for the next print line while a line-feed is performed. Another example is executing a line-feed right after the carrier reaches the last print-point of a print line.
