ABSTRACT:
Optimization of printer throughput is achieved through the use of a printhead carriage control method and a corresponding apparatus which directs acceleration of the printhead carriage based on the length of a future printhead carriage swath. According to the improved method, print data is periodically previewed to determine the length of a future swath, and the carriage is accelerated to an optimal printing velocity which is selected based on the determined swath length. The printer prints at the selected printing velocity, and then decelerates the carriage to complete the pass. During deceleration, the medium is advanced to its next position, and the print data is again previewed in order to determine the swath length for use in selecting the optimal printing velocity for the next carriage pass.
