Abstract
An inkjet print device prints by reciprocally moving a carriage () in a main scan direction while controlling ink ejection from a print head () according to information on the position of the carriage () both in a forward movement and in a return movement. An encoder (), a first U/D counter (), a second U/D counter (), a timer (), and an interval timer () senses the position of the carriage (). The encoder (), the first U/D counter (), and the timer () senses the speed of the carriage (). A TBL memory () is used in determining a positional correction quantity at a sensed carriage speed from a positional correction quantity at a predetermined carriage speed. A head control section () controls ink ejection from the print head () based on the carriage position and the positional correction quantity.
