ABSTRACT:
This invention relates to a printing apparatus and a conveyance control method capable of simultaneously operating plural encoder sensors and executing more accurate printing medium conveyance control. A first encoder sensor provided adjacent to a first conveyance roller detects the conveyance amount of a printing medium by the first conveyance roller provided in the conveyance path of the printing medium. A second encoder sensor provided adjacent to a second conveyance roller detects the conveyance amount of the printing medium by the second conveyance roller provided in the conveyance path of the printing medium at the downstream side from the first conveyance roller in the conveyance direction of the printing medium. For example, conveyance of the printing medium is controlled on the basis of the output signals from the first and second encoder sensors when a tail end of the printing medium is located adjacent to the first conveyance roller.
