1. A printer for printing on a printing medium having a mark, comprising:

  • an optical sensor operable to generate a signal based on a position of the mark of the printing medium with respect to the optical sensor;

    a feeding section operable to perform feeding of the printing medium;

    a controller operable to control the feeding of the printing medium based on the signal; and

    a printing section operable to print images on the printing medium, wherein the optical sensor is operable to generate the signal by sensing a change of transmissivity of the printing medium;

    the optical sensor is a CCD line sensor having a longitudinal direction along which a plurality of sensor cells constituting the CCD line sensor are provided;

    the mark is a stripe drawn on the printing medium;

    the stripe is substantially a line;

    the line is drawn substantially perpendicular to a feeding direction along which the feeding section feeds the printing medium;

    the line and the longitudinal direction of the CCD line sensor intersect at an angle which is substantially non-perpendicular; and

    the line traverses all of the sensor cells while the printing medium is being fed.
