Provided is a method and an apparatus for controlling the speed of a printing medium fed to an image printing apparatus. The apparatus includes a compensation waveform storage unit, a compensation delay amount determiner, and a ripple compensator. The compensation waveform storage unit stores a compensation waveform used to compensate for a periodic ripple error of the speed, obtained by analyzing positional information of the printing medium. The compensation delay amount determiner determines a delay amount. The ripple compensator applies the compensation waveform to the printing medium supply device with a delay corresponding to the compensation delay amount to compensate for the ripple error. The print quality is enhanced by uniformly supplying the printing medium to the image printing apparatus by compensating for the periodic ripple error. |
