ABSTRACT:
An image printing method and apparatus which can detect the edge of a printing medium on which a barcode is written while reading the barcode using one sensor unit. The apparatus for printing an image on a printing medium on which a barcode is written includes a sensor unit sensing the barcode and generating a sensing signal. A first counting unit counts the sensing signal to generate a first count value when the value of the sensing signal is changed from a high value to a low value. A second counting unit counts the sensing signal of the barcode simultaneously with the first counting unit to generate a second count value which is initialized whenever the value of the sensing signal is changed. A detecting unit detects the edge of the printing medium based on the first and second count values of the first counting unit and the second counting unit. A reading unit reads the barcode based on the second count value of the second counting unit.
