Patent ID: 7573600

Claim:
A printing system comprising: a printing section for forming an image with an input image data; a sensor for measuring a size of each print medium fed to the printing section, wherein each of print mediums fed is of a same size; a first comparison section for comparing a preset value set by a printer driver for a print medium's size with a measured value for the size of each print medium measured by the sensor; a counter section for counting a variable for the number of times in which a difference occurs between the preset value and the measured values, the difference being recognized as a result of the preset value and the measured value being compared by the first comparison section; a second comparison section for comparing the variable counted by the counter section with a predetermined reference number of times; a memory for storing the preset value, the counted variable, and the predetermined reference number of times; and a control section for individually controlling the first and second comparison section, the counter section and the printing section, the control section adjusting the image data based on the size of the printing mediums measured by the sensor when the counted variable exceeds the predetermined reference number of times.
