<p>PURPOSE:To print with different dot density and to print in contraction by providing a plurality of specific LED heads having different dot densities. CONSTITUTION:An LED head 13a having 240DPI of dot density, an LED head 13b having 300DPI of dot density and an LED head 13c having 345 DPI of dot density are disposed. When an LED head selector 10 selects the head 13a, print data are printed in the size of 240DPI of the same magnification. When print data are contained by 300DPI, a head select signal is so controlled as to select the head 13b, and printing with the dot density of 300DPI is performed. When the data contained by 240DPI of dot density is printed in contraction to A4 size on a continuous print sheet, the head 13c is controlled to be selected.</p> |
