Abstract:
     The present invention relates to improvement of printer circuit matched with core of marketed miniature dot printer. The print synchronizing sinusoidal signal output by the printer core is processed in frequency doubler, shaper and frequency divider before fed to monochip computer conrolling printer head. The print density and thus the working efficiency fare raised in the condition of no change in paper width and print speed.
