PRINTING CONTROL APPARATUS OF PRINTER

摘要

PURPOSE:To prolong the life of a printing head, by securing a necessary min. current non-supply time even if the current supply time to a printing head became long. CONSTITUTION:After the supply of a current to a printing head was performed, a current non-supply time 34 is provided consciously by such a method wherein a reset signal 32 is issued to a counter circuit C 30 from a central control apparatus 1 immediately after the output signal 9 of a counter circuit B8 came to an H-level and the output signal 31 at this time comes to an L-level and is changed to an H-level signal when the counting of the output signal 7 of a VCO circuit 6 starts to count the predetermined number of the signals 7. The L-level time of the output signal 31 of the counter circuit C30 comes to the current non-supply time 34.
