Claims

[Scope of Claim for Utility Model Registration] The heating resistors for m dots arranged on the printing line are divided into heating resistor groups for n strobes (where m>n), and the heat generation in each heating resistor group is Connect the AND circuit individually to the resistor,
A strobe signal corresponding to each heating resistor group is commonly given to one input part of each AND circuit corresponding to each heating resistor group, and print data is given individually to the other input part. A line printer configured as shown in FIG. a counter that counts the number of heat generation data in one strobe's worth of print data until a reset signal is given; a memory that stores the number of heat generation data that is the count value of the counter; and a number of heat generation data that is given from the memory. an input section for outputting n strobe signals to one input section of each of the AND circuits, and an output section for supplying a shift clock to the shift register;
an output section that outputs a reset signal to the counter when print data for a strobe has been transferred to the shift register; and an output section that outputs a reset signal to the counter when print data for one print line has been transferred to the shift register; and a control circuit having an output section for supplying the heat generation data to the circuit, the control circuit comprising a totaling means for summing the number of heat generation data, a setting output means for setting and outputting an upper limit value of the number of heat generation data, and a control circuit having an output unit for summing the number of heat generation data, a setting output means for setting and outputting an upper limit value of the number of heat generation data, and a control circuit that outputs the heat generation data from the summing means. Judgment means for determining whether the total value of the number of data exceeds the upper limit value of the number of heat generation data, and when the total value of the number of heat generation data exceeds the upper limit of the number of heat generation data as a result of the determination, printing of the strobe portion that does not exceed the upper limit value. A line printer comprising: a strobe control means for controlling output of a strobe signal so as to print data.
