Abstract
A printer and a control method for a printer can externally detect the number of elements in the line head, and can determine the dot density of the line head from the detected number of elements. The printer has a thermal headhaving an array of plural elements for forming print dots, a plural stage shift registerthat shifts the input data according to a clock signal, a latchthat temporarily stores the output from each stage (-to-) of the shift register, a driverthat outputs the data held in each latch to the element of the thermal headcorresponding to each latch as print data based on a strobe signal, a output terminalthat outputs the output data of the last stage of the shift register, an element count detection data generating unitthat inputs to the shift registerinput data of which the value corresponding to the first clock pulse is 1 and all following values are 0, and an element number counting unitthat detects the number of elements by counting the clock pulses until the data output from the output terminalis 1.
