Abstract

A printer printing an image on a print medium based on print data including print dot data for each of print lines. The printer includes a print head including heating elements arranged along a direction of the print lines, and a controller finding the number of print dots on each print line and determining a first or second control mode as a control mode of the heating elements for printing each print line based on the found number of print dots. In the first control mode, the heating elements are divided into first groups including two or more adjacent heating elements and are heated at a different timing. In the second control mode, the heating elements are divided into second groups including two or more heating elements with at least two thereof spaced apart and are heated at a different timing.

Dependent claims

A printer configured to print an image on a print medium based on print data that includes print dot data for each of a plurality of print lines, comprising:

a print head including a plurality of heating elements arranged along a direction of the print lines;
and
a controller configured to find the number of print dots on each print line and determine a first control mode or a second control mode as a control mode of the heating elements for printing each print line based on the found number of print dots, wherein
in the first control mode dividing the heating elements into a plurality of first groups the controller controls the plurality of heating elements to generate heat at a different timing for each first group including two or more adjacent heating elements, and
in the second control mode dividing the heating elements into a plurality of second groups the controller controls the plurality of heating elements to generate heat at a different timing for each second group including two or more heating elements, at least two of which are spaced apart.

a print head including a plurality of heating elements arranged along a direction of the print lines;
and
a controller configured to find the number of print dots on each print line and determine any of first to third control modes as a control mode of the heating elements for printing each print line based on the found number of print dots, wherein
in the first control mode dividing the heating elements into a plurality of first groups the controller controls the plurality of heating elements to generate heat at a different timing for each first group including two or more adjacent heating elements,
in the second control mode dividing the heating elements into a plurality of second groups the controller controls the plurality of heating elements to generate heat at a different timing for each second group including two or more heating elements, at least two of which are spaced apart, and
in the third control mode, the controller controls the plurality of heating elements to generate heat at the same timing.
