ABSTRACT:
The invention relates to a thermal printing head having a plurality of heating elements arrayed in both column and row directions, which can be driven selectively and independently. A first column group is comprised of two or more columns each having heating elements which are aligned in the row direction, and which can be independently sequentially driven. A second column group is comprised of two or more columns, also having heating elements aligned in the row direction, but with the rows being offset in the column direction as compared with the rows of the first column group. The arrangement allows the double printing of each printable dot, yet facilitates the wiring of the individual heating elements by providing a larger space between adjacent rows and column groups.
