THERMAL PRINT BAR Abstract of the Disclosure A thermal printing bar, as for a facsimile printer, has a pattern of associated conductors on each side thereof to produce two rows of hot spots in the printing bar. The hot spots in one row are offset relative to the other row. By suitably sizing the hot spots, the spots in one row will at least completely fill the gaps between the spots in the other row, or can even overlap. By this means, the one row is first printed on the paper; the paper moved by the distance between the centres of the rows and then the other row printed. This provides contiguous or overlapping spots on the paper, giving improved contrast. - i -
