| description | There is provided a liquid ejection head that includes a plurality of liquid chambers (10) each with an activation element (21) for generating a droplet ejected through an ejection opening, an ejection opening plane (4) with at least two ejection opening groups with a plurality of ejection openings ejecting droplets onto a print medium, whereby said groups are arranged in the ejection opening plane across the print medium conveying direction and wherein the ejection opening groups are arranged side by side in the ejection opening plane, the plurality of ejection openings of at least one ejection opening group (81, 91, 101) are arranged in a zigzag shape, and the plurality of ejection openings of the further ejection opening groups (82, 92, 102) are arranged in such a staggered manner that the time differences when droplets ejected from adjacent openings land on the print medium for all droplets forming a printed line across the print medium conveying direction is substantially equal. |
