Abstract
A method and apparatus of printing an image onto a medium uses a system having an elongate printhead with an array of marking elements including at least one distinctive group. The marking elements form at least one row, the direction of which forms a longitudinal axis of the printhead. The printhead is driven in a fast scan direction to print marks on the medium along a swath, and the medium and the printhead are movable relative to each other in a slow scan direction to print further swaths. The system is such that two adjacent marking elements of a group are operable with a time difference but are not operable simultaneously without causing defects. The printhead operates to print parallel lines at a non-zero angle with respect to the longitudinal axis of the printhead. Printing passes are repeated in the fast scan direction to print at intermediate positions between the parallel lines to print the complete image.
