A swath type printer including a print carriage supported printhead (25) and a printhead positioning mechanism (91, 111, 121, 122) for adjusting the position of the printhead relative to the media axis at the end of each scan of the carriage along a carriage axis, such that dots printed by printing elements of the printhead in a sequence of a first scan and a second scan of the print carriage are interleaved along the media axis and are separated along the media axis by one-half of the predetermined printing element dot pitch.
