A laser printer produces an image of raster scan lines exhibiting a pitch distance p. The printer includes a photoreceptor and n laser sources, where n>/=2. First and second sets of laser sources, in one embodiment, produce plural optical beams which, when imaged on the photoreceptor, are separated by pitch distance p in the direction of movement of the photoreceptor. The first set and second sets of laser sources are separated by a distance SPR=c(1+qr)p, where: c=number of laser sources in each set, q=an integer, and r=number of rows of laser sources in both the first and second sets. The optical beams are modulated with pixel value data in accordance with a correspondence of image scan lines and positions of the optical beams on the photoreceptor. The photoreceptor is moved by a distance (qxcxr)p between scans. In such manner, an interleaving of the scan lines is achieved, which allows substantial separation of laser diodes on a laser diode chip.
