<p>A printing system (40) in which an array of VCSELs as a light bar printhead (42) directly sends an array of light beams (44) onto a photoreceptor (46) without using an imaging optical element. The VCSELs are selected which have slowly diverging light beams. The photoreceptor is placed at a predetermined distance from the VCSELs where the light beam has a width equal to a desired spot corresponding to a given printing resolution. <IMAGE></p> |
