An electrophotographic typesetting system having a scanning means for scanning a light sensitive image support surface with an information containing light beam and for imaging said information on said surface, said system having means for driving the light beam through a curvilinear light path, means for converting said curvilinear light path to a straight line scanning locus at said surface, means supporting said surface and moving said image support surface, means providing information in digitized format including means for providing first digital data defining the identity and location of characters, font storage means providing data defining the contour of a plurality of characters with respect to a normalized encoded set of first and second coordinates, digital processing means connected to said first and second digital data for producing third digital data defining said characters, means for modulating the light beam responsive to said third digital information, said system including an optical assembly, said optical assembly having surfaces referenced to each other for mounting said means for scanning, said means to convert said curvilinear light path and said means for supporting and moving said image support surface, whereby said scanning means, said means for converting said curvilinear light path and said means for supporting and moving said image support surface are referenced to said referenced surfaces and to each other.
