A high speed real time print head controller is provided for supporting a high resolution vector graphics command set which is employed to perform flexible high speed generation of textured line effects. Rows of continuous graphics line information are generated by a print head controller and modified by novel texture control means and style control means so that the bit information supplied to a shift alignment means under control of the style logic means is loaded into a bit map memory one parallel word at a time to completely load a page of information in the bit map memory in the desired styled and textured pixel format for presentation to a write head buffer for printout.
