When I print a standard sheet with raster images on it (e.g. Any 3D view or Elevation with shadows turned on) The printer adds a series of random black lines over the page that do not show up in the print preview. (and no, they are not "Level" lines). I have tested with other printers and other computers and the same problem happens every time. I turn "raster processing" off in the print window and that does not work. The Attached image shows this (the red lines are hand drawn). The problem started in revit 7 (I think) and have never gone away. WHAT IS GOING ON HERE? IS THERE A FIX?? - Thanks.
