The application graphs math functions to the screen, and I recently added the capability to print the graphs. The printing code is straight out of Inside Mac -- I just open a printing grafport and draw the picture. On an ImageWriter the printing looks great, but on the LaserWriter it isn't up to the capabilities of the printer. The lines of the graph, which are generated with simple LineTos and FramePolys, are thickened to match the fourfold improvement in printer resolution. What I would like, however, is for it to print the thinest lines possible, since they represent abstract lines in space and not actual objects with thickness. Is there a way to specify how the LaserWriter handles lines, either with general printing code or code that is specific to PostScript printers? Any help or pointers would be greatly appreciated.
