graphics poor when printing

Hi all, When I get my drawing and then ( make drawing from part ) The graphics when I print to my A1 printer are poor. But if i print the drawing before i ( make drawing from part ) they are brilliant. I have put my setting on the printer to it's highest quality but it still doesn't work. Is there a setting anywhere in solidworks that can up the resolution? I've been in tools/options, and changed the image quality and the performance to high but still no good. So Help, as I am at a loss. SolidworksAdministration
