A friend in another office has a problem with printing autocad. He has an old computer with windows 98 which will print autocad 2000 fine. The problem is his new computer with windows xp prints the lines all funny and dotted. He wants to get this fixed. He has an HP 430 large plotter and a Hp 5p laser printer for 8.5x11 and 11x17. Any suggestions for what I should look for when i go over? (all ready thinking that he has shaded plot on or a bad ctb file)
