Acad 2005, XP, HP1055 plotter. Drawing came from consultant (we did not create it from scratch) Drawing will not plot with pen styles (drawing comes out with all pens equal, very light) We can change pen style and still plots all equal (black) All layers set to "default" as and "by color" Kicker....If we open same drawing on different computer it plots fine. Is there some setting that might over ride pen settings? Thanks in advance for any help. Paul
