What industry are you in? How critical is an actual line width on a print to your customer/contractor?
How long have you used AutoCAD in your field? Have you had any formal training for printing output in your field with AutoCAD? Are you the only AutoCAD user at your company? I ask these last question because you are now asking about exact needs that work only for you, so you need to share more information instead of asking questions (hope that makes sense).
