In AutoCAD 2004, i have a series of DWG's to plot. Those DWG's are all made from the same parameters, including colors, layers, text style, layout......... so everything "seems" to be created on the same basis........... but But when i am trying to plot on my HP DesignJet 650 C, it seems that i cannot obtain the same result from a drawing to another........ and i assure you, it's been many year i work with AutoCAD, that i use the same platting parameters from on to another ............... Those drawing comes from another office ....... i use the HP 650 C driver optimized for AutoCAD 2004........ Please help me ... Jack Morency Québec city
