I have had major difficulties trying to get the lineweights to plot to an HP Designjet 755cm. I can plot lineweights to the HP2500C connected to the computer but when I use the network printer and try to plot to the 755, i can not get lineweights. Please help with suggestions, I think I have tried all settings, or refer me to someone who can help with this at the least? I have the plotter pen settings to software. i have used the layers, lineweights by objects, etc, that I can think of. I must be missing something simple, either on the plotter or the ACAD setup. any help would be greatly appreciated.
