I'm trying to plot a plot file to send to a print house. They want a plot file made to an HP750C Plus which is a plotter we don't own or have connected to the computer. I've configured an HP750C Plus under the Plotter Manager. I've tried plotting with the ".ctb" file I normally use for our hp600 but all my plot previews show up in color. I don't want a color plot - I want a black and white plot. Can anyone help me figure out how to do this. Thanks!
