I just found this top the other day. Our plotter offers more than 40 different paper size options. We have a custom paper size that is 36" x 144". I have to scroll all the way down to select it. What a pain. To reduce these to just the ones that you use, go to plot dialog box, plot device tab, properties, filter paper sizes and deselect the size that you do not want posted in the plot dialog box. I had to restart AutoCAD to get them to update.
