Karl,
Thank you so much for your info on this. We found that you are correct (as usual) that when we āPrintā to the large format printer (HP Designjet 700), the white fill/transparent background works properly. When we āPlotā, the screen fill does not work at all. Prior to this experiment we had never āPrintedā. Aside from the fill screen benefit, are there other reasons to Print instead of Plot that you are aware of? In any case, thanks again for your helpful clarification.
