I have Autocad 2005 and I plot to an HP Designjet 500. My operating system is XP Pro SP2. When I send a plot from autocad, it shows the print progress dialog two time and then It shows up in the Designjet Dialog two time, one plot shows up with a file size and the other plot is identical except for not having a file size. The one with a file size plots fine. The other without a file size brings up a "Document did not print" error. Any ideas? -Shane
