We recently migratted from a Novell network to a Windows 2003 network. Since then, we have been having problems with our HP Colorpro CAD printer. Every job we send gives us the following error: "Tray 1 Load Plain Custom". We then need to load the paper manually. (The kicker is if you preview the drawing before plotting, it will send it to the correct paper tray). I know that I have all the software print settings correct. I have tried new XP drivers without any luck. I have also found that many people have reported this problem in various discussion groups but I have not found any solutions. Can anyone help me with this one??? Keith
