I mentioned in another thread a while back that a client of ours with a DJ500 couldn't print from AutoCAD using the Windows drivers (Win2k default or HP v5.32). No amount of unloading and reloading helped. Either nothing would come out or a "memory error" would occur when it was selected. All other Windows applications could print to it fine. On a whim I setup a DesignJet 750c Plus C4709B using the built-in AutoCAD drivers. Of course it complained a bit about sharing the port with the Windows driver, but it works. This was using AutoCAD 2000i and using a DirectJet port (iow it was connected to the network and not a local port). Hope this helps someone else, Stef
