I've spoke to Autodesk & HP support and have upgraded drivers, even upgraded to Windows 2000 Pro, with help from our IT support changed the network settings, but still having trouble with :~
a) memory problems "out of memory, data lost" on large format plots A1-A0
b) and portrait/ landscape issues described above on all format plots A4-A0.
HP650c and Map 6 just don't seem to work, any help would be grateful. 🙂
