I was trying to configure ADT to plot to a calcomp 5536 tech jet 720. I could plot if I used the windows system printer, but the output would scramble some. I'd use the built in calcomp drivers, but when I try to send a plot using those, AutoCAD tries to save a .plt file. The calcomp is on a network server running windows 2k and the pc with ADT is running win 2k. I'd try updating the windows drivers, but calcomp is dead and there don't seem to be any drivers for anything newer then windows 98 and AutoCAD 14.
