I have upgraded to WIN XP. Now I find that my Calcomp Techjet Plotter will not work as there is no XP driver available. I have read that i can use the WIN NT driver and it will work. I need the following NT files to make it work. pscript.dll pscrptui.dll pscript.hlp. The Calcomp website says the files are on the WIN NT4 installation cd in the i386 folder.
