I purchased a HP designjet 600 plotter. I have a window vista computer. It won't plot
I purchased a HP designjet 600 plotter. I have a Windows Vista laptop. I had to purchase a cable that had a parallel connection on one end and the other end is a usb connection. I downloaded a printer driver for windows xp because the drivers didn't exist for windows vista. I downloaded this from HP's website. It looks like a communication problem between the plotter and the computer. When I run a test mode on the plotter it works fine. Need your help as soon as you can. I am being stubborn and trying to stay up until I can get it to plot. Thanks for any advice.
