ya.. i've read that a couple times while trying to find my solution. I don't have a cable that connects like that ( not even sure what they're called.. one port on the plotter is the big one with the clips and the other looks similar to a parallel port.. but has a lot more holes for pins - good grief i feel really stupid.
I don't even have a manual for this plotter.. i've read on another manufacturers manual a way to reset the plotters to get rid of the error message.. but I can't find any info on this derelict Vinyl Express.
