I recently bought a used calcomp 3024 plotter. with it came drivers for windows and instructions for loading setup and plotting. Everything seems to be right with the setup until I send a drawing to the plotter. Then it goes thru all motions as if it were going to print, but at the last point, returns pen to start position and registers a error message. I have exhausted all suggestions such as editing set up, parrarall port, serial ports. In printer properties I can see the data being sent to plotter, when it finishes that is when it shuts down and error message appears. I hope this is enough info for someone to be able to help me. I am ready to try anything reasonable. This plotter worked fine for previous owner, thanks, leboplum
