Somehow, obviously, I'm the one being harsh...
maybe I should delete the previous ten posts, but they might help someone else one day.
The problem is either the computer, windows, corel, the roland driver, the printer cable, the plotter, or the operator, or some combination of the above. (Hardware, software, or meatware).
I can't offer anything more useful than all I have done. If you felt I was being sarcastic with some comment, maybe a bit of sarcasm crept into some things, but the advice is still pertinent.
If you cannot fix it anymore, junk it or sell it, or maybe give it to OP.
If you decide to buy a P-cut ebay special plotter, don't expect it to work any easier, though. Many people have a harder time with them than you have had with the camm1.
Please learn to use the shift button on the keyboard, as well as the period or fullstop button. You seem to be ignoring this simple request. The word "Thankyou" goes a long way, too. I wish I could help you, but I now have neither the time nor the brains to figure out a solution. I believe it has already been typed.
Good luck!
