I tested this with the demo and it worked perfect. I have not connected it to a computer to see if it will take commands from the computer or print from a computer. It comes with a cover, I’m not sure if this is the cover for this exact plotter but when I got it, it came with it. I do have eight pens that come with this. They are used, but they work, I don’t know how much they have been used, but it would be a good starter. It also comes with the power cord. I took pictures of the cosmetic issues. There’s obviously scratching on the cover and a crack next to the carousel on the cover. There are some places where stickers were and somebody peeled them off. You can see where they were. There’s a white spot on the inside of the lid when you lift it up.
