Hallo to all. Please help me. I have cutter EH-721 but I have no driver for it. Where can I find it? I connected plotter with my computer by USB cabel, but computer can't find driver. I show on printscreen. How can I fix it? I tried to instal this driver https://support.uscutter.com/support/solutions/articles/14000030240-mh-mk2-driver-download , but it doesn't work. The computer said that it isn't necessary driver. P.S. I am sorry for mistakes, I am from Ukraine.
