If you have a 3880 than install the 3880 driver. The reason why I said 3800 was because the icon on the screen photo you shared said 3800. It may be worth double checking that you actually do have a 3880 if the windows OS thought you had a 3800 on USB connect.
I finally understood where the error lies. I went with a PC to an acquaintance who has a 3880 and I tried to connect it to his and the software works, I came to the conclusion that the USB port of the motherboard does not work. I must say that I replaced the motherboard a short time ago because the white sheet came out, then it started to print again, but I could not align the head with the epson display and therefore I thought of using the software. I did some PC printing, then suddenly it stopped working, the PC does not recognize the printer and consequently the adjustment program. Now the problem is to repair the USB port on the motherboard. Anyone have an idea? I have to replace it. Thanks for the answers and for the time you have dedicated to me.
