Last night uninstalled the drivers for my 3800 then reinstalled with the most recent drivers from Epson's website.
At one point it asked which port for the printer, but my only option was manual so I chose USB 1, I have know idea which port to use.
I think it's supposed automatically configure this.
This time when I tried to print, all I got was the little hour glass on the screen, then nothing. I no longer got the message "Printer Not Ready"
The print job was in the queue, but wouldn't print.
I tried two different USB cables, one of which I use on my P800, and it works there.
I still think my printer is not communicating with my PC.
If the drivers don't work, it's probably the cable that may be bad for it to not recognize the data to/from the computer.
