Hello, I am having the same problem, but I can't seem to find my printer in that folder. I just added a wireless printer to my network and when I pull up the CP the old printer that was a HP Deskjet 3940 (small printer) now has the Multifunction printer icon, which should be for the new Epson Workforce printer and the Epson was given the small printer icon of the old HP. I went to the en-us folder as you described, but only found my old printer info there with the MF icon. I could not find my new Epson in there at all. I found: my laptop, my mouse, my old printer, a scandisk, and a generic receiver (I think this is the router?)
Also, if I could find that folder, can you explain just how you go about changing the icon? I noticed you talked about editing the xml. file, but where do I find the other icon to exchange?
Thanks, Meri
