I have an Epsom Stylus CX8400 all-in-one printer. I tried to update the drivers, but because it is not listed in the "Printer / Devises" section of the Control Panel it wouldn't let me do the update driver. If I do a Word doc it is listed as a printer option that can be used to print the document. So why is it listed there but not in the Control Panel "Printer / Devises" section? What do I do to fix this.
