Solved this by opening Widows Administrative Tools and launching the Print Management application.  Double-clicked on "All Drivers" at the left of the screen...then, a list of printer drivers appears at the right.  There were two Xerox drivers installed (even though I had previously deleted/uninstalled all Xerox printers).  I right-clicked on both of those drivers and selected the option to "Delete" each driver.  Once this was done, Windows update didn't generate an error.
