The truth remains that there have been actual errors in many of the many varying editions of the KJV.
An error is still an error regardless of whether it was supposedly introduced by a typesetter, printer, editor, or translator.
No KJV-only advocate has proven that all the actual errors in the 1611 edition of the KJV was the fault of the printer.
Here is an example of a new error that was introduced into some 1980's and afterwards editions of the KJV.
Joshua 13:14
