For Windows you have to use Internet Explorer (I use the latest version), Google Chrome does not work & make sure you download icloud plugin for window once you go to the website for the first time. Then go to contacts & click the settings or action button below, select all then print.
Taking a screen shot doesn't work. The actual phone numbers of the contacts do not show. Cannot even scroll down the list to show more contacts. Very frustrated. This is such a simple fix for Apple. Apple IT people must be very sadistic. Sad.
