HP Photosmart C309G 3 in 1. it won't print black/grayscale documents from the computer or scanned. it will print grayscale pictures either from the computer or scanned. Ran print doctor and reloaded drivers. No change. Unit is connected thru USB and is also available on WiFi. it had been running just fine in this configuration until a week or so ago. It may have changed when I "upgraded" to Internet Explorer 11.
