After installing the fix from KB article 2596596 (http://support.microsoft.com/kb/2596596) you may find your charts are missing elements when printed. The missing elements can include chart titles, data lables and legends. They are seen on screen and in print preview, but when printed they don't show up.
Right now there is no fix for this problem, but Microsoft is aware and a fix will be addressed in an upcoming update. However, you can use the following workarounds:
1. Select the chart itself and then print only the chart;
2. Save the workbook to PDF format and print from Adobe;
3. Roll back the update you applied.
Thanks to Laura Holzwarth for writing up this content.
Update (2/7/2012) - The fix for this problem will be part of the February Cumulative Update, which will be released the last week of February.
