Adobe Reader X (10.0) – problem printing multiple documents
With Adobe PDF Reader you can print multiple documents by selecting them in Windows Explorer > Right mouse click > Print.
With version 10.0 we noticed problem - after first document is printer empty Adobe Reader X window opens. Only after it's manually closed second document is printer and so on.
This seems to be caused by newly introduced Adobe Reader "Protected Mode"
Open Adobe Reader X > Edit > Preferences > General - Uncheck "Enable Protected Mode at startup"
Caution: Protected mode is a new security feature in Adobe Reader X and by disabling it you potentially increase security risks.
