Prints are not going to the print queue even after the hotfix (kb2616471) has been installed.
Group Policy settings do not allow http printing.
Check the Windows Event Viewer. If you see event id 372 processor: 1260 or event id 372 processor: 0, your IT team will need to address the Group Policy settings to allow http printing.
