Since the install of update KB 313xxxx we can no longer print from a WPF application. The following exception occures when System.Windows.Controls.PrintDialog.PrintDocument is called.
Source: ReachFramework
Message: Source: Method not found: 'UInt32 System.Printing.PrintQueue.GetDpiX(System.Printing.ILegacyDevice)'.

Uninstalling the update resolves the issue.
Issue occurs on Windows 7, .NET 3.5/4, x86 with physical printers and not virtual ones such as Sent To OneNote or XPS. Occures on both Xerox 7380 and Intermec PF4I.
