Backing up print queues on a Windows 2008 R2 Server
To back up existing print queues on a Windows 2008 R2 Server, type “print management” or printmanagement.msc in the search dialog box. Once launched, click on Print Servers to explain the list. Right-click on the print server that contains the printer queues, and select the Export printers to a file menu option.
A wizard will walk through several screens including selecting a name and file location for the export. When the process has completed, a file with an extension of .printerExport should be present.
