EMF: Enhanced Meta Files

A 32-bit version of the Windows Meta File format with additional commands. EMF is also used as a graphics language for printer drivers. When the "Enable Enhanced Functions" check box is checked in a Windows printer driver under the "Advanced" tab, the files that appear in the spool directory will contain EMF (or possibly EMF+?) commands. When the file is de-spooled, it is converted to the specific printer language by the driver.

There is also a Compressed Windows Enhanced Metafile (EMZ).

See GdiPlusEnums.h  and WinGdi.h in the Windows SDKs. The following appear to have been tacked on after the original EMF spec:
