The default is EmfType.EmfPlusDual.
If your printer needs to scan the output for data (e.g. a fax number; a case in point is Tobit Faxware) and fails, try setting this to EmfType.EmfOnly.
Note that this property ONLY affects printing of standard .NET PrintDocument documents, and has no bearing on other supported document types.
