Global defaults for the ExportDocToXPS command can be set in the [Configuration] section of the dp.ini file.
ExportDocToXPS.OptimiseForPrint
Set to Y to optimise the XPS document for printing. This will improve the rendering of the XPS file but generate larger XPS files. Set to N to optimise the XPS document for viewing on a screen.
ExportDocToXPS.OptimiseForPrint=(Y or N)
If omitted this setting defaults to N.
ExportDocToXPS.FontBitmaps
Determine the default handling of fonts whose license forbids inclusion into the XPS document. Set to Y to include these fonts as bitmaps. Set to N to include a reference to the font and leave it to the viewer to select an appropriate (substitute) font.
ExportDocToXPS.FontBitmaps=(Y or N)
If omitted this setting defaults to Y.
