Raster Package Options
The raster package options enumeration defines constants that you can use in the packageOptions field of the raster package structure, which is described in the previous section.
enum {
   gxSendAllColors   = 0x00000001,
   gxInterlaceColor  = 0x00000002,
   gxOverlayColor    = 0x00000004,
   gxUseColor        = (gxInterlaceColor|gxOverlayColor);
};
typedef long gxRasterPackageOptions;
Constant descriptions

gxSendAllColors
The driver needs to send all bands of data, even when the entire band is empty.
gxInterlaceColor
The driver needs to interlace colors because ribbon contamination is a concern on this color printer. If you use this option, you might need to use negative line feed values.
gxOverlayColor
The driver does not need to interlace colors because ribbon contamination is not a concern on this printer.
gxUseColor
This is a color printer.
