Constants and Data Types

Tray Mapping Modes

The tray-mapping mode constants define the current tray-mapping mode of the printer. The GXGetTrayMapping function returns a value of a tray-mapping type, which you can use to determine if you need to loop through the trays to find information.

enum {
  gxDefaultTrayMapping     = (gxTrayMapping) 0,
  gxConfiguredTrayMapping  = (gxTrayMapping) 1
};

typedef long gxTrayMapping;
