Resources Used for Printing Extensions and Printer Drivers

The Tray Count ('tray') Resource

You need to include a tray count resource, of type gxTrayCountDataType, if you support named paper trays in your printing extension or printer driver. You use the tray count resource to specify how many paper trays there are on the output device, and you provide a tray name resource (as described in the next section) for each of the trays.

Figure 6-4 shows the structure of the tray count resource.
