In the following Members section, function pointers are listed in the order they are specified within the PRINTPROVIDOR structure. To see function descriptions grouped by related capabilities, see Functions Defined by Print Providers.

Members

fpOpenPrinter

(Required.) Pointer to the provider's OpenPrinter function, which is described in the Platform SDK documentation. However, at the provider level, this function must supply one of the DWORD return values listed in the following table.

Return Value	Definition
ROUTER_SUCCESS	The provider supports the specified printer and has opened it.
ROUTER_STOP_ROUTING	The provider supports the specified printer, but an error occurred and the printer could not be opened. It is assumed that no other provider can support the printer. The function must call SetLastError.
ROUTER_UNKNOWN	The provider does not support the specified printer. The function must call SetLastError and specify ERROR_INVALID_NAME.

The router calls each provider until one of them returns ROUTER_SUCCESS or ROUTER_STOP_ROUTING. If the provider returns ROUTER_SUCCESS, it must also return a unique handle. (For more information, see Introduction to Print Providers.) The router first attempts to call the provider's OpenPrinterEx function. If that function is not supported, the router calls OpenPrinter.

fpSetJob

(Required.) Pointer to the provider's SetJob function (described in the Platform SDK documentation).

fpGetJob

(Required.) Pointer to the provider's GetJob function (described in the Platform SDK documentation).

fpEnumJobs

(Required.) Pointer to the provider's EnumJobs function (described in the Platform SDK documentation).

(Optional. Can be NULL.) Pointer to the provider's DeletePrinter function (described in the Platform SDK documentation).

fpSetPrinter

(Required.) Pointer to the provider's SetPrinter function (described in the Platform SDK documentation).

fpGetPrinter

(Required.) Pointer to the provider's GetPrinter function (described in the Platform SDK documentation). If you are writing a network print provider and GetPrinter is returning a PRINTER_INFO_2 structure, the function should supply only the cJobs and Status structure members. The local print provider supplies the rest of the structure members.

fpEnumPrinters

(Required.) Pointer to the provider's EnumPrinters function (described in the Platform SDK documentation).

fpAddPrinterDriver

(Optional. Can be NULL.) Pointer to the provider's AddPrinterDriver function (described in the Platform SDK documentation). If the provider does not support the specified driver or server, it should specify ERROR_INVALID_NAME to SetLastError before returning FALSE.

fpGetPrinterDriver

(Optional. Can be NULL.) Pointer to the provider's GetPrinterDriver function (described in the Platform SDK documentation). The router first attempts to call the provider's GetPrinterDriverEx function. If that function is not supported, the router calls GetPrinterDriver.
