Name:

    PrinterPropPageProvider

Routine Description: 

    Entry-point for adding additional device manager property
    sheet pages.  This entry-point gets called only when the Device
    Manager asks for additional property pages.

Arguments:

    pinfo  - points to PROPSHEETPAGE_REQUEST, see setupapi.h
    pfnAdd - function ptr to call to add sheet.
    lParam - add sheet functions private data handle.

Return Value:

    BOOL: FALSE if pages could not be added, TRUE on success
