Module Name:

    prndata.c

Abstract:

    This module provides all the public exported APIs relating to Printer
    and Job management for the Local Print Providor

Author:

    Dave Snipp (DaveSn) 15-Mar-1991

Revision History:

    mattfe Apr 5 95 - we keep the driver data key open
    and then just do the read / write operations here.

    Steve Wilson (SWilson) Jan 11 96 - Added Server handle functionality to Get & setprinterdata
                                       and pretty much changed everything in the process.

    Steve Wilson (SWilson) May 31 96 - Added SplEnumPrinterData and SplDeletePrinterData
    Steve Wilson (SWilson) Dec 96 - Added SetPrinterDataEx, GetPrinterDataEx, EnumPrinterDataEx,
                                    EnumPrinterKey, DeletePrinterDataEx, and DeleteKey
