Module Name:
Winspool.c
Abstract:
Bulk of winspool.drv code
Author:
Environment:
User Mode -Win32
Revision History: mattfe april 14 94 added caching to writeprinter mattfe jan 95 Add SetAllocFailCount api
13-Jun-1996 Thu 15:07:16 updated -by- Daniel Chou (danielc) Make PrinterProperties call PrinterPropertySheets and DocumentProperties call DocumentPropertySheets
SWilson Dec 1996 - added GetPrinterDataEx, SetPrinterDataEx, EnumPrinterDataEx, EnumPrinterKey, DeletePrinterDataEx, and DeletePrinterKey
khaleds Feb 2000 - Added DocumentPropertiesThunk, AddPortWThunk, CongigurePortWThunk, DeleteProtWThunk, DeviceCapabilitesWThunk, PrinterPropertiesWThunk, DocmentEvenThunk, SpoolerPrinterEventThunk Renamed the above native functions from xx to xxNative
Khaleds Mar 2000 - Added SendRecvBidiData Khaleds Mar 2001 - Fix for WritePrinter LazarI - Oct-30-2000 added GetCurrentThreadLastPopup & fixed StartDocDlgW
