delphi中的winSpool提供了足够的信息，可以实现

Delphi(Pascal) code

Uses Winspool, printers;{-- GetCurrentPrinterHandle -------------------------------------------}{: Retrieves the handle of the current printer@Returns an API printer handle for the current printer@Desc Uses WinSpool.OpenPrinter to get a printer handle. The caller  takes ownership of the handle and <b>must</b> call ClosePrinter on it  once the handle is no longer needed. Failing to do that creates a  serious resource leak! <P>  Requires Printers and WinSpool in the Uses clause.@Raises EWin32Error if the OpenPrinter call fails.}{ Created 30.9.2000 by P. Below-----------------------------------}Function GetCurrentPrinterHandle: THandle;  Const    Defaults: TPrinterDefaults = (      pDatatype : nil;      pDevMode  : nil;      DesiredAccess : PRINTER_ACCESS_USE or PRINTER_ACCESS_ADMINISTER );  Var    Device, Driver, Port : array[0..255] of char;    hDeviceMode: THandle;  Begin { GetCurrentPrinterHandle }    Printer.GetPrinter(Device, Driver, Port, hDeviceMode);    If not OpenPrinter(@Device, Result, @Defaults) Then      RaiseLastWin32Error;  End; { GetCurrentPrinterHandle }{: Kill all pending jobs on the current printer }Procedure PurgeJobsOnCurrentPrinter;  Var    hPrinter: THandle;  Begin    hPrinter:= GetCurrentPrinterHandle;    try      If not WinSpool.SetPrinter( hPrinter, 0, nil, PRINTER_CONTROL_PURGE )      Then        RaiseLastWin32Error;    finally      ClosePrinter( hPrinter );    end;  End; { PurgeJobsOnCurrentPrinter }

windows不是对所有打印机的控制都有效。。。
所以不要过于寄于API上，尽量找下相应的SDK才行
