Python win32print 更改高级打印机选项

Question

我正在使用 python 2.7 和 win32print。我可以成功地改变纵向和横向的方向：

PRINTER_DEFAULTS = {"DesiredAccess":win32print.PRINTER_ALL_ACCESS}  
pHandle = win32print.OpenPrinter('300LN1', PRINTER_DEFAULTS)  
properties = win32print.GetPrinter(pHandle, 2)  
pDevModeObj.Orientation = 2  
properties["pDevMode"]=pDevModeObj   
win32print.SetPrinter(pHandle,2,properties,0) 

但是，我想更改我的打印机的一些自定义属性，但似乎找不到执行此操作的位置。这是我要更改的选项卡之一：http://dl.dropbox.com/u/584330/print.jpg。我相信当启用“高级打印功能选项”时，可以访问这些选项。

附加信息（代码）：

devmode=pDevModeObj  
for n in dir(devmode):  
  print "%s\t%s" % (n,getattr(devmode,n))  

输出：

[编辑] 我刚刚尝试了以下代码：

win32print.DocumentProperties(0, pHandle, '300LN1', None, None, 5)

这会弹出我要修改的属性窗口。

另外，您知道是否可以要求打印机在打印到 300 页后停止打印？

from ctypes import windll
windll['winspool.drv'].AdvancedDocumentPropertiesA(None, pHandle.handle, '300LN1', None, None)
