python 调用IEHtmlWindow打印网页
编写环境：
1、ActivePython-2.7.2.5-win32-x86
2、wxPython2.8-win32-unicode-2.8.12.1-py27
3、wxFormBuilder_v3.3.3-beta
以下代码是演示怎样利用IEHtmlWindow载入网页，并实现打印预览和打印的的功能：

wx.Frame.__init__ ( self, parent, id = wx.ID_ANY, title = wx.EmptyString, pos = wx.DefaultPosition, size = wx.Size( 674,421 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL )
self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )
self.menu = wx.MenuBar( 0 )
self.menu1 = wx.Menu()
self.LoadPage = wx.MenuItem( self.menu1, wx.ID_ANY, u"打开文件", wx.EmptyString, wx.ITEM_NORMAL )
self.menu1.AppendItem( self.LoadPage )
self.PrintPreview = wx.MenuItem( self.menu1, wx.ID_ANY, u"打印预览", wx.EmptyString, wx.ITEM_NORMAL )
self.menu1.AppendItem( self.PrintPreview )
self.Print = wx.MenuItem( self.menu1, wx.ID_ANY, u"打印", wx.EmptyString, wx.ITEM_NORMAL )
self.menu1.AppendItem( self.Print )
self.menu.Append( self.menu1, u"文件" )

self.ie.AddEventSink(self)

self.Bind( wx.EVT_MENU, self.LoadPageOnMenuSelection, id = self.LoadPage.GetId() )
self.Bind( wx.EVT_MENU, self.PrintPreviewOnMenuSelection, id = self.PrintPreview.GetId() )
self.Bind( wx.EVT_MENU, self.PrintOnMenuSelection, id = self.Print.GetId() )

app = wx.PySimpleApp()

frm.Maximize()
frm.Show()
app.MainLoop()
