+<h1>PrintFramework</h1>
+
+This is an overview of the classes and methods used to print documents.
+It also demonstrates how to do print previews and invoke the printer
+setup dialog.
+
+<p>Classes demonstrated here:<P>
+<ul>
+    <li><b>wx.Printout()</b> - This class encapsulates the functionality of printing out 
+        an application document. A new class must be derived and members overridden 
+        to respond to calls such as OnPrintPage and HasPage. Instances of this class 
+        are passed to wx.Printer.Print() or a wx.PrintPreview object to initiate 
+        printing or previewing.<P><p>
+        
+    <li><b>wx.PrintData()</b> - This class holds a variety of information related to 
+        printers and printer device contexts. This class is used to create a 
+        wx.PrinterDC and a wx.PostScriptDC. It is also used as a data member of 
+        wx.PrintDialogData and wx.PageSetupDialogData, as part of the mechanism for 
+        transferring data between the print dialogs and the application.<p><p>
+
+    <li><b>wx.PrintDialog()</b> - This class represents the print and print setup 
+        common dialogs. You may obtain a wx.PrinterDC device context from a 
+        successfully dismissed print dialog.<p><p>
+        
+    <li><b>wx.PrintPreview()</b> - Objects of this class manage the print preview 
+        process. The object is passed a wx.Printout object, and the wx.PrintPreview 
+        object itself is passed to a wx.PreviewFrame object. Previewing is started by 
+        initializing and showing the preview frame. Unlike wxPrinter.Print, flow of 
+        control returns to the application immediately after the frame is shown.<p><p>
+</ul>
+
+<p>Other classes are also demonstrated, but this is the gist of the printer interface
+framework in wxPython.
