-<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.
